The GPS or global positioning system is a satellite – based navigation system made up of a network of 24 satellites placed into orbit by the US Department of Defense. It was originally intended for military applications but later one, it made available for civilian use. It works in any weather conditions, anywhere in the world for 24 hours a day.
A change on the molecular level.
A change in appearance.
A change in taste.
A change in form.
The phrase that most accurately describes a chemical change is; "A change on the molecular level."
The major difference between a physical change and a chemical change is that a chemical change involves a change in the composition of a substance.
This implies that the atoms in a substance are rearranged during a chemical change.
This rearrangement of atoms corresponds to change on a molecular level.

True
False
Correct Answer: TRUE
The other answer is incorrect, I just did the assignment and got it right.
If water is added to 100 ml of a 0.15 M NaOH solution until the final volume of 150 ml. The molarity of the diluted solution is 0.1 mol. L.
Molarity is the measure of the concentration of any solute per unit volume of the solution.
Moles of solute is
Volume is 150 ml
Putting the value
Thus, the molarity of the diluted solution is 0.1 mol. L.

Answer is: another name for groups of elements is family.
There are 18 numbered groups in the periodic table.
The elements in a group have similar physical or chemical characteristics and some groups have a specific name, for example group 17 (the halogens).
Elements in the group have the same number of valence electrons, for example, chemical elements in group 15 of the periodic table have neutral atom with a valence electron configuration of ns²np³.
In Chemistry, groups of elements are often referred to as families or groups.
In Chemistry, groups of elements are often referred to as families or groups. These groups are organized based on similar properties and characteristics. For example, the alkali metals (group 1) and the halogens (group 17) are two well-known families of elements.
