The Kinetic Molecular Theory has 5 main tenets, and they basically explain that the gas molecules are in constant motion. It is random and it causes constant collisions between the particles and also with the container's walls.
So, the answer is B. Kinetic Molecular Theory.
Answer:
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon. In the periodic table of the elements, it is expected to be an s-block element, an alkali metal, and the first element in the eighth period. It is the lightest element that has not yet been synthesized.

Answer:
3.918 mol Al
Explanation:
To convert between moles and grams, you have to use the molar mass of the substance. The molar mass of aluminum is 26.98 g/mol. You use this as the unit converter.
Round the number to the lowest number of significant figures; 3.918 mol Al
The formula can be empirical because the subscripts are reduced to the lowest fraction.
To check if this formula is also the molecular formula we can check by obtaining the molar mass of the compound it is equal to the given molar mass. Thus
12*2 + 4*1 + 16 = 44 g/mol
this is ~equal to the given molar mass thus the given equation can be both empirical and molecular.
Calcium carbonate + sulfuric acid -> calcium sulfate + carbon dioxide + water
3 + 24→4+ 2+2
