Answers
Step-by-step explanation:
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.
Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
Ionic charges are not yet supported and will be ignored.
Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
Compound states [like (s) (aq) or (g)] are not required.
You can use parenthesis () or brackets [
Answer:
12,8,12
Step-by-step explanation:
Perimeter =40cm
In parallelogram opposite sides are equal
Perimeter of parallelogram = 2*(length of adjacent sides)
Let unknown side be x
40=2*(12+x)
40=24+2x
2x=40-24
2x=16
x=16/2
x=8
The 3 sides are 8,12,8
