Answer:
A bowling ball is a ball that is used in the game of bowling, where you roll the ball down an aisle and try to knock down as many pins as you can.
Answer:
155 kJ of energy will be released.
Explanation:
The 
(
in some textbooks) here stands for standard enthalpy change per mole reaction. To find the amount of energy released in this reaction, start by finding the number of moles of this reaction that will take place.
How many <em>moles</em> of atoms in 4.72 grams of carbon?
Relative atomic mass data from a modern periodic table:
.
The coefficient of carbon in the equation is one. In other words, each mole of the reaction will consume one mole of carbon. Oxygen is in excess. As a result, 
of carbon will support of the reaction.
How much energy will be released?
The 
value here is negative. But don't panic. is the same as the chemical potential energy of the reactants minus the products in one mole of the reaction. 
means that the chemical potential energy drops by 
during each mole of the reaction (with the coefficients as-is.) Those energy difference will be released as heat. In other words, one mole of the reaction will release 
of energy.
The 4.72 grams of carbon will support of this reaction. How much heat will that of reaction release?
.
As a side note, the mass of carbon 4.72 grams is the least significant data in this question. There are three significant figures in this value. As a result, keep more than three significant figures in calculations but round the final result to three significant figures.
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
<u>Explanation</u>:
- Wind flow towards the low pressure and the air rises in the atmosphere. As the air increases, the water vapor within it solidifies, forming clouds and undergo precipitation. Low pressure formed in the center areas.
- The atmospheric circulations of air up and down in a low-pressure area remove a small amount of atmosphere. This usually happens between warm and cold air masses by flowing air which tries to reduce the contrast of temperature.
Answer:
1000 meters
Measure of Lengths
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters = 1 decimeter (dm) = 100 millimeters
100 centimeter = 1 meter (m) = 1,000 millimeters
1000 meters = 1 kilometer (km)

Hope this helps :)
