Answer:
#2: They break down quicker than stable isotopes. - im not sure
Explanation:
Answer
is: The molar solubility of calcium phosphate is 108s⁵ = Ksp.
<span>
Balanced chemical reaction: Ca</span>₃(PO₄)₂(s) → 3Ca²⁺(aq) + 2PO₄³⁻(aq).<span>
[Ca²</span>⁺] =
3s(Ca₃(PO₄)₂) =
3s.<span>
[PO</span>₄³⁻] = 2s.<span>
Ksp = [Ca²</span>⁺]³ · [PO₄³⁻]².<span>
Ksp = (3s)³ · (2s)².
Ksp = 108s</span>⁵.
s = ⁵√(Ksp ÷ 108).
Answer:
<em>D. Gas X has a lower density and effuses faster than Gas Y.</em>
Explanation:
I took the test.
- Lower Density = effuse/ diffuse faster
- Lower Molar Mass = effuse/ diffuse faster
Answer:
the answer is H ..............
Answer:
<h2>The answer is 2.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 15.9 g
volume = final volume of water - initial volume of water
volume = 56.3 - 50 = 6.3 mL
It's density is
We have the final answer as
<h3>2.52 g/mL</h3>
Hope this helps you
