Once the following equation is balanced with the smallest set of whole number coefficients, what is the sum of the coefficients? (don't forget to include coefficients of one.) al + h2so4 → al2(so4)3 + h2

9

Explanation:

To balance the equation, we need to supply the number of missing coefficients.

There are 2 moles of aluminium on the right hand side, so automatically we need to multiply the number of moles of aluminium by 2 on the left hand side.

There are 3 sulphate ions on the right hand side so we need to multiply the number on the left by 3.

And lastly since we have 6 hydrogen molecules on the left hand side now, we need to multiply the hydrogen on the right hand side by 3 to give 6

The set of coefficients = 2 3 1 3

Adding all thus yields 9

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.
