<u>D</u><u>.</u><u> </u><u>Noble</u><u> </u><u>Gases</u><u> </u>
- <u>Th</u><u>e </u><u>noble</u><u> </u><u>gasses</u><u> </u><u>are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element.</u>

trust me i used to so this in middle school
Gases, fluids, and
other solids in contact with a moving object will produce heat due to friction.
The contact between molecules or atoms present in gases, fluids, and other
solids creates energy and it may be in the form of heat.
Answer:So, one mole of water has a mass of 16 +1+1 = 18 grams. So, if one mole has a mass of 18 grams, 25 grams would have a mass of 25 grams/ 18 grams per mole or 1.39 moles
Given question is incomplete. The complete question is as follows.
Balance the following equation:
Answer: The balanced chemical equation is as follows.
Explanation:
When a chemical equation contains same number of atoms on both reactant and product side then this equation is known as balanced equation.
For example,
Number of atoms on reactant side:
H = 5
P = 1
O = 6
Ca = 1
Number of atoms on product side:
H = 6
P = 2
O = 9
Ca = 1
In order to balance this equation, we will multiply 
by 2 on reactant side and we will multiply 
by 2 on product side. Hence, the balanced chemical equation is as follows.
