Answer:

- is reused and recycled

- can dissolve more substances than any other liquid

Explanation:

Earth water is reused and recycles in the form of the water cycle (hydrological cycle). In this cycle, water from the earth surface evaporates in the atmosphere, cool and condense into cloud or snow and fall to the earth surface.

As a universal solvent, water can dissolve more substances than any other liquid. The polar arrangement of oxygen and hydrogen atom in the water molecules makes it excellent salt.

On Earth, ~2.5% is a freshwater whereas 97.5% is salt water. The pH of water differs for surface and salt water, i.e. neutral to alkaline respectively. Water molecules attract to other water molecules better than the other substances. Therefore, other options are incorrect.

What is the empirical formula for a substance that contains 3.730% hydrogen, 44.44% carbon, and 51.83% nitrogen by mass?\?
Vlada [557]

Given data:

Hydrogen (H) = 3.730 % by mass

Carbon (C) = 44.44%

Nitrogen (N) = 51.83 %

This means that if  the sample weighs 100 g then:

Mass of H = 3.730 g

Mass of C = 44.44 g

Mass of N = 51.83 g

Now, calculate the # moles of each element:

# moles of H = 3.730 g/ 1 g.mole-1 = 3.730 moles

# moles of C = 44.44/12 = 3.703 moles

# moles of N = 51.83/14 = 3.702 moles

Divide by the lowest # moles:

H = 3.730/3.702  = 1

C = 3.703/3.702 = 1

N = 3.702/3.702 = 1

Empirical Formula = HCN
