Answer:
C6H6
Explanation:
C : 60.0 g*1 mol/12 .01g = 5.00 mol
H: 5.05 g * 1 mol/1.01 g= 5.10 mol
C:H = 5.00 mol : 5.10 mol = 1:1
CH is an empirical formula
Molar mass (12.01 +1.01)=13.02 g/mol
78.12g/mol /13.02 g/mol =6
Molecular formula is the empirical that was taken 6 times (CH)6 = C6H6
2 moles of sodium hydroxide will be needed.
<h3><u>Explanation</u>:</h3>
Sodium hydroxide is a compound which is a base and nitric acid is the acid. The formula of the nitric acid is HNO3 and that of sodium hydroxide is NaOH.
The reaction between them are
NaOH +HNO3 =NaNO3 +H2O.
So here we can see that 1 mole of sodium hydroxide reacts with 1 mole of nitric acid to produce 1 mole of sodium nitrate and 1 mole of water.
So for 2 moles of nitric acid, 2 moles of sodium hydroxide will be required.
Answer:
I'd say Water
Explanation:
The plant absorbs more water through the roots not sure if i'm correct.

It can be shown that matter is neither created nor destroyed in a chemical reaction by taking a critical look at the each atom in both sides of the reaction (reactant and product sides).
1 atom of Mg started the reaction and 1 atom is also present in the products.
8 atoms of O are present in the reactants and 8 is also present in the products.
4 H atoms are present in the reactants and 4 are also present in the products.
2 N atoms are present in the reactants and 2 are also in the products.
In other words, the total number of each atom that is present in the reactants are also present in the product. Nothing has been lost during the reaction, although, the forms of each atom might have changed.
