The controlled variable is the variable that remains the same throughout the whole experiment. Here, the warm water and the same dishes are the same throughout the whole experiment- so they are the controls
Answer:
LiOH+CH3COOH=C2H3LiO2+H2O balanced equation
Explanation:
lithium hydroxide-> LiOH
hydrogen acetate->CH3COOH
lithium acetate->C2H3LiO2
water->H2O
LiOH+CH3COOH=C2H3LiO2+H2O
Li=1,O=3,H=5,C=2 --> Li=1,O=3,H=5,C=2
the two sides have same numbers so it is balanced.
