Please help! 1. Potassium forms ions with a charge of +1(K^+). Iodine forms ions with a charge of -1. Selenium forms ions with a charge of -2 (Se^2-). Imagine that potassium ions and selenide ions combine to form potassium selenide. What Numbers would be in the place of X and Y in: KxSeY
(Use the number 1 even if it’s not strictly necessary)
X = ?
Y = ?

2. Calcium forms ion with a charge of +2. Iodine forms with a charge of -1.

Which of the following represents and ionic compound composed of Calcium and Iodine ions?

A) CaI2
B) CaI
C)Ca2I
D)2CaI

answer; natural resources;

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
