Answer: 345,000 calories
Explanation:
Calories in food such as candy bars refer to the amount of energy that the food has. Calories are also called Kilocalories because they are the equivalent of 1,000 calories.
If the candy bar contained 345 calories therefore, and 1 Calorie is 1,000 calories, the calories in the candy bar are:
= 345 * 1,000
= 345,000 calories

Answer: D. an open series circuit
Answer:
0.00375 moles OF KHP
Explanation:
Equation of reaction of NaOH and KHP :
KHC₈H₄ O₄(aq) + NaOH(aq) → NaKC₈H₄O₄(aq) + H₂O(l)
the reaction required 25ml
Molarity = no of mole / volume in liters
no of moles = Molarity × volume in liters
no of moles of NaOH = 0.150 × (25/1000) = 0.00375 moles
using the balanced equation above
1 mole of NaOH requires 1 mole of KHP
therefore
0.00375 mole of NaOH will require 0.00375 mole KHP.
