125 cm3 of a solution contains 0.25 moles of the solute. What is the concentration of the solution?

Answers

Answer 1
Answer:

Answer:

Explanation:

125 cm3 -> 0.125 L

M = no. mole / volume (L)

M = 0.25 / 0.125 = 2 M

__________ is one of many factors that can determine the rate of alcohol absorption.

Answers

Food consumption affects the rate of alcohol absorption in the bloodstream.

Explanation:

The type of food and therefore the amount of food that is a gift in your epithelial duct once you consume alcohol have the foremost direct impact on the speed of alcohol absorption.

When you consume alcohol on the associate empty abdomen, the alcohol is sometimes absorbed within the blood among fifteen minutes to two-and-a-half hours. If you have got a moderate quantity of food in your abdomen once you drink, that speed slows all the way down to thirty minutes to a few hours. If you’re drinking on a full abdomen, alcohol absorption ranges from 3 to 6 hours.

Answer: The answer is C. Food.

The equation shows the reaction between zinc metal and hydrochloric acid.Zn(s) + 2HCl(aq) mc014-1.jpg ZnCl2(aq) + H2(g)


What is the theoretical yield of hydrogen gas if 5.00 mol of zinc are added to an excess of hydrochloric acid?
5.05 g
10.1 g
182 g
682 g

Answers

The balanced chemical reaction is written as:

Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)

We are given the amount of the reactant zinc to be used in the reaction This amount would be the starting point for the calculation. It is as follows:

5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) (2.02 g H2 / 1 mol H2 ) = 10.1 g H2

Therefore, the correct answer is the second option.

Answer:

B. 10.1g

What is the vapor pressure of carbon disulfide at its normal boiling point?

Answers

Carbon disulfide has a vapor pressure of 363 torr at 25 °C and a normal boiling point of 46.3 °C.

What is Vapor pressure?

Vapor pressure or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is an indication of the thermodynamic tendency of a liquid to evaporate.

It is the pressure at which a liquid and its vapor are in equilibrium at a given temperature where the vapor is said to "push" against the atmosphere, so the higher the vapor pressure the faster the liquid evaporates.

The vapor pressure is different for different compounds like for Carbon disulfide the vapor pressure is 363 torr at 25 °C.

Thus, Carbon disulfide has a vapor pressure of 363 torr at 25 °C and a normal boiling point of 46.3 °C.

When a neutral atom undergoes oxidation, the atom’s oxidation state(1) decreases as it gains electrons(2) decreases as it loses electrons(3) increases as it gains electrons(4) increases as it loses electrons

Answers

When a neutral atom undergoes oxidation, the atom's oxidation state increases at it lose electrons. 
The acronym "OILRIG" can be used to remember this: Oxidation is Losing electrons, Reduction is Gaining electrons. Therefore, when an atom undergoes oxidation, it loses electrons. This makes its net charge more positive, so its oxidation state increases.
This best fits choice (4).
