Answer:
22.5
Explanation:
all you have to do is take the number of moles of al and multiply them by sulfuric acids mole ratio as given in the equation (3), then divide by aluminums mole ratio number (2). then you will have moles of sulfuric acid.
*note: this only works if you are going moles to moles, if you are converting to anything else, this will NOT work*
if you have any questions leave them in the comments and i will try to answer them, if this helped, pls give a brainly
Explanation:
Yes, the equation is balanced. There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation.
Answer: 3.0 moles of water 
are needed to react with a mole of 3.0 of Na
Explanation:
The balanced chemical reaction of sodium with water is as follows:
According to stoichiometry:
2 moles of sodium 
reacts with = 2 moles of water
Thus 3.0 moles of sodium reacts with = 
moles of water
3.0 moles of water are needed to react with a mole of 3.0 of Na
