Answer:
K = [H2] [CO] / [HCHO]
Explanation:
HCHO(g) ⇌ H2(g) + CO(g)
We can obtain the expression for the equilibrium constant for the above equation as follow:
Equilibrium constant, K for a given reaction is the ratio of the concentration of the product raised to their coefficient to the concentration of the reactant raised to their coefficient.
Thus, the equilibrium constant, K for the above equation can be written as follow:
K = [H2] [CO] / [HCHO]
Answer:
group 1 - cations charge +1
group 7 - anions charge -1
Explanation:
Group 1 has one valence electron and will lose one electron to complete the octet.
Group 7 has 7 valence electrons and will accept an electron to complete the octet.
