A small amount wet of hydrogen gas can be prepared by the reaction of zinc with excess hydrochloric acid and trapping the gas pr
dybincka [34]

Answer : The partial pressure of the hydrogen is, 705.9 mmHg

Explanation :

According to the Dalton's law of partial pressure,

P_T=P_{H_2}+P_{H_2O}

where,

P_T = total pressure of the gas = 729.7 mmHg

P_{H_2} = partial pressure of the hydrogen gas = ?

P_{H_2O} = partial pressure of the water = 23.8 mmHg (standard value)

Now put all the given values in the above expression, we get:

729.7mmHg=P_{H_2}+23.8mmHg

P_{H_2}=705.9mmHg

Therefore, the partial pressure of the hydrogen is, 705.9 mmHg

damaskus [11]

Answer:

c.- How much of the reactants are needed and how much product will made.

Explanation:

The moles is the matter unit used in chemistry to simplify  some calculations, instead of using grams. Also the moles are very useful because the chemical reaction can be balanced.

When a Chemical reaction is balanced, then it can be easily to calculate how many moles are necessary to add in a process to obtain a quantity of grams of a product.
