Answer:
If a compound is made of a cation and an anion it is a salt by definition in chemistry.
The simplest salts are compounds of one kind of metal cation with one kind of non-metal anion. If you look at a periodic chart, there's a dark, stair-step line over on the right. The atoms to the left of it are metals and those to the right are non-metals and some of those on the steps (not aluminum) are semi-metals or metalloids.
Then, you were given, or can look up online, a list of polyatomic ions. Memorize these.
Compounds with a metal cation and a polyatomic anion are also salts. Compounds with a polyatomic cation and any anion, are also salts.

Answer:
75 g of water
Explanation:
Thermal energy refers to <em>an object's internal energy.</em> This internal energy is brought about by<em> kinetic energy</em> <em>(energy due to motion).</em> If two objects have the same mass, their thermal energy can be drawn upon the presence of varying temperatures. However, in the case above, both water and metal pot have the same mass and temperatures. Thus, we have to compare both of them in terms of "specific heat" (not on the basis of temperature).
Specific heat is <u>a form of thermal energy.</u> It refers to the object's resistance when there is a change in temperature. Water is said to have more specific heat than metals. In fact, is has a "high specific heat." This means that once the water is heated, it takes a longer time for it to cool down compared to metals. This is because<em> its heat loss is in a slower process. </em>
Thus, a 75 g of water has more thermal energy than a 75 g of metal pot.
Amonium= NH4+
Sulphate= SO4-2
Together they form: (NH4)2SO4
the molar mass is: <span>132.14 g/mol</span>
They are all rocks and they are all solid
