Explanation:it is a homogeneous mixture
D. A salt e.g NaCl is held by ionic bond
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.
C. The neutron number.
An element is determined based on how many protons has, if the protons number change then you got a new element.
If the number of neuron change you got the same element except it will be a bit heavier or lighter if you are gaining or loosing neutrons. Those variations of an element are called the isotops of the element.
The protons and neutrons toghether form the nucleus of the atom that is heavy and dense as an elephant.
The electrons are light as fleas and stay on the shels of around the nucleus and if they are more then the number of protons they make the atom negatively charged and vice versa.
