Answer:
Explanation:
I’m 99.9% sure that it’s an element because it can’t be broken down any more than it already is.
Mass of Ni = 0.015 mol Ni × (58.693 g Ni/1 mol Ni) = 0.88 g Ni
Answer:
PCl₃
Explanation:
To determine the empirical formula of a compound, we need to follow a series of steps.
Step 1: Divide each percent composition by the atomic mass of the element
P: 22.6/30.97 = 0.729
Cl: 77.4/35.45 = 2.18
Step 2: Divide all the numbers by the smallest one, i.e. 0.729
P: 0.729/0.729 = 1
Cl: 2.18/0.729 ≈ 3
The empirical formula of the compound is PCl₃.
Answer:
Cl
Explanation:
Electronegativity increases as you move up and to the right of the periodic table. For example, Florine is the most electronegative element.
