Answer:
M = 1.26
Explanation:
Molarity = mole of solution/liters of solution
435mL/1000 = .435L
Plugging in the numbers into the formula, we get:
Molarity = .550 mol/.435L = 1.26 M
Answer:
Solids.
Explanation:
In a solid object, particles are packed tightly together in fixed positions even if in a container.
Answer:
moving across te periodic table electronegativity increases.
Explanation:
as we move across a period the effective nuclear charge increases as the number of protons in nucleus increases. due to increase in effective nuclear charge electronegativity increases

You have OH- conc = </span>2.3 ✕ 10−6 m
From the formula, you can observe the ratio of Cu2+ to OH- is 4 : 6 = 2:3
So, for 2.3 ✕ 10−6 m OH-
[Cu2+] =
