Ionic compound
Plasma contains a small proportion of free electrons, which are not bound to any atoms and instead flow freely in the plasma.
Heat is caused by the vibration within atoms. Space is a vacuum and therefore there are no atoms to have any heat.
Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
Yes
A half.
Any two ratios, provided the second is not 0, form a proportion.
Probably. But they will want a proportion, perhaps a big proportion.
Take any two of them and divide. 14/27 is a proportion
The same as any other atoms.
The formula for the formula unit of anhydrous iron (III) acetate is Fe(C2H6O2)3. Tally the atoms as follows: Multiply the subscript within parentheses by the subscript after the parentheses to obtain 6 carbon atoms, 18 hydrogen atoms, and six oxygen atoms; add the one atom of iron (implied by lack of any subscript immediately following it); the total is 31 atoms.
