Element X reacts with element Y to give a product containing X 3+ ions and Y 2- ions. (c) What is the formula of the product?

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

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?

Verified step by step guidance

Identify the charges of the ions involved in the compound. Element X forms X^{3+} ions, and element Y forms Y^{2-} ions.

Determine the ratio of X^{3+} ions to Y^{2-} ions needed to balance the overall charge of the compound. The goal is to have a neutral compound.

Use the least common multiple (LCM) of the charges to find the smallest whole number ratio of X and Y that results in a neutral compound. The LCM of 3 and 2 is 6.

Calculate the number of X^{3+} ions needed to reach a total positive charge of +6. This requires 2 X^{3+} ions (2 * 3 = +6).

Calculate the number of Y^{2-} ions needed to reach a total negative charge of -6. This requires 3 Y^{2-} ions (3 * -2 = -6).

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ionic Charges

Ionic charges are the electrical charges that ions carry, determined by the loss or gain of electrons. In this case, element X forms X3+ ions, indicating it has lost three electrons, while element Y forms Y2- ions, meaning it has gained two electrons. Understanding these charges is crucial for determining how ions combine to form neutral compounds.

Chemical Formula

A chemical formula represents the composition of a compound, indicating the types and ratios of atoms present. To derive the formula from the ionic charges, we must balance the total positive and negative charges. This ensures that the resulting compound is electrically neutral, which is a fundamental principle in chemistry.

Criss-Cross Method

The criss-cross method is a technique used to determine the formula of an ionic compound by using the absolute values of the ionic charges. In this method, the charge of one ion becomes the subscript of the other ion. For example, with X3+ and Y2-, we would take the 2 from Y and make it the subscript of X, and the 3 from X as the subscript of Y, leading to the formula XY3.
