Answer:
A average is a number expressing the central or typical value in a set of data. add up all the numbers, then divide by how many numbers there are.
Explanation:
Answer: The products are sodium acetate 
and solid silver chloride 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The reaction of aqueous solutions of sodium chloride and silver (I) acetate is :
Thus the products are aqueous sodium acetate and solid silver chloride
Well the average American makes about 29 pounds a week so, 52x29= 1508. the average American generates about 1508 pounds a year.
To solve this question, we first need to know the mass of one mole of mercury. This can be done by checking the periodic table.
From the periodic table, we can see that:
molar mass of mercury = 200.59 grams/mole.
From the measurements, the chemist found that the participated amount of mercury is 0.02 moles.
We can simply determine the mass of 0.02 moles by doing cross multiplication as follows:
mass of 0.02 moles = (0.02 x 200.59) / 1 = 4.0118 grams
Rounding the answer to 2 significant digits, we get:
mass of 0.02 moles = 4.01 grams
Answer: Calcite is softer than fluorite.
