Can someone please help me out, I need to do this asap. Tired of bots responding my questions and would have to report it instantly

Solution given:

Required reaction is:

2H2+O2➔2H2O

now

10.

oxygen have 16 amu than total mass in the left side of oxygen is:

16×2=32 amu of Oxygen

11.

total mass of Oxygen in product side is;

16×2=32 amu of Oxygen

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
