Chemistry
1 answer:
Leya [2.2K]3 years ago
3 0

Answer:

54g

Explanation:

Given parameters:

Number of moles of H₂O  = 3 moles

Unknown:

mass of water  = ?

Solution:

To solve this problem, we use the expression below:

         mass  = number of moles x molar mass

Molar mass of H₂O  = 2(1)  + 16  = 18g/mol

Mass of water  = 3 x 18  = 54g

Predict the precipitate that will be formed in the following reaction:<br> NaF(aq) + AgNO3(aq) →
netineya [11]

The precipitate that will be formed : AgF

<h3>Further explanation</h3>

One indication of the double displacement reaction is the precipitation reaction

Solubility Rules:  

• 1. soluble compound  

All compounds of Li +, Na +, K +, Rb +, Cs +, and NH4 +  

All compounds of NO₃⁻ and C₂H₃O₂⁻  

Compounds of Cl−, Br−, I− except Ag⁺, Hg₂²⁺, Pb²⁺  

Compounds of SO₄²⁻ except for Hg₂²⁺, Pb²⁺, Sr²⁺, Ba²⁺  

• 2. insoluble compounds  

Compounds of CO₃²⁻ and PO₄³⁻ except for Compounds of Li +, Na +, K +, Rb +, Cs +, and NH₄ +  

Compounds of OH− except Compounds of Li +, Na +, K +, Rb +, Cs +, NH₄⁺, Sr²⁺, and Ba²⁺  

Reaction

NaF(aq) + AgNO₃(aq) →NaNO₃(aq)+ AgF(s)

From the solubility rules above, it has been shown that the salts of the Ag⁺ cations are insoluble salts

What will happen to a blood cell that is placed in a solution with a greater concentration of solutes?
larisa [96]
<span>Eventually the increase in water may cause the blood cells to burst (cytolysis.) In a hypertonic solution, the concentration of dissolved solutes is greater than that of the cell. ... If the salt solution outside is 20% salt, then the water concentration is 80%. The red blood cells will shrink in size due to osmotic-like pressure differences until it reaches a "favorable" size.</span>

using the scientific definition of work, does moving an object a greater amount of distance always result in more work?
DochEvi [55]
No. i can go from my house to New York and back in a day since my final destination is the same as my beginning no work is done. if i go 20 ft from the house and stay i would have done more work. displacement is the key

What is the volume of an 2.3 m solution with 212 grams of calcium chloride (cacl2) dissolved in it?
ira [324]

830 mL

The volume of an 2.3 m solution with 212 grams of calcium chloride (cacl2) dissolved is 830 mL.

The solution has a concentration of 2.3 mol/L.

<h3>a) Moles of CaCl2</h3>

Molar mass of CaCl2 = 110.98 g/mol

Moles of CaCl2 = 212 g CaCl2 x (1 mol CaCl2/110.98 g CaCl2)

= 1.910 mol CaCl2

<h3>b) Volume of solution</h3>

V = 1.910 mol CaCl2 x (1 L solution/2.3 mol CaCl2) = 0.83 L solution

= 830 mL solution

<h3>How much CaCl2 is there in the solution by molarity?</h3>
  • The number of moles is 0.125 x 2 = 0.25 mol since the molarity is 2.0M.
  • To get the answer of 27.745 g, simply multiply this by the molar mass of calcium chloride, which is 110.98 g/mol.
