KBr + H2O = KOH + Br2 + H2
So we know that we need a 2 on the left of kbr so it would equal the right Br.
=2KBr
now put a 2 in front of KOH since we need a 2k on right side
Now we put a 2 infront of H2O which wil make 4 h's and 2 o's
2h2o
now it is balanced
2KBr + 2H2O = 2KOH + Br2 + H2
Answer:
I think it's A
Explanation:
H202 is hydrogen peroxide
H20 is water
Answer:
ust use the equation
M1 X V1 = M2 X V2
where M1 is the initial concentration, V1 the volume of M1, M2 the final concentration and V2 the final volume. Here you are looking for V1 so, first solve for V1 and put in the numbers.
V1 = (M2 X V2)/M1 = (3 X 0.5)/18 = 0.5/6 = 0.083 L or 83 mL
