Group 16 elements, also known as chalcogens, commonly react with nonmetals to form compounds.
In chemistry, group 16 elements are known as the chalcogens. Chalcogens react with various groups of elements, including metals and nonmetals. However, their reactions with nonmetals are more common.For example, sulfur (group 16) readily reacts with most nonmetals to form compounds. The resulting compounds can vary depending on the specific nonmetal involved. Therefore, the group that would most likely react with group 16 to form a compound is the nonmetals group.

The total number of atoms in 1.3 x 10^22 molecules of N(O)2 is 3.9 x 10^22 atoms since each molecule of N(O)2 consists of three atoms.
To answer the question of how many atoms there are in 1.3 x 10^22 molecules of N(O)2, one must be aware of the molecular composition of N(O)2. This molecule contains one nitrogen atom and two oxygen atoms, thus comprising three atoms in total. Consequently, to determine the total number of atoms, multiply the number of molecules by the number of atoms per molecule. Hence, the answer is 1.3 x 10^22 molecules * 3 atoms/molecule = 3.9 x 10^22 atoms.

Energy released from changing the phase of a substance from the gas phase to liquid phase can be calculated by using the specific latent heat of vaporization. The heat of fusion of water at 0 degrees Celsius is 40.7 kJ/mol. Calculation are as follows:
Energy = 27.9 g (1 mol / 18.02 g) x 40.7 kJ/mol
Energy = 63.09 kJ
Answer:
C- 63.09 kJ
Explanation:
I have several degrees
b. Energy flows from the surroundings to the ice.
c. Water molecules lose energy.
d. The temperature of the ice increases as it melts
