Answer:

a concentrated solution is one that has a relatively large amount of dissolved solute. a dilute solution is one that has a relatively small amount of dissolved solute.however, these terms are relative, and we need to be able to express concentration in a more exact, quantitative.

The total amount of energy before and after a chemical reaction is the same. Therefore, energy is _____.
BabaBlast [244]

Answer:

Option (a) is the correct answer.

Explanation:

The law of conservation of energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Therefore, the total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.

Therefore, we can conclude that option (a) is the correct answer.

17) Chlorine and Fluorine react to form gaseous chlorine trifluoride. You start with 1.75 mole of chlorine and 3.68 moles of flu
Mama L [17]

Answer:

a) Cl_2 + 3F_2 \rightarrow 2ClF_3

b) F_2 is the limiting reagent

c) Moles of ClF_3 produced = 2.45 mol

b) Moles of Cl_2 left = 1.75 -1.22 = 0.53

Explanation:

a) Balanced reaction:

Cl_2 + 3F_2 \rightarrow 2ClF_3

b)

No. of mole of Cl_2 = 1.75\ mol

No. of mole of F_2 = 3.68\ mol

Cl_2 + 3F_2 \rightarrow 2ClF_3

As, it is clear from the reaction that,

1 mol of Cl_2 requires 3 moles of F_2

1.75 mol of Cl_2 require = 1.75 × 3 = 5.25 mol of F_2

As, only 3.68 mol of F_2 is present, so F_2 is the limiting reagent.

c)

3 moles of F_2 form 2 moles of ClF_3

3.68 moles of F_2 will form = \frac{2}{3}  \times 3.68 = 2.45\ mol\ of\ ClF_3

d)

Cl_2 is present in excess.

3 moles of F_2 requires 1 mol of Cl_2

3.68 moles of F_2 will require = \frac{1}{3} \times 3.68 = 1.22\ mol\ of\ Cl_2

Cl_2 left = 1.75 -1.22 = 0.53 mol
