Is it acceptable to simply add the partial pressure of each species to determine the total pressure? why or why not?.

Answers

Answer 1
Partial pressure the the amount of pressure exerted from a mixture of gasses. So the total pressure of the solution will be the sum of the partial pressure, even if a constituent has is inert.

What number of moles of O2(g) is required to react with 3.6 mol SO2(g) in the following
reaction?
2SO2(g)+ O2(g) → →2SO3(g)

Answers

Answer:

first balance the equation:

2SO2+O2=2SO3. BALANCED EQUATION

find the ratio:

2:1:2. SO2:O2:SO3

5.0 moles of SO2 React

1/2×5.0 moles=2.5moles of O2 are needed

The 1.8 moles of the oxygen (O₂) gas are required to react with 3.6 mol SO₂(g).

What is the balanced chemical equation?

A chemical equation is a way to represent a chemical reaction in terms of chemical symbols of the reactants and products. The equation in which the number of atoms of chemical substances (reactants and products) is equal on either side of the equation is known as a balanced chemical equation.

Balancing of a chemical equation must follow the law of conservation of mass. The total mass of the elements present on the reactant side must be equal to the total mass of elements present on the product side while obeying this law in a balanced chemical equation.

Given, the chemical equation of the formation of sulphur trioxide is:

2SO₂(g)  + O₂(g)  →  2SO₃(g)

From the above equation, we can say that the two moles of sulphur dioxide react with one mole of oxygen gas to form two moles of sulphur trioxide gas.

3.6 moles of the SO₂(g) react with moles of oxygen gas = 3.6/2 = 1.8 mol

Nitrogen gas and hydrogen gas react to produce ammonia according to the following equation.


N2 + 3H2 → 2NH3


The atomic mass of nitrogen is 14 g/mol. The atomic mass of hydrogen is 1 g/mol. When the reaction produces 68 grams of ammonia, how many grams of nitrogen were present initially?


A 4

B 56 ***

C 12

D 112

Answers

Specific Mass Conversions Quick Check:

It compares the mass of the products to the mass of the reactants.For every 3 moles of hydrogen gas, the reaction produces 2 moles of ammonia.5632 g/mol4

The amount of nitrogen that would produce 68grams of ammonia = 56 g/mol

Calculation of amount of nitrogen

The atomic mass of nitrogen is = 14 g/mol

2 atoms of nitrogen = 2 × 14 = 28 g/mol

The molecular mass of ammonia produced from 28 g/mol of nitrogen = 2(14+ 3)

= 2 × 17

= 34g/ mol

if 28g of Nitrogen = 34g/mol of ammonia

xg of Nitrogen = 68g/mol of ammonia

Make X the subject of formula,

X ,= 28 × 68/34

X = 1904/34

X = 56 g/mol of Nitrogen

Therefore, 56 g/mol of Nitrogen were present initially.

Why do you Think you weight less on Uranus than earth even though it is more massive planet ? 

Answers

Answer:

You would weigh less on Uranus than on Earth because Uranus is far less mass-ive and dense than the Earth. This means that there is less gravity. Therefore, you would weigh less.

Explanation:

Even though Uranus is bigger, it is less massive; that is, there is less mass that makes up the planet. The volume of the planet might be larger, but the actual amount of mass isn't.

By the way, you couldn't stand on Uranus. It's made of gas!

Murcury is the only metal at room temperature. Its density is 13.6g/mL. How many grams of murcury will occupy a volume of 95.8mL? Answer in scientific notation.

Answers

Answer:

The answer is 1.30288 × 10³ g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 95.8mL

density = 13.6g/mL

We have

mass = 13.6 × 95.8 = 1302.88

We have the final answer as

1.30288 × 10³ g

a 26.4 g sample of copper has a specific heat capacity of "0.3845" j/g c°. the copper is heated to 225°c and then cooled to 0°c. how much energy

Answers

Taking into account the definition of calorimetry, the energy released is 2283.93 J.

Calorimetry

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

In this way, between heat and temperature there is a direct proportional relationship. the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where:

Q: the heat exchanged by a body of mass m. c: specific heat substance. ΔT: the temperature variation.

Energy released

In this case, you know:

Q= ?c= 0.3845 [tex]\frac{J}{gC}[/tex]m= 26.4 gΔT= Tfinal - Tinitial= 0°C - 225 °C= -225 C

Replacing in the definition of calorimetry:

Q = 0.3845 [tex]\frac{J}{gC}[/tex]× 26.4 g× (-225 C)

Solving:

Q= -2283.93 J

Finally, the energy released is 2283.93 J.

b
4.8 x 1023 grams

c
30 grams

d
19 grams

Answers

Answer:

m = 19 grams

Explanation:

Given that,

No. of moles, n = 0.8

The molar mass of magnesium, M = 24.305 u

We need to find the mass of 0.80 moles of Mg. We know that given mass to the molar mass is equal to no of moles. Let the mass is m. So,

[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=0.8\times 24.305 \\\\m=19.444\ \text{grams}[/tex]

or

m = 19 grams

So, the mass of 0.8 moles of Mg is 19 grams.

A microwave oven has a power rating of 850 W.
If the microwave oven is turned on for 6 minutes, how much energy will use? Give me the simplest answer possible as for a yr6-8 student to understand.. please..

Answers

Answer:

Explanation:

Before we jump into it, I just want to point out that a microwave oven has two

power ratings.  One is the amount of electrical power it takes from the wall outlet to do its job. The other is the "cooking power" it delivers into the chamber in the form of microwave radiation to heat the meatloaf.  The utility power required from the wall outlet is always more than the cooking power radiated into the chamber.

But we didn't really need to go into all that in order to answer the question.

1 watt = 1 joule per second

1 minute = 60 seconds

(850 watts) x (1 (joule/sec) / watt) x (60sec/min) x (6 minutes) = 306,000 joules

Answers

The change in temperature (in °c) of the copper block placed into the water is 67.7 °C

How to determine the equilibrium temperature Mass copper (M꜀) = 25 gSpecific heat capacity of copper (C꜀) = 0.380 J/gºC Temperature of copper (T꜀) = 88 °CMass of water (Mᵥᵥ) = 500 gTemperature of water (Tᵥᵥ) = 20 °CSpecific heat capacity of the water = 4.184 J/gºC Equilibrium temperature (Tₑ) =?

Heat loss = Heat gain

M꜀C(T꜀ – Tₑ) = MᵥᵥC(Tₑ – Tᵥᵥ)

25 × 0.38 (88 – Tₑ) = 500 × 4.184(Tₑ – 20)

9.5(88 – Tₑ) = 2092(Tₑ – 20)

Clear bracket

836 – 9.5Tₑ = 2092Tₑ – 41840

Collect like terms

836 + 41840 = 2092Tₑ + 9.5Tₑ

42676 = 2101.5Tₑ

Divide both side by 2101.5

Tₑ = 42676 / 2101.5

Tₑ = 20.3 °C
