Gatorade has the conductivity of 3296 µS, Powerade has 4502 µS, and Vitamin Water is 657 µS. What does this data tell you about the dissolved ions in these solutions?

Answers

Answer 1

Answer:

Powerade has the most dissolved ions, followed by Gatorade and lastly vitamin water

Explanation:

How conductive a certain solution is, is based on the kind of ions that are present or dissolved in the solution. Hence, we have it that, the higher the concentration of the ions that are present in a solution, the better it will conduct.

There is thus, a direct relationship between what is dissolved or the kind of present ions and how conductive the solution is.

A solution with more dissolved ions is a better conductor of electricity and thus has a conductivity value that is higher

Thus, we can conclude that Powerade has more dissolved ions, Gatorade has less and Vitamin water has the least

On increasing which of the following factors, decreases the extent of physisorption? Surface area of the adsorbent Critical temperature of the adsorbate Concentration of adsorbate Temperature at which adsorption is carried out

Answers

Answer: On increasing temperature at which adsorption is carried out decreases the extent of physisorption.

Explanation:

An adsorption where molecules of the adsorbate are placed or held on the surface of adsorbent by Vander waals forces is called physisorption.

There is basically physical bonding between the molecules of gas to the surface of a solid or liquid.

Physisorption is reversible in nature and occurs at low temperatures.

It is not specific in nature which means that all gases are adsorbed on the surface of every solid substance to some extent.

Thus, we can conclude that on increasing temperature at which adsorption is carried out decreases the extent of physisorption.

Answers

Answer:

CH3OH(s)<CH3OH(l)<CH3OH(g)<CH3CH2OH(g)

Explanation:

Entropy is defined as the degree of disorderliness of a system. The more orderly a system is, the more its entropy tends to zero.

Hence solid particles have the least entropy because solid particles do not translate. The entropy of liquid particles is greater than that of solid particles since liquid particles can translate. Gas particles have the highest entropy because gas particles move at a very high velocity owing to minimal intermolecular interaction.

Also, the heavier the molecules of a substance, the larger its molar entropy therefore, CH3CH2OH(g) exhibits the greatest entropy.

In the second question the 2 belongs to Y as we all know Sodium is atomic number 11 with a valence of one, so they exchanged valence.

When Y2 reacts with chlorine with atomic number 17 and valence 1,they exchange valencies making it YCl2.

Equal mases of ethane and hydrogen are mixed in an empty container at 25 degree celcius.The fraction of the total pressure exerted by hydrogen is

Answers

Answer:

15/16

Explanation:

We need to find the number of moles of hydrogen and number of moles of ethane present.

Since we have the same mass, m for both substances, the number of moles of hydrogen, n = m/M where M = molar mass of hydrogen molecule

Since hydrogen is H₂, M = 2 × 1 g/mol = 2 × 1 g/mol = 2 mol.

n = m/M

n = m/2

Also, number of moles of ethane, n' = m/M' where M' = molar mass of ethane.

Since ethane is C₂H₆, M' = 2 × 12 g/mol + 6 × 1 g/mol = 24 g/mol + 6 g/mol = 30 g/mol

n' = m/M'

n' = m/30

The total number of moles of gas present is thus n" = n + n' = m/2 + m/30 = (15m + m)/30 = 16m/30

The mole fraction of hydrogen is thus number of moles of hydrogen/total number of moles = n/n" = m/2 ÷ 16m/30 = m/2 × 30/16m = 15/16

Also, since the partial pressure due to hydrogen, P = mole fraction × total pressure, P'

P/P' = mole fraction = 15/16

So, The fraction of the total pressure exerted by hydrogen is 15/16

Which of the following is an example of commensalism?

Answers

Answer: A tick on a deer

Explanation:

because commensalism is a type of symbiotic relationship in which one species benefits, while the other species is neither harmed nor helped

please put brainlest for me if you found this helpful

An example of commensalism is tick on a deer. Therefore, option A is correct.

What is commensalism ?

Another sort of symbiotic interaction is commensalism, in which one organism benefits and the other does not in any way suffer. Golden jackals will pursue tigers as they hunt in order to consume the tigers' leftovers.

The term "commensalism" is derived from the word "commensal," which in human social interaction refers to "eating at the same table," and which itself is derived through French from the Medieval Latin term "commensalis," which refers to "sharing a table," from the prefix com-, which means "together," and mensa, which refers to "table" or "meal."

The simplest definition of commensalism is that it is a form of symbiosis in which one organism gains while the other neither gains nor suffers harm. The three primary forms of commensalism are phoresy, metabiosis, and inquilinism.

Thus, option A is correct.

Which is a property of all acids?

C. They contain H3O^+ ions.
D. They increase the H^+ concentration in solution.​

Answers

D , for example HCl consists of H+ and Cl- ions

Acids increase the [tex]H^+[/tex] concentration in solution. Therefore, the correct option is D.

One of their essential characteristics is the ability of all acids to increase the concentration of H+ ions (protons) in a solution. Acids are chemicals that when dissolved in water add protons to the solution. As a result of this proton donation, the amount of [tex]H^+[/tex]ions in the solution increases, thereby lowering the pH. It is important to remember that not all acids contain[tex]H_3O^+[/tex] ions directly; Instead, [tex]H^+[/tex] ions can react with water molecules to generate [tex]H_3O^+[/tex] ions (hydronium ions).

Given that the acceleration due to gravity is 10N/Kg, calculate the weight of the
Mass (Show all you're working)​

Answers

Answer:

Weight = 500 Newton

Explanation:

Given the following data;

Acceleration due to gravity = 10N/Kg

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

[tex] Weight = mg [/tex]

Where;

m is the mass of the object.g is the acceleration due to gravity.

Note: In order to calculate the weight of a mass, it's required that the mass of an object or body is given.

However, in this particular question it was omitted in error and as such i would assume a value.

Let mass, m = 50 kg

Substituting into the formula, we have;

[tex] Weight = 50 * 10 [/tex]

Weight = 500 Newton

How many moles of NaOH are present in 22.0 mL of 0.140 M NaOH?

Answers

Answer:

Mole of NaOH = 0.00308 mole

Explanation:

From the question given above, the following data were obtained:

Volume = 22 mL

Molarity = 0.140 M

Mole of NaOH =?

Next, we shall convert 22 mL to L. This can be obtained as follow:

1000 mL = 1 L

Therefore,

22 mL = 22 mL × 1 L / 1000 mL

22 mL = 0.022 L

Finally, we shall determine the number of mole of NaOH in the solution. This can be obtained as shown below:

Volume = 0.022 L

Molarity = 0.140 M

Mole of NaOH =?

Molarity = mole / Volume

0.140 = Mole of NaOH / 0.022

Cross multiply

Mole of NaOH = 0.140 × 0.022

Mole of NaOH = 0.00308 mole

Thus, 0.00308 mole of NaOH is present in the solution.

calculate the volume of a 3.0 mol of oxygen, b 50.0g of hydrogen cloride gas at STP(molar volume of gas is 22.4dm³,molar mass of Hcl=36.5g)​

Answers

Answer:

98L is the volume of the gas

Explanation:

To solve this question we need to find  the moles of O2 + moles HCl. With these moles and PV = nRT we can find the volume as follows:

Moles O2: 3.0mol

Moles HCl:

50.0g * (1mol/36.5g) = 1.37 moles HCl

Total moles:

3.0mol O2 + 1.37 mol HCl = 4.37 moles

PV = nRT

V = nRT/P

Where V is volume in L, n are moles = 4.37mol, R is gas constant = 0.082atmL/molK, T is absolute temperature = 273.15K at STP, P = 1atm at STP

V = 4.37mol*0.082atmL/molK*273.15K / 1atm

V = 98L is the volume of the gas

How many moles are in 89 grams of KCI

Answers

Answer:

The number of moles in 89 grams of KCl is approximately 1.193 moles

Explanation:

A mole of an element or compound, is the quantity of the element or compound that contains 6.022 × 10²³ molecules of the element or compound, such that the molar mass of one mole is dependent on the mass of each molecule of the element or compound that make up the 6.022 × 10²³ particles

The given parameters are;

The mass of the KCl = 89 grams

The Molar mass, MW, of potassium, K = 39.1 g/mole

The Molar mass, MW, of chlorine, Cl = 35.5 g/mole

Therefore, given that KCl, has one K and one Cl, per mole, we have;

The Molar mass, MW, of potassium chloride, KCl = (39.1 + 35.5) g/mole = 74.6 g/mole

[tex]The \ number \ of \ moles, n=\dfrac{Mass}{Molar \ mass, MW}[/tex]

Therefore, the number of moles of KCl in 89 g, 'n' is given as follows;

n = (89 g)/(74.6 g/mole) ≈ 1.193 moles

The number of moles in 89 grams of KCl, n ≈ 1.193 moles.

Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.

Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.

They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable

Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .

Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.
