Element X reacts with element Y to give a product containing X³⁺ ions and Y^2- ions. (c) What is the formula of the product?

Video transcript

Hello. In this problem we are told to form a product consisting of a two plus lines and be three minus signs. Element A reacts with element B. We are asked to determine the formula of the product so we can make use of the criss Cross method. We first write the formula for our cat line, followed by that for an online Using the criss Cross method. Then the superscripts become sub scripts. And when we check the charges they should balance. So three times plus two plus six, two times minus three is minus six. So this sums to zero. Then writing formula, eliminating all of our work. We have a three B two. We want to ensure then that this is the simplest formula. We can't factor anything out of our sub scripts recall. Then formula compounds should be the smallest ratio of caddies to analyze which it is in this case. So this is our formula for a product and this corresponds to answer a thanks for watching. Hope this helps
