Gases best dissolve in liquid under low temperature. This is because when you increase the temperature it will cause an increase in kinetic energy. An increase in kinetic energy means there would be an increase in molecular motion of gas particles. This would cause for gas particles to escape to the gas phase thus making it difficult for it to be dissolved.
Answer:
when the pressure is low and the temperature is low
Explanation:
In the periodic table, the group number of astatine is 17 while that of tellurium is 16, hence the size of astatine is larger as compared to tellurium as it has one more shell present in it's atom.
Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.
It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.
Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.

Answer:
monomer
Explanation:
a single unit of a organic molecule is called a monomer
Answer:
Copper (I) carbonate or cuprous carbonate.
Explanation:
Hello,
In this case, by considering the given formula, we identify the copper's oxidation state as +1 since the carbonate anion is -2 and copper's subscript is 2, therefore +1 is its oxidation state. On the other hand, carbon's oxidation state in CO₃⁻² is +4, that is why according to the IUPAC rules, its name is carbonate. Thus, one sums up that the chemical name of the given compound is copper (I) carbonate or cuprous carbonate.
Best regards.
IF SOMEONE COULD JUST HELP ME OR EXPLAIN HOW TO DO IT PLEASE! THANK YOU

Explanation:
not sure if this is totally correct but checked with classmates and this seems to be around what most got
Answer:
It's funny cause i'm doing the same exact thing as you.
Explanation:
You need to go to the Gizmo, and it explains everything. But When you're looking at "Valence Electrons" thats how many "dots" (electrons) there are on the outermost circle, so Fluorine has 7 Valence Electrons. To find the valency, you need to first identify the Valence Electrons. Fluorine has 7 valence electrons, and it would be a lot easier for this atom to gain an electron, rather than lose 7. So 8-7 is 1, meaning the Valency of Fluorine will be 1. For the sum, just add the total number, so 7+1 is 8, so the sum of Fluorine will be 8. This is confusing, so I'm sorry if this doesn't make sense.
