The equation, DF + heat Imported Asset D + F, is an example of an endothermic reaction.

zvonat [6]

The answer is TRUE.

If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.

Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.

Silver chloride is virtually insoluble in water so that the reaction appears to go to completion. How many grams of solid NaCl m

masya89 [10]

Answer:

0.535 g

Explanation:

The reaction that takes place is:

NaCl + AgNO₃ → AgCl + NaNO₃

First we calculate how many AgNO₃ moles are there in 25.0 mL of a 0.366 M solution, using the definition of molarity:

Molarity = moles / liters

moles = Molarity * liters

Converting 25.0 mL to L ⇒ 25.0 / 1000 = 0.025 L

moles = 0.366 M * 0.025 L = 0.00915 mol AgNO₃

Then we convert AgNO₃ moles into NaCl moles:

0.00915 mol AgNO₃ * $\frac{1molNaCl}{1molAgNO_3}$ = 0.00915 mol NaCl

Finally we convert NaCl moles into grams, using its molar mass:

0.00915 mol NaCl * 58.44 g/mol = 0.535 g
