I'm not sure how many sign fig's you are required to have.
However I think the final answer would be 0.05 Moles, because of the .5g, that is considered 1 sign fig.
The answer is 300
3 * 100
3 * 10 * 10
30 * 10
300

True, cracking distillation is one process used to break hydrocarbons into smaller and more useful parts. This is achieved by using high temperatures and pressures with a catalyst. The most common catalyst used are the zeolites.
electron dot structure
Explanation:
Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.
- The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
- The chemical symbol represents the nucleus and all electrons except the valence ones.
- The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
- Chlorine has 7 valence electrons in its outermost shell.
- It is made up of 3 lone pairs and 1 odd pair of electron.
- The odd pair accounts for the reason why chlorine is very reactive.
- It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.

Answer:
B) Because you are adding positively charged protons, which pull in the outer electrons.
Explanation:
Since the increase in protons have a greater effect then the increase in electrons the protons pull the electrons in closer resulting the radius of an atom to decrease from left to right across a period.
