Please Help!! To investigate a possible relationship between two factors, such as acidity and solubility, you must first identify the variables involved in the experiment. Identify the independent variable, the dependent variable, and any possible confounding variables within this experiment. PLEASE HURRY

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
