Endothermic reactions. These are reactionsthat take in energy from the surroundings. The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to get colder
Answer: There are 576.46 number of grams present in 16.95 mol hydrogen peroxide
.
Explanation:
Number of moles is defined as the mass of substance divided by its molar mass.
The molar mass of
is 34.01 g/mol. Hence, mass of hydrogen peroxide present in 16.95 moles is calculated as follows.

Thus, we can conclude that there are 576.46 number of grams present in 16.95 mol hydrogen peroxide
.
Answer:
The answer is below
Explanation:
one gallon of gasoline produces 9.50 kg of carbon.
The total number of cars = 40 million
Distance covered by each car = 7930 miles
Consumption rate of the cars per miles traveled is 23.6 miles per gallon.
Hence the annual gasoline consumption by all the cars in the United States of America = (total number of cars × Distance covered by each car) ÷ Consumption rate of the cars per miles
annual gasoline consumption by all the cars = (40000000 × 7930 miles) ÷ 23.6 miles/gallon = `1.344067797 × 10¹⁰ gallons
1.344067797 × 10¹⁰ gallons =

The answer is A. Gravity
The gravitioal force that an object exerted will increase as the object is increasing in sizre.
Which means that if object A has two-times more mass than object B, Object A will has twice as much gravitational pull if compared to object B.
