What is a balanced equation for the neutralization of these two compounds? HCl Ca(OH)2

1 answer:

8 0

In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:

2HCl + Ca(OH)2 = CaCl2 + 2H2O

The empirical formula of styrene is CH; its molar mass is 104.1 g/mol. What is the molecular formula of styrene

frez [133]

The atomic mass of carbon is 12.011 g/mol.
The atomic mass of hydrogen is 1.00794 g/mol.

This means the molar mass of CH is

$12.011+1.00794=13.01894 \text{ g/mol}$

Dividing the given molar mass by this, $\frac{104.1}{13.01894} \approx 8$

This means the molecular formula is $\boxed{\text{C}_{8}\text{H}_{8}}$
