Answer:
a) Mass of solution is 16,605 milli grams.
b) 57.29 grams is the mass of calcium chloride in 431.3 mL of a 12.0 wt% solution.
c) 1.1967 mol/L is the formal concentration of calcium chloride in 431.3 mL solution.
Explanation:
Mass by mass percentage of calcium chloride solution, wt% = 12.0%
Density of the solution = d = 1.107 g/mL
a) Volume of the solution , V= 15.0 mL
Mass of the solution = m
Mass of solution = 16.605 g = 16,605 mg (1g = 1000 mg)
b) Mass of the solution = m
Volume of the solution = V = 431.3 mL
Mass of calcium chloride = x
w% = 12.0%
57.29 grams is the mass of calcium chloride in 431.3 mL of a 12.0 wt% solution.
c) Moles of calcium chloride = 
V = Volume of the solution in Liters
n = 0.5161 mole
V = 431.3 mL = 0.4313 L
1.1967 mol/L is the formal concentration of calcium chloride in 431.3 mL solution.
It's one ratio per substance so say if you had N2 + 3H2 > 2NH3 (chemical equation for the synthesis of ammonia) just look at the number coefficients(for 3H2 the coefficient would be 3 and for 2NH3 the coefficient would be 2 and so on)So it would take 1mole of nitrogen to react with 3 moles of hydrogen In order to produce 2 moles of ammonia so there would be 6 ratios you could write comparing two substances at a time In a reaction involving 3 substances ^^; hope this helps somewhat ^^;
The movement of liquids and gases is generally referred to as a flow,” A concept that describes how fluids behave and how they interact with their surrounding environment .
<u>Answer:</u> The net ionic equation contains 
ions
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of ammonium sulfate and calcium nitrate is given as:
Ionic form of the above equation follows:
As, ammonia and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation contains ions
