Why are chemical reactions often carried out using solutions? The heterogenous nature of solutions prevents the reactants from f

reely mixing. The amount of each reactant can be controlled by adjusting the volume of each solution that is used. Even very small amounts of reactants can be combined by using dilute solutions. A color change will always occur when a reaction is conducted in solution. The molecules or ions in a solution can freely intermingle. The solvent must always be water, so it is impossible for a fire to start.

Answer:

The molecules or ions in a solution can freely intermingle.  

Explanation:

The reactant molecules and ions can move freely in solution, so thy are more likely to collide with each other and form products.

A is wrong. Solutions are homogeneous.

B and C are wrong. The statements are correct, but they are not the reason why reactions are carried out in solution.

D is wrong. Chemical reactions do not always produce a colour change.

F is wrong. Some chemicals react with water, so other (often flammable) solvents must be used.

How many moles of FeCl3 could be produced from 6.1 moles of Cly?<br> 2 Fe + 3Cl2 —&gt; 2 FeCl2
Black_prince [1.1K]

Answer:

4.1 moles of FeCl₃

Explanation:

The reaction expression is given as shown below:

         2Fe    +       3Cl₂   →    2FeCl₃

Number of moles of Cl₂  = 6.1moles

So;

  We know that from the balanced reaction expression:

                       3 moles of Cl₂ will produce 2 moles of FeCl₃

Therefore    6.1moles of Cl₂ will produce \frac{6.1 x 2}{3}   = 4.1 moles of FeCl₃

The number of moles is 4.1 moles of FeCl₃

A solution of H 2 SO 4 ( aq ) H2SO4(aq) with a molal concentration of 8.01 m 8.01 m has a density of 1.354 g / mL . 1.354 g/mL.
anzhelika [568]

Answer:

[H₂SO₄] = 6.07 M

Explanation:

Analyse the data given

8.01 m → 8.01 moles of solute in 1kg of solvent.

1.354 g/mL → Solution density

We convert the moles of solute to mass → 8.01 mol . 98g /1mol = 785.4 g

Mass of solvent = 1kg = 1000 g

Mass of solution = 1000g + 785.4 g = 1785.4 g

We apply density to determine the volume of solution

Density = Mass / volume → Volume = mass / density

1785.4 g / 1.354 g/mL = 1318.6 mL

We need this volume in L, in order to reach molarity:

1318.6 mL . 1L / 1000mL = 1.3186 L ≅ 1.32L

Molarity (mol/L) → 8.01 mol / 1.32L = 6.07M
