The empirical formula of styrene is CH; its molar mass is 104.1 g/mol. What is the molecular formula of styrene?
Natalija [7]
You got the answer correct. If you would double check
given:C (12 g/mol) H (1 g/mol). 

12(8) + 1(8) = 104 g/mol

and for C2H4
12(2)+1(4) = 28g/mol

Also, chemical formula of styrene is<span> C6H5CH=CH2.</span>

aliya0001 [1]

Answer : The correct option is, (B)

Explanation :

Balance equation : Balanced equation are those equation in which the number of atoms of each element and the total charge must be same on products side and reactants side.

In the given options, only option (B) equation has correct formula and also a balanced equation.

2Be+O_2\rightarrow 2BeO

while the other options has incorrect formulas and also an unbalanced equations.

The correct equation for option A is, CaCO_3\rightarrow CaO+CO_2

The correct equation for option C is, 2Mg+O_2\rightarrow 2MgO

The correct equation for option D is, KCl+HNO_3\rightarrow HCl+KNO_3

Hence, the correct answer is, (B) 2Be+O_2\rightarrow 2BeO
