Final answer:
Group 16 elements, also known as chalcogens, commonly react with nonmetals to form compounds.
Explanation:
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 answer is (a.) more solid
Adding hydrogen atoms to an unsaturated fatty acid will make it more solid. This process is called hydrogenation. In this process, hydrogen is added to an unsaturated fatty acid to make it more saturated and thereby more solid at a room temperature.

Answer: The alkane containing 100 hydrogens will be
Explanation:
Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms.These are called as alkanes. The general formula for these hydrocarbons is
As given number of hydrogen atoms is 100, therefore the value of (2n+2) = 100
2n = 98
n = 49
Thus the formula for the alkane containing 100 hydrogens will be
Final answer:
The alkane containing 100 hydrogens has the formula C49H100.
Explanation:
The formula for the alkane containing 100 hydrogens can be determined using the general formula for alkanes, which is CnH2n+2. To find the value of n, we can set up an equation:
100 = 2n + 2
Simplifying this equation, we get:
n = 49
Therefore, the formula for the alkane containing 100 hydrogens is C49H100.

For chemical changes like precipitation, appropriate use of a beaker is to provide space for the precipitate to form and for the color of the precipitate to be distinct.
Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
Thus, appropriate use of a beaker is to provide space for the precipitate to form and for the color of the precipitate to be distinct.
