Answer:

D

Explanation:

It was later identified that atoms of the same element can be different. This is mostly seen in elements with different isotopes. An example is carbon-14 and carbon-12 that have different masses due to differences in neutrons numbers in their nuclei.

Atoms are also divisible into subatomic particles. Today, atoms can be smashed apart into neutrons, protons and electrons particles. This also occurs naturally in radioactive decay.

What is an aqueous solution? What is an aqueous solution? An aqueous solution is a homogeneous mixture of a substance with water
mestny [16]

Answer:

The answer to your question is: first option.

Explanation:

What is an aqueous solution?

Aqueous solution is a solution which solvent is water and is homogeneous.

a) An aqueous solution is a homogeneous mixture of a substance with water.  This is the correct definition of aqueous solution because it mentions the characteristics of this kind of solutions.

b) An aqueous solution is a dispersoid solution. This option is wrong, it is a homogeneous solution, and the description do not mention water.

c) An aqueous solution is a mixture of a liquid substances. Aqueous solution is a mixture but one of the components is water not a liquid substance.

d) An aqueous solution is a heterogeneous mixture of a substance with water. Aqueous solution is homogeneous not heterogeneous, this option is wrong.

On which part of the carbon cycle have humans had the greatest impact? storage of co2 in the oceans all of the answer options ha
yarga [219]
Hello!

The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.

The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.

Have a nice day!
