The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.
<h3>What is Molecular Formula ?</h3>
The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.
<h3>What is Atomic Number ?</h3>
The number of proton which is used to separate one element from the other element is called Atomic Number.
here the atomic of the element Q is 90 and the atomic number of R is 53. The element Q is Thorium. Symbol of Thorium is Th. The element R is Iodine. Symbol of Iodine is I.
The valency of thorium is +4 and valency of Iodine is -1. So the formula of the compound is ThI₄.
Thus from the above conclusion we can say that The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.

The rule of three is a way to solve problems of proportionality between three known values and one unknown. <u>This is an operation of finding the fourth term of a proportion knowing the other three</u>.
We can use the rule of three to solve this problem in this way,
500 mL → 6 grams
40 mL → x
This is the same as saying: if in 500 mL there should be 6 grams of agarose powder then in 40 mL how many grams should there be?
So,
→ x = 0.48 g = 480 mg
Then, you need to dissolved 480 mg of agarose powder in 40 mL of water to meet the recipe.
Answer:
they're different because one is carbon and the other is cabohydride
Explanation:
CH is a mix between carbon and hydrogen C is carbon
