Answer:
11.99
% ≅ 12.0%.
Explanation:
∵ mass % = [mass of solute/mass of solution] x 100.
mass of solute (CaCl₂) = 8.87 g & mass of solution = 8.87 g + 65.1 g = 73.97 g.
<em>∴ mass % of (CaCl₂) = [mass of solute/mass of solution] x 100 </em>= (
8.87 g/ 73.97 g) x 100 = <em>11.99
% ≅ 12.0%.</em>
Answer:
d. Cl2
sorry if I'm wrong
Cl2, as shown in the picture should have electrons in both the atoms but, in the question, the electrons are only in one of the atoms.
hope it helps :)
Answer:
The answer is B. Limiting factors can lower birth rates, increase death rates.
Answer:
A = Metallic Bond
B = Strong bonding, strong conductor, high melting and boiling points
Explanation:
Since the bond is between two metals (located in groups 11 and 12), they would experience metallic bonding. Metallically bonded molecules have high melting and boiling points due to the strength of the metallic bond. They also experience strong electrical current due to the there delocalized electrons.
