Answer:
0.02 moles.
Explanation:
volume of H₂ gas at R.T.P = 480 cm³
Where
R.T.P = room temperature and pressure
molar volume of gas at = 24000 cm³
no. of moles of hydrogen = ?
Solution:
formula Used
no. of moles = volume of gas / molar volume
put values in above equation
no. of moles = 480 cm³ / 24000 cm³/mol
no. of moles = 0.02 mol
So,
no. of moles of hydrogen in 480 cm³ is 0.02 moles.

<h3>What are the products in a reaction?</h3>
This concept refers to the substances obtained at the end of the reaction.
<h3>What does it mean to balance an equation?</h3>
It means to make sure there are the same molecules in the reactants and products.
<h3>What are the products in this reaction?</h3>
- Al + H2SO4 = Al2 (SO4)3 + H2
- Al2 (SO4)3 = Aluminium sulfate
- H = Hydrogen
<h3>What is the balanced equation?</h3>
2Al + 3H2SO4 = Al2 (SO4)3 + 3H2

Answer:
d) additional heat alters the vicosity and the surface tension of the liquid which raises the vapor pressure and increases the boiling point which is why you must continually heat the solution
