As what we see in the chemical reaction that is given, we can conclude that the Lithium must be the reducing agent since it is the one that is oxidised. In addition to that, a redox reaction or simply known as the oxidation-reduction reaction usually operates when electrons get transferred between species.
Answer:
d = 0.53 g/mL
Explanation:
Given that,
Mass of an unknown metal = 40 g
The volume of the metal = 75 mL
We need to find the density of the metal. We know that,
Density = mass/ volume
So, the density of the metal is 0.53 g/mL.
There are certain processes in nature that produce many of these radioactive<span>isotopes. For instance, some </span>radioactive<span> nitrogen is produced in the atmosphere when high energy cosmic radiation from the sun hits the earth. Other </span>radioactive<span>isotopes are only available by artificial production. good luck</span>
A. Side B has higher concentration of particles than side A
Answer: Option (b) is the correct answer.
Explanation:
In solids, atoms are held together because of strong intermolecular forces of attraction between them.
As a result, solids have a definite shape and volume. Hence, its molecules are not able to slide past each other.
Whereas in liquids, molecules are together by less strong forces as compared to solids. Therefore, liquids do not have fixed shape and volume. They occupy the shape of a container in which they are kept together.
Therefore, molecules of a liquid are able to slide past each other.
In gases, molecules are held by weak Vander waal forces. So, they collide rapidly and occupy the volume of container and not the shape. Similarly, plasma is a hot ionized gas which consists of positive ions and negative electrons. Like gases, plasma also occupies the volume of a container.
Thus, we can conclude that liquid is the matter which can fill a container from top to bottom.
