HELP Consider this equation...
Mashcka [7]

Answer:

it is not correct I have an answer for ''why''

Explanation:

You need to balance it

s= 2

0=2

S+30•2 --------> SO•3

2 2 2 2

S +3O•2-------->SO•2......MULTIPLY

2 4 2 4......LCM IS 4

2 1 2 1....DIVIDE BY 4

SO NOW WE GOT THE BALANCE NO. WE CAN PUT IT IN THE EQUATIONS.

2S+3O•2 -----> 2SO•3

now you can check the both sides its balances the correct answer is this

The molar mass of vitamin A (C20H30O).
vivado [14]
Molar mass of C:  12.011 g/mol
The equation says C20, which means there are 20 carbon atoms in each molecule of Vitamin A.  So, we multiply 12.011 by 20 to get 240.22 g/mol carbon.

Molar mass of H:  1.0079 g/mol
The equation says C30, which means there are 30 hydrogen atoms in each molecule of Vitamin A. So, we multiply 1.0079 by 30 to get 30.237 g/mol hydrogen.

Molar mass of O: 15.999 g/mol
The equation says O without a number, which means there is only one oxygen atom in each molecule of Vitamin A.  So, we leave O at 15.999 g/mol.

Then, just add it up:
240.22 g/mol C + 30.237 g/mol H + 15.999 g/mol O = 286.456 g/mol C20H30O

So, the molar mass of Vitamin A, C20H30O, is approximately 286.5 g/mol.
