Solutions of sodium sulfate and silver nitrate are mixed together.
Vera_Pavlovna [14]

Answer:

<em>The correct option is a) Precipitate: silver sulfate </em>

<em> </em>

<em>Net Ionic: 2Ag+ +  SO42 →Ag2SO4</em>

Explanation:

When sodium sulfate reacts with silver nitrate, the following reaction occurs:

2AgNO3 + Na2SO4  → Ag2SO4 + 2NaNO3

The NaNO3 is easily soluble in water. However, silver ions form an insoluble solid with SO4. The Ag+ in this compound will be a cation having a positive charge. The SO4- will be an anion having an negative charge.

The table with solubility rules show that the sulfates of  Ag+, Ca+, Sr2+, Ba2+, Hg22+ and Pb2+ are insoluble.

How many miles of iron can be produced from 3.5 moles of Fe2O3 and 6.2 moles of CO
AlekseyPX

Answer:

4.13 moles of Fe.

Explanation:

Given data:

Moles of iron produced = ?

Moles of Fe₂O₃ = 3.5 mol

Moles of CO = 6.2 mol

Solution:

Chemical equation:

Fe₂O₃ +  3CO      →    2Fe + 3CO₂

Now we will compare the moles of iron with CO and Fe₂O₃.

                 Fe₂O₃        :         Fe

                      1             :          2

                  3.5             :         2/1×3.5 = 7 mol

                 CO              :          Fe

                   3               :            2

                 6.2              :        2/3×6.2 = 4.13 mol

The number of moles of iron produced by CO are less it will limiting reactant.

Thus, moles of iron formed in given reaction are 4.13 moles.

Determine the freezing point of a water solution of fructose (C6H12O6) made by dissolving 92.0 g of fructose in 202 g of water.
Naya [18.7K]

Answer:

THE FREEZING POINT OF A WATER SOLUTION OF FRUCTOSE MADE BY DISSOLVING 92 g OF FRUCTOSE IN 202g OF WATER IS -4.70 ◦C

Explanation:

To calculate the freezing point of a water solution of fructose,

1. calculate the molar mass of Fructose

( 12 * 6 + 1*12 + 16*6) =72 + 12 +96 = 180 g/mol

2. calculate the number of moles of fructose in the solution

number of moles = mass / molar mass

n = 92 g / 180 g/mol

n = 0.511 moles.

3. calculate the molarity of the solution

molarity = moles / mass of water in kg

molarity = 0.5111 / 202 g /1000 g

molarity = 0.5111 / 0.202

molarity = 2.529 M

4. calculate the change in the freezing point of pure solvent and solution ΔTf

ΔTf = Kf * molarity of the solute

Kf = 1.86 ◦C/m for water

ΔTf = 1.86 * 2.529

ΔTf = 4.70 C

5. the freezing point is therefore

0.00 ◦C - 4.70 ◦C = -4.70 ◦C
