A green box contains a blue box and a pink box. The blue box contains C H subscript 4 + 2 O subscript 2. An arrow then leads in the green box to the pink box, which says C O subscript 2 + 2 H subscript 2 O. Lines lead from labels to parts of the boxes. Label A leads to the beginning of the green box. Label B leads to the + in the blue box. Label C leads to the arrow. Label D leads to the 2 in 2 H subscript 2 O. Label E leads to the end of the pink box. Identify each part of this chemical equation that describes the burning of methane and oxygen.
FYI ; This is also the answer

B (blue box):
✔ reactants

D (number):
✔ coefficient

E (purple box):
✔ products

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.
