<h3>
Answer:</h3>
1 Nitrogen atom and 3 Hydrogen atoms
<h3>
Explanation:</h3>
- A molecule is the smallest particle of an element or a compound that has the properties of the element or the compound.
- Molecules of elements are made up of similar atoms while those of compounds are made up of different atoms from different elements.
- Compounds are made up of atoms of different elements.
- For example, NH₃ is made up of one nitrogen atom and three ammonia atoms, water(H₂O) is made up of two hydrogen atoms and one oxygen atom.
A flask with a volume of 125.0 mL contains air with a density of 1.298 g/L. what is the mass of the air contained in the flask<span>The given are: </span>
<span><span>1. </span>Mass = ?</span><span><span /></span>
<span><span>2. </span>Density = 1298 g/L</span>
3. Volume = 125mL to L
a. 125 ml x 0.001l/1ml = 0.125 L
<span>Formula and derivation: </span><span><span>
1. </span>density = mass / volume</span> <span><span>
2. mass </span>= density / volume</span>

Explanation:
Chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction.
Purple stem plants can be formed by genetics, they use their energy slightly different from other plants, they use less energy, but that may also be because of bad nutrition, and because they may be hungry for nutrients.
