The partial pressure of Ne is 1.06 atm. The answer is a. 1.1 atm
Answer:
[Cl⁻] = 0.016M
Explanation:
First of all, we determine the reaction:
Pb(NO₃)₂ (aq) + MgCl₂ (aq) → PbCl₂ (s) ↓ + Mg(NO₃)₂(aq)
This is a solubility equilibrium, where you have a precipitate formed, lead(II) chloride. This salt can be dissociated as:
PbCl₂(s) ⇄ Pb²⁺ (aq) + 2Cl⁻ (aq) Kps
Initial x
React s
Eq x - s s 2s
As this is an equilibrium, the Kps works as the constant (Solubility product):
Kps = s . (2s)²
Kps = 4s³ = 1.7ₓ10⁻⁵
4s³ = 1.7ₓ10⁻⁵
s = ∛(1.7ₓ10⁻⁵ . 1/4)
s = 0.016 M
Answer:
Tbh i rlly dont think that many will. Most may succeed in doing so. But i mean come on its 2020 anything can happen.
Explanation:
ANSWER: A
EXPLANATION:
THE FORMULA FOR DENSITY IS MASS DIVIDED BY VOLUME.
D= M/V
So divide the mass by the volume.
For A, 122 divided by 10.5 is 11.62
For B, 132 divided by 14.2 is 9.295
For C, 115 divided by 16.1 is 7.143
For D, 126 divided by 12.7 is 9.921
A IS THE ANSWER BECAUSE ITS THE LARGEST AMOUNG THE OTHERS.
Chemical reactions are the result of an atom attempting <span>to rearrange its configuration to result in a complete outer shell or have a stable octet. </span>
