Answer:
The correct answer is Option
B. A homogeneous mixture
Explanation: Mixture is solution which is made of two or more than two substances which are combined only physically not chemically. There are two types of mixture i. e. Homogeneous mixture and heterogeneous mixture. Homogeneous mixture is a mixture in which the substances which are combined are uniform in appearance and heterogeneous mixture is a mixture in which substances are suspended in the solution and easily differentiated.
Answer:
<h2>9.93 × 10²³ atoms</h2>
Explanation:
The number of atoms of potassium can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 1.65 × 6.02 × 10²³
We have the final answer as
<h3>9.93 × 10²³ atoms</h3>
Hope this helps you
Answer:
Can either be a solid, a liquid or a gas
Explanation:
A solvent can either be a solid, liquid or a gas. It is the carrier medium in a solution. It is the one in which the solute is dissolved.
Although quite unusual, a solvent might also be a solid. An important application of this can be seen in the production of alloys. Alloys are mixture of metals. To produce let’s say an alloy containing just two metals, the use of a solid solvent is needed. Here, one of the two metals is known as the base metal. It is this base metal that will serve as the carrier medium for the other metal
The answer is true, particles in the gaseous state are the furthest apart
