What is the product in this reaction? What are its properties

Answers

Answer:

In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can’t change one element into another in a chemical reaction — that happens in nuclear reactions. Instead, you create a new substance with chemical reactions.

In general terms, a chemical reaction follows this format:

Reactants→Products

For example, take a look at the reaction that occurs when you light your natural gas range. Methane (natural gas) reacts with the oxygen in the atmosphere to produce carbon dioxide and water vapor. The chemical equation that represents this reaction is written like this:

Methane and oxygen (oxygen is a diatomic — two-atom — element) are the reactants, while carbon dioxide and water are the products.

Explanation:

In the given incomplete chemical reaction, the product formed are [tex]\rm CO_2[/tex] and [tex]\rm H_2O[/tex], respectively.

Product is the final result in a chemical reaction where reactants react to produce new substance.

The complete balanced reaction for the given reaction is expressed as:

[tex]\rm CH_4+2O_2\rightarrow CO_2 + 2H_2O[/tex]

In this reaction, methane undergoes combustion reaction in presence of oxygen to produce [tex]\rm CO_2[/tex] and [tex]\rm H_2O[/tex] as the final product.

Properties of the final products are:

[tex]\rm CO_2[/tex] (carbon dioxide) is a colorless, odorless gas that is denser than air. It is non-flammable, non-toxic, and does not support combustion. It is a greenhouse gas, which means that it contributes to global warming and climate change.

Water is a colorless, odorless, and tasteless liquid that is essential for life. It helps in various metabolic process taking place within human body.

Therefore, the complete and balanced equation for provide equation with final product is [tex]\rm CH_4+2O_2\rightarrow CO_2 + 2H_2O[/tex].

What is the molar concentration (in moles/L) of a solution made with 3.744 g of Mg(NO3)2 dissolved in enough water to make 50.0 mL of solution?

Answers

Answer:

The molar concentration of a solution made with 3.744 g of Mg(NO₃)₂ dissolved in enough water to make 50.0 mL of solution is [tex]0.5 \frac{moles}{L}[/tex]

Explanation:

Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

[tex]molarity=\frac{number of moles}{volume}[/tex]

In this case:

Mg: 24.3 g/moleN: 14 g/moleO: 16 g/mole

So, the molar mass of Mg(NO₃)₂ is:

Mg(NO₃)₂= 24.3 g/mole + 2*(14 g/mole + 3*16 g/mole)= 148.3 g/mole

So, if you have 3.744 g of Mg(NO₃)₂, you can apply the following rule of three: if 148.3 grams of Mg(NO₃)₂ are present in 1 mole, 3.744 grams in how many moles are present?

[tex]moles=\frac{3.744 grams*1mole}{148.3 grams}[/tex]

moles= 0.025

Then you have:

number of moles=0.025volume= 50 mL= 0.05 L (being 1,000 mL= 1 L)

Replacing in the definition of molarity:

[tex]molarity=\frac{0.025 moles}{0.05 L}[/tex]

you get:

[tex]molarity=0.5 \frac{moles}{L}[/tex]

The molar concentration of a solution made with 3.744 g of Mg(NO₃)₂ dissolved in enough water to make 50.0 mL of solution is [tex]0.5 \frac{moles}{L}[/tex]

The molar concentration of the solution is 0.506 M

The molar concentration of a solution is known as molarity. The molarity of a solution is defined as the moles of a solute per liter of a solution.

It can be expressed as:

[tex]\mathbf{Molarity = \dfrac{moles \ of \ solute}{volume \ of \ the \ solution}}[/tex]

The molar mass of magnesium nitrate Mg(NO3)2 = 148.3 g/molThe mass of the solute Mg(NO3)2 = 3.744 g

The relation used in determining the number of moles is:

[tex]\mathbf {number \ of \ moles = \dfrac{mass}{molar \ mass}}[/tex]

[tex]\mathbf {number \ of \ moles = \dfrac{3.744 \ g}{148.3 \ g/mol}}[/tex]

[tex]\mathbf {number \ of \ moles = 0.0253 \ g/mol}[/tex]

[tex]\mathbf{Molarity = \dfrac{moles \ of \ solute}{volume \ of \ the \ solution}}[/tex]

[tex]\mathbf{Molarity = \dfrac{0.0253 \ g/mol}{0.05 \ L}}[/tex]

[tex]\mathbf{Molarity =0.506 \ M}[/tex]

Therefore, we can conclude that the molar concentration of the solution is 0.506 M

2.03X10^23
O 1.014X1023
5.07X10^22
O 2.54X10-22​

Answers

Answer:

1.014×10²³ atoms

Explanation:

Given data:

Volume of tungsten = 1.6 cm³

Density of tungsten = 19.35 g/cm³

Number of atoms of tungsten = ?

Solution:

First of all we will calculate the mass of tungsten.

density = mass/volume

by putting values,

19.35 g/cm³ = mass/1.6 cm³

Mass = 19.35 g/cm³× 1.6 cm³

Mass = 30.96 g

Number of moles of tungsten:

Number of moles = mass/molar mass

Number of moles = 30.96 g/ 183.84 g/mol

Number of moles = 0.1684 mol

1  mole contain 6.022×10²³ atoms.

0.1684 mol × 6.022×10²³ atoms / 1mol

1.014×10²³ atoms

you take 295.5 g of a solid at 30.0 c and let it melt in 425 g of water. the water temperature decreases from 85.1 c to 30.0 c. calculate the heat of fusion of this solid

Answers

Answer:

[tex]\Delta _{fus}H=332 \frac{J}{g}[/tex]

Explanation:

Hello!

In this case, since the heat of fusion of a solid substance stands for the energy required to melt it, which is a phase transition from solid to liquid, we can see that the heat lost by water is that gained by the solid, so we can write:

[tex]Q_{solid}=-Q_{w}[/tex]

Thus, by using the water data and its specific heat (4.184), we obtain:

[tex]Q_{solid}=-m_{w}C_{w}(T_f-T_i)\\\\Q_{solid}=-425g*4.184\frac{J}{g\°C}*(30.0-85.1)\°C\\\\ Q_{solid}=97,978.82J=98.0kJ[/tex]

Next, since the heat of fusion of a substance is usually represented in terms of energy per amount of substance, we use the mass of solid to obtain:

[tex]\Delta _{fus}H=\frac{98.0kJ}{295.5g}\\\\ \Delta _{fus}H=0.332\frac{kJ}{g}=332 \frac{J}{g}[/tex]

Best regards!

The heat of fusion of the solid is 0.332 KJ/g or 332 J/g

We'll begin by calculating the heat loss by the water. This can be obtained as follow:

Mass of water (M) = 425 g

Initial temperature of water (T₁) = 85.1 °C

Final temperature (T₂) = 30 °C

Change in temperature (ΔT) = T₂ – T₁ = 30 – 85.1 = –55.1 °C

Specific heat capacity of water (C) = 4.184 J/gºC

Heat loss (Q) =?

Q = MCΔT

Q = 425 × 4.184 × –55.1

Q = –97978.82 J

Divide by 1000 to express in KJ

Q = –97978.82 / 1000

Q = –97.98 KJ

Finally, we shall determine the heat fusion of the solid.

Heat loss by water = –97.98 KJ

Heat gained by the solid (Q) = 97.98 KJ

Mass of solid (m) = 295.5 g

Heat of fusion (Hf) =?

Q = m•Hf

97.98 = 295.5 × Hf

Divide both side by 295.5

Hf = 97.98 / 295.5

Hf = 0.332 KJ/g or 332 J/g

Volume of CO₂ formed = ?

Temperature = standard = 273 K

Pressure = standard = 1 atm

Solution:

Chemical equation:

Number of moles of Fe₂(CO₃)₃ :

Number of moles = mass/molar mass

Number of moles = 50.0 g /235.8 g/mol

Number of moles = 0.21 mol

Now we will compare the moles of Fe₂(CO₃)₃  and CO₂.

                          Fe₂(CO₃)₃         :             CO₂

                              1                    :               3

                            0.21                :            1/3×0.21 = 0.07 mol

Volume of CO₂:

PV = nRT

R = general gas constant = 0.0821 atm.L/mol.K

By putting values,

An unknown organic compound composed of carbon, hydrogen, and oxygen was analyzed and found to be 50.84% C, 8.53% H, and the rest oxygen. What is the empirical formula

Answers

In every 100g of that compund there is 50.84 g of C, 8.53 g H and (100-59.37) g = 40.63 g of O.

Step 1: Convert each element's mass in moles. To do that we need to divide each element's mass by their respective molar mass.

For Carbon.

[tex]C = \frac{50.84}{12} = 4.24 mol [/tex]

For Hydrogen.

[tex]H = \frac{8.53}{1} = 8.53 mol [/tex]

For Oxygen.

[tex]O = \frac{40.63}{16} = 2.54 mol [/tex]

Step 2: Divide each of the numbers by the smallest number.

For Carbon.

[tex]C = \frac{4.24}{2.54} = 1.7 [/tex]

For Hydrogen.

[tex]H = \frac{8.53}{2.54} = 3.36 [/tex]

For Oxygen.

[tex]O = \frac{2.54}{2.54} = 1 [/tex]

Step 3: So the empirical formula will be.

[tex] C_{1.7} H_{3.36} O_1 [/tex]

But using decimal will be messy. So we multiply the numbers by 3. The right empirical formula will be.

[tex] C_{5} H_{10} O_3 [/tex]

The empirical formula of an organic compound that contains 50.84% C, 8.53% H, and the rest oxygen is C₅H₁₀O₃.

First, we have to determine the mass percentage of oxygen, knowing that C, H and O amount to the 100% of the compound.

[tex]C + H + O = 100\%\\O = 100\% - C - H\\O = 100\% - 50.84\% - 8.53\% = 40.63\%[/tex]

Then, we divide each mass percentage by the atomic mass of the element.

[tex]C: 50.84/12.01 = 4.23\\H: 8.53/1.01 = 8.45\\O: 40.63/16.00 = 2.54[/tex]

Afterwards, we divide all the numbers by the smallest one, i.e. 2.54.

[tex]C: 4.23/2.54 = 1.66\\H: 8.45/2.54 = 3.33\\O: 2.54/2.54 = 1[/tex]

Finally, we multiply all the numbers by 3, so that they are all integers.

[tex]C: 1.66 \times 3 \approx 5\\H: 3.33 \times 3 \approx 10\\O: 1 \times 3 = 3[/tex]

The empirical formula of the organic compound is C₅H₁₀O₃.

Write an equation to help you determine the amount of money drake has saved up. ILL GIVE YOU BRAINLYIST ANSWER PLESE Write a class called Date that represents a date consisting of a day, month, and year. A date object should have the following methods: public Date(int day, int month, int year) -- Constructs a new Date object to represent the given date public int getDay() -- returns the day value of this date public int getMonth() -- returns the month value of this date public int getYear() -- returns the year value of this date public void addDays(int days) -- Moves the Date object forward in time by the given number of days public int daysTo(Date other) -- Returns the number of days between this Date and the other Date public boolean isLeapYear() -- Returns true if the year of this Date is a leap year. A leap year occurs when the value of the year is divisible by 4, except when it is divisible by 100 and not 400 (so 1700, 1800, and 1900 are not leap years) public String toString() -- returns a String representation of this date in the form day/month/year Write a program in which to test your class. This program should prompt the user to enter the days, months, and years of two separate dates, and then print out the number of days between these two dates.
