Answer:
A product in science is a substance that is formed when two or more chemicals react.
Explanation:
When a chemical reaction takes place, a new substance is often created from the atoms or molecules of the original substances. There are often multiple products formed in a reaction.
K2so4
the oxidation number of sulphur
2[1]+s+4[-2]=0
2+s-8=0
s=-6
10. The first
11. When the prefix “mono” is added that element in the chemical formula is not written with a subscript. If the prefix is greater than one you write a subscript in the formula
Answer:
See explanation
Explanation:
Step 1: Data given
For the reaction aA + bB ⇆ cC + dD
Kc = [C]^c * [D]^d / [A]^a [B]^b
a. SbCl5(g) ⇄ SbCl3(g) + Cl2(g)
Kc = [Cl2]*[SbCl3] / [SbCl5]
b. 2 BrNO(g) ⇄ 2NO(g) + Br2(g)
Kc = [Br2]*[NO]² / [BrNO]²
c. CH4(g) + 2 H2S(g) ⇄ CS2(g) + 4 H2(g)
Kc = [H2]^41 * [CS2] / [H2S]²*[CH4]
d. 2CO(g) + O2(g) ⇄ 2CO2(g)
Kc = [CO2]² / [O2][CO]²
