Correct Answer: option 4: <span>E and D show that the energy of the products is less than that of the reactants.

Reason: 
For the reaction:          Q + R      </span>→        N + M
<span>                                  (reactant)             (product)

From the graph, it is clearly evitable that E represent energy of reactant, while D represents energy of products. Also, value of D is less as compared to E. This signifies that, products (N+M) has less energy as compared to reactants (Q+R). Also, the reaction is exothermic in nature.

<span>Answer: the fourth option: E and D show that the energy of the products is less than that of the reactants.


Explanation:
</span><span />

<span>The graph shows how the energy of the species (vertical axis) changes as the reaction progress (horizontal axis).
</span><span />

<span>We can see each option:
</span><span />

<span>1) A and C show that the reaction enthalpy is less than the activation energy.
</span><span />

<span>FALSE: C is the energy difference between products and reactants, and that is the enthalpy of the reaction, while C is the activation energy (the peak of the curve).


2) G and E show that this reaction is an endothermic process with heat release.
</span><span />

<span>FALSE: since G is below E, the final energy is less than the initial energy, meaning that the reaction released energy and, consequently, the reaction is exhotermic.


3) B and F show that the activated complex has less energy than the reactants.
</span><span />
FALSE
<span>The activated complex is at the peak of the curve, so it hass more energy than the reactants.
</span><span />

<span>4) E and D show that the energy of the products is less than that of the reactants.

</span><span>TRUE: indeed D is below E meaning the the energy of the products (D) is less than the energy of the reactants (E).</span>

How many grams of calcium chloride will be produced when 29.0 g of calcium carbonate is combined with 15.0 g of hydrochloric aci
horsena [70]

Answer:

22.7 g of CaCl₂ are produced in the reaction

Explanation:

This is the reaction:

CaCO₃ +  2HCl  →  CaCl₂  + CO₂  +  H₂O

Now, let's determine the limiting reactant.

Let's divide the mass between the molar mass, to find out moles of each reactant.

29 g / 100.08 g/m = 0.289 of carbonate

15 g / 36.45 g/m = 0.411 of acid

1 mol of carbonate must react with 2 moles of acid

0.289 moles of carbonate will react with the double of moles (0.578)

I only have 0.411 of HCl, so the acid is the limiting reactant.

Ratio is 2:1, so I will produce the half of moles, of salt.

0.411 / 2 = 0.205 moles of CaCl₂

Mol . molar mass = mass → 0.205 m . 110.98 g/m = 22.7 g

sergey [27]

Answer:

occur if two of the ions form an insoluble ionic compound, which precipitates out of solution

Explanation:

When two ionic compounds are dissolved in water, a double replacement reaction takes place if two of the ions form an insoluble ionic compound, which precipitates out of solution. In double displacement reaction ions switch partners. And hence, produce an insoluble precipitate.
