A scientist measures out equal volumes and concentrations of hydrochloric acid and sodium hydroxide solutions. When mixed, these
olasank [31]

Answer:

Neutral solution is formed.

Explanation:

When the hydrochloric acid and sodium hydroxide which is a strong base are combined together, it produces sodium chloride which is a salt and water. This solution is known as Neutral solution because the solution do not have the characteristics or properties of either an acid or a base. If the concentration of one of the reactant is higher as compared to another reactant so the product has the characteristics of that reactant.

What is the order of increasing rate of eusion for the following gases, Ar, CO2, H2, N2?
AVprozaik [17]

Answer:

H2 > N2 > Ar > CO2

Explanation:

Graham's law explains why some gases efuse faster than others. This is due to the difference i their molar mass. Generally; The rate of effusion of gaseous substances is inversely proportional to the square rot of its molar mass.

This means gases with low molar masses would have higher efusion rate compared to gases with higher molar masses.

So now we just need to compare the molar masses of the various gases;

Ar - 39.95

CO2 - 44.01

H2 - 2

N2 - 28.01

To obtain the order in increasing rate, we have to order the gases in decreasing molar mass. This order of increasing rate is given as;

H2 > N2 > Ar > CO2
