Answer:
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using SI derived unit, the cubic meter.
Explanation:
Answer:
0.536 mol HNO₃
Explanation:
Step 1: Convert 37.0 g of NO₂ into mol NO₂:
37.0 g NO₂ x 1 mol NO₂/46.0 g NO₂ = 0.8043 mol NO₂
Step 2: Convert 0.8043 mol NO₂ into mol HNO₃:
0.8043 mol NO₂ x 2 mol HNO₃/3 mol NO₂ = 0.5362 mol HNO₃
Step 3: Round to 3 significant figures:
0.5362 mol HNO₃ -> 0.536 mol HNO₃
Finding neutrons = Mass number - proton number.
For finding neutrons for phosphorus = 31-15
=16.
There are three kinds of Hydrogen in 2-methyl-2-butene
The correct question is
How many kinds of hydrogen atoms are present in 2-methyl-2-butene
<h3>What is an atom ?</h3>
Atom was discovered by Dalton's Atomic theory , he predicted that each element consist of large number of a very small thing known as atom.
In the structure of 2-methyl-2-butene there are 3 types oh Hydrogen
1. Attached to the Carbon atom connecting the methyl ion to the butene
2. Connected to the last Carbon atom
3. Connected to the Carbon bond having double bond.
Therefore there are three kinds of Hydrogen in 2-methyl-2-butene.

In Alpha decay two neutrons and protons are lost, so the mass decreases by four and the atomic number decreases by two.
Therefore the correct answer is B: Ra-224.
