Question

Imagine a made-up polyatomic ion named Paramangate. (No, this ion doesn't really exist, so you can't look this one up). Sodium Paramangate has the formula NazCsH10O_3.

a. What is the formula for paramangate? You must include the charge.
b. Write both the formula and the name for the compound formed when Cu_2+ combines, with paramangate?

Answer 1

The formula for the imaginary polyatomic ion paramangate is CsH10O32-. When combined with Copper (Cu2+), the compound's formula is Cu(CsH10O3)2, named Copper Paramangate.

Step-by-step explanation:

To determine the formula for the made-up polyatomic ion paramangate, we look at the given compound Sodium Paramangate with the formula Na2CsH10O3. Since sodium (Na) forms a 1+ cation, and there are two sodium ions present, paramangate must have an overall charge of 2- to balance the charge of two Na+ ions, making the formula for paramangate CsH10O32-.

When Copper (Cu2+) combines with paramangate, Cu2+ needs two paramagnet ions to balance the 2+ charge. As per the convention, the polyatomic ion is enclosed in parentheses with a subscript to indicate the number of units. Hence, the formula for the compound is Cu(CsH10O3)2 and the name of the ionic compound follows the convention of cation first, then anion, resulting in the name Copper Paramangate.
