B, because gamma rays are the only atomic emissions (out of alpha, beta and gamma).
Answer is: <span>edge of the length of the box measured is 1280,57 kilometers.
</span>V(raindrop) = 3,48 cm³.
V(cubic box) = 3,48 cm³ · 6,023·10²³.
V(cubic box) = 2,1·10²⁴ cm³.
V(cubic box) = 2,1·10²⁴ cm³ ÷ 10¹⁵.
V(cubic box) = 2,1·10⁹ km³.
r(cubic box) = ∛2,1·10⁹ km³.
r(cubic box) = 1280,57 km.
Mixtures are of 2 types.
1) Homogeneous mixture : In this type of mixture, the components of the mixture are present in the same phase. For example, Air. Air is a mixture of different gases which cannot be distinguished from each other.
2) Heterogeneous mixture : In this type pf mixture, 2 or more phases can be seen. The composition of the different components is not the same throughout the mixture.
Ex. mixture of oil and water. Here we can see 2 different phases one consisting of oil layer and the other made of water layer.
Salt water is a mixture of salt and water. Since salt is completely soluble in water, it creates a homogeneous mixture when mixed with water. We cannot distinguish salt and water once they are mixed.
To get fresh water from the salt water in the ocean, we can set up a simple distillation unit . In this, the salt water is heated to its boiling point and the vapors thus formed are allowed to cool which condense and create liquid water. This can be used as fresh water.
The oxidation number of V and Al in each ion is +3 and +4 respectively.
<h3>What is oxidation number in chemistry?</h3>
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
<h3 /><h3>Why is it called oxidation number?</h3>
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.
