Answer:
oxygen is produced at the anode and hydrogen gas is produced at the cathode
Explanation:
Answer: Mixing vinegar and baking soda initiates a chemical reaction that produces carbon dioxide and water.
Explanation:
Answer:
A. 0.064mol
B. 0.85mol
C. 1500mL
Explanation:
A. Molarity = 0.33M
Volume = 195mL = 195/1000 = 0.195L
Mole =?
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 0.33 x 0.195
Mole = 0.064mol
B. Molarity = 1.7M
Volume = 500mL = 500/1000 = 0.5L
Mole =?
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 1.7 x 0.5
Mole = 0.85mol
C. C1 = 12M
V1 = 50mL
C2 = 0.4M
V2 =?
Using the dilution formula C1V1 = C2V2, we find the volume of the diluted solution as follows:
C1V1 = C2V2
12 x 50 = 0.4 x V2
Divide both side by 0.4
V2 = (12 x 50) /0.4
V2 = 1500mL
