Explanation:
just took the quiz in case anyone needs it
The concentration of Ca2+ ions is half that of the Cl- ions.
Find moles, using molar mass:
<span>2.71 g ZnCl2 @ 136.32 g ZnCl2 / mole = 0.01988 moles Zn+2 </span>
<span>find moles </span>
<span>0.350.L @ 0.0560 moles / Litre = 0.0196 moles (CO3)-2 </span>
<span>by the equation </span>
<span>Zn+2 & CO3)-2 --> ZnCO3 (s) </span>
<span>0.0196 moles (CO3)-2 reacts with an equal 0.0196 moles Zn+2 , </span>
<span>0.01988 moles Zn+2 - 0.0196 moles Zn+2 reacted = 0.00028 moles Zn+2 remain </span>
<span>find molarity remaining </span>
<span>0.00028 moles Zn+2 / 0.350 litres = 0.000799 Molar </span>
<span>your answer, to 1 sig fig is </span>
<span>0.0008 Molar Zn+2 </span>
<span>aka </span>
<span>0.8 milliMolar Zn+2 </span>

that I was going to be a salted water and the kids and a half hours to go to misdeed I have to go back and I don't know if you don't want you so bad that you have to go back and I don't know if you don't have any money on me to get a new for me and I don't think so too baby and you are so sweet to see the new
Answer:
Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp
Explanation:
The reaction is:
2NO + 2H₂ → N₂ + 2H₂O
The expression for Kp (pressure equilibrium constant) would be:
Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²
There is another expression for Kp, where you work with Kc (equilibrium constant)
Kp = Kc (R.T)^Δn
where R is the Ideal Gases constant
T° is absolute temperature
Δn = moles of gases formed - moles of gases, I had initially
