Consider three gases: Ar, SF6, and Cl2. If 50.0 grams of these gases are placed in each of three identical containers, which container will have the highest pressure? The volume and temperature of all three containers are the same.
Answers
p - pressure, n - number of moles, R - the gas constant, T - temperature, V - volume
The volume and temperature of all three containers are the same, so the pressure depends on the number of moles. The greater the number of moles, the higher the pressure.
The mass of gases is 50 g.
The greatest number of moles is in the container with Ar, so there is the highest pressure.

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.

when the pressure is low and the temperature is low

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.
What is periodic table?
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:
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.

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.
