Answer:
a.monadioxide
Explanation:
for maintaince of different gases in the air to separate reactions of chemicals
Answer:
It is winter in the Southern Hemisphere.
Explanation:
At point c, we see the southern hemisphere is tilted away from the sun. This means that it is winter. We can also verify our answer by noticing that the northern hemisphere is tilted towards the sun.
Idk if this is the information you need but the energy level gets higher the farther you move down the Periodic Table. Every element in a vertical line has the same energy level.
The boiling point and melting point of substances is determined by their molecular weight and the cohesion (stickiness) of the individual molecules in the substance.
Based on the cohesive molecule - molecule interactions of a substance, it may have either a high melting and boiling point or vice versa. The stronger the cohesive interactions the more the heat required for the substance's transition into liquid and gas state.
These intermolecular forces include hydrogen bonding , ionic bonding, dipole dipole, and Van Der Waals dispersion forces.
