Explanation:

Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Calculate the mass of grams of 14.79ml of a substance. It'd density is 1.193gml

Alisiya [41]

<span>D=m/v

Given:
d=1.193g/ml
v= 14.79ml

Solution
m=dv
m=1.193g/ml x 14.79ml

m= 17.644g

Density is the mass per volume of the material. Basically, it refers to the measurement of how crammed together is the matter. The formula to calculate density is rho = m/v wherein rho is the density, m stands for the mass and v stands for the volume.</span>

A certain material has a normal freezing point of 10ºC and a normal boiling point of 70ºC. What state is the material in at room

ahrayia [7]

Explanation:

A freezing point is defined as the point in which a liquid state of a substance changes into solid state.

Whereas boiling point is defined as the point at which liquid state of substance starts to convert into vapor state.

So, a substance is freezing at $10^{o}C$ and boils at $70^{o}C$ then it means at room temperature, that is, around $25^{o}C$ the substance is present in liquid state.
