Question

Допишите уровнение:1) CH2=CH2+HCL --->2) CH4+ O2 --->3) C6H6+ H2 --->плиз ребят !!!

Answer 1

CH2=CH2+HCL= CH3-CH2Cl
CH4+ O2= CO2+H2O

Answer 2

 
2) 2CH4+ 2O2 = CO2 + 2H2O (остальные хз)
 

Answer 3

Balancing Chemical Equations

Sure, I'd be happy to help you balance these chemical equations!

1) CH2=CH2 + HCl → To balance this equation, we start by counting the atoms of each element on both sides of the equation. We have: - Carbon (C): 2 on the left, 1 on the right - Hydrogen (H): 4 on the left, 1 on the right - Chlorine (Cl): 1 on the right

To balance the equation, we can add a coefficient of 2 in front of HCl to achieve balance: CH2=CH2 + 2HCl →

2) CH4 + O2 → Here, we have: - Carbon (C): 1 on the left - Hydrogen (H): 4 on the left - Oxygen (O): 2 on the right

To balance the equation, we can add a coefficient of 2 in front of CH4 and a coefficient of 2 in front of O2: CH4 + 2O2 → CO2 + 2H2O

3) C6H6 + H2 → For this equation, we have: - Carbon (C): 6 on the left - Hydrogen (H): 6 on the left - No hydrogen on the right

To balance the equation, we can add a coefficient of 3 in front of H2: C6H6 + 3H2 →

I hope this helps! Let me know if you have any other questions.
