The specific heat means the heat absorbed when 1 g of the compound increase 1 ℃. So the specific heat is 41.71/(18.69*17)=0.131 J/(g*k).
Carbonate compounds have a negative valency (because they contain oxygen), so NaCO3 has a negative valency (it’s a negatively-charged ion) which makes it basic or alkaline.
Answer:
469 gallons
Explanation:
From the question given, we were told that:
For every 32 miles, 1 gallon of gasoline is consumed.
With the above information, we can obtain the number of gallon of gasoline consumed by a car per year i.e 15000 miles
This is illustrated below:
If 32 miles consumed 1 gallon of gasoline,
Therefore, 15000 miles will consume = 15000/32 ≈ 469 gallons of gasoline.
Therefore, 469 gallons of gasoline is consumed by the average car each year
