Balance this equations pH3+O2=P4O10+H2O

Because there are 4 P on the right side, we have to put a coefficient of 4 on the left to balance out the P.

This would give us 12 H on the left and 2 H on the right, so we have to put a 6 on the right to balance out the H.

Now we have 16 O on the left and 2 on the right, so a coefficient of 8 is required to balance out the O.

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.
