Answer:
the answer would be the first one, gamma decay
Answer:
A. The kinetic molecular theory relates the properties of a state of matter to the motion of its molecules.
Explanation:
The higher the kinetic energy of the molecules, the faster its movement will be. The state of a matter will depend on how fast the molecules move. When the molecules barely move, it will be packed tightly and its state will be solid. If the molecules kinetic energy rises, eventually they start moving around and the state will be liquid. If the kinetic energy rises further, the molecule will expand and changed into gas form.
Answer:
Six
Explanation:
Mᵣ = 46
Aᵣ(C) = 0.522 × 46 = <u>24</u>
Difference = 22
Less 1 O = <u>-16
</u>
Aᵣ(H) = 6
The relative atomic mass of the H atoms is 6.
The molecule contains six hydrogen atoms.
The answer is 4.0 moles of magnesium
because...
..
...4.0mol Makmol O2 =3.0mol O2
Answer:
Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).
