They are not chemicall combined, in order for something to be an element it has to be chemically combined. salsa and trail mix are mixtures, also mixtures can be easily picked apart, like you can seperate the pretzels and the m&ms
Answer:
The heat of vaporization of the gold sample is 1577.397 joules per gram.
Explanation:
The latent heat of vaporization of gold (), in kilojoules per gram, is the heat required by a unit mass of gold to transform the material from liquid to gas:
(1)
Where:
- Energy required for vaporization, in joules.
- Mass, in grams.
If we know that and , then the heat of vaporization of the gold sample is:
The heat of vaporization of the gold sample is 1577.397 joules per gram.
0.1m moles of solute particles are present in 1 L of each of the following aqueous solutions.
The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol
<h3>What is meant by moles of solute?</h3>
Molality is defined as moles of solute per kilogram of solvent. Molality = mass of solvent (in kg) moles of solute = molecular weight of solute × mass of solvent (in kg) mass of solute.

Answer:
Explanation:
2Ca is the elemental form of calcium. There are 2 mols of calcium in whatever equation you are talking about.
Ca_2 means that there are 2 ions of Calcium making up something like
Ca3(PO4)2 means that you have the compound Ca3(PO4)2 with 2 mols of PO4 and 3 moles of Ca
It is hard to come up with something composed of Ca2 because unless the other ion is odd, the 2 will divide into something.
