First, we have to find the chemical formula for zinc ion and phosphate ion.
Zinc ion is a cation, and its formula is Zn^2+,
This is because zinc atom requires 2 outer shell electrons to be removed in order to become stable.
On the other hand, phosphate ion is a anion, and its formula is PO4^3-.
In order to find the chemical formula of this ionic bond, we need to make sure their charges are balanced.
To do this, take 2+ and 3-, their least common multiple is 6, so in order to turn both charges into 6+ and 6-, we need to determine how many of that ion is needed.
So to make 2+ to 6+, we need 3 zinc ions ( +2 x 3 = 6).
And to make 3- to 6-, we need 2 phosphate ions (-3 x 2 = - 6).
Now we can just combine the chemical formulas with the number of that ion needed (you can ignore the charge)
Therefore, your answer should be Zn3(PO4)2.
Answer:
0.713atm for CO and 0.287atm for CO₂
Explanation:
Based on the reaction:
FeO(s) + CO(g) ⇋ Fe(s) + CO₂(g)
Kp is defined as:
= 0.403
When 1.00 atm of CO react with an excess of FeO, the pressures in equilibrium are:
PCO = 1.00atm - x
PCO₂ = x
<em>Where x represents the reaction coordinate.</em>
Replacing in Kp expression:
0.403 - 0.403x = x
0.403 = 1.403x
0.287atm = x
Thus, pressures in equilibrium are:
PCO = 1.00atm - x = <em>0.713atm</em>
PCO₂ = x = <em>0.287atm</em>
