Using your knowledge of thermochemistry, what equation is appropriate to calculate the heat produced from the HCl-NaOH reaction?
suter [353]

Answer:

Neutralization equation:

HCl + NaOH  → NaCl + H₂O + Heat

Heat would calculated through,

Q = m . c. ΔT

Explanation:

When aqueous sodium hydroxide and hydrochloric acid react with each other a neutralization reaction occur. It produces water and salt. The salt would be sodium chloride.

Chemical equation:

HCl + NaOH  → NaCl + H₂O + Heat

The heat produces can be calculated through the given formula.

Q = m . c. ΔT

Q = amount of heat produces

m = total mass of solution

ΔT = change in temperature of solution

C = specific heat capacity of solution

As the mostly solutions are water so we take the specific heat capacity of water which is 4.186 j/g .°C

A rock that has a mass if 180 grams dropped in a graduated cylinder that was originally filled to 52ml; it now reads 62ml. What
Vlad [161]

Answer:

<h2>18 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

volume = final volume of water - initial volume of water

volume = 62 - 52 = 10 mL

From the question we have

density =  \frac{180}{10}  \\

We have the final answer as

<h3>18 g/mL</h3>

Hope this helps you

A soda is made of 5% CO2 gas, 10% powdered drink mix, and 80% water.
Aleonysh [2.5K]

Answer:

Water is a solvent, and CO2 gas and the powdered drink mix are both solutes.

Explanation:

In order to successfully answer this question, we need to remember that solutions consist of solutes and solvents.

Solutes are components of solutions that are dissolved (typically ionic salts if we have a polar solvent), while solvents are fluids (usually liquids) that provide a medium for the solutes to dissolve (water is the most common polar solvent for ionic salts, for example).

As a general rule, solvent is used in great excess, that is, it makes the greatest percentage in terms of mass of a particular solution.

Applying the theory above for this problem, notice that the greatest percentage of this solution belongs to water, besides, water is a common solvent in general. Thus, it is our solvent.

Also, solution would only have one solvent and one or several solutes. This leaves the two other components, carbon dioxide and powdered drink mix, as our solutes, as they have a lower percentage than our solvent.

Write the structure of the product that would be formed from the S(
prisoha [69]

Answer:The product formed on reaction with hydroxide ion as nucleophile is 2R-hexane-2-ol.

The product formed on reaction with water would be a 50:50 mixture of

2S-hexane-2-ol. and 2R-hexane-2-ol.

Explanation:

2S-iodohexane on reactiong with hydroxide ion would undergo SN² substitution reaction that is substitution bimolecular. Hydroxide ion has a negative charge and hence it is a quite good  nucleophile .

The rate of a SN² reaction depends on both the substrate and nucleophile . Here the substrate is a secondary carbon center having Iodine as a leaving group.SN² reaction  takes place here as hydroxide ion is a good nucleophile and it can attack the secondary carbon center from the back side leading to the formation of 2R-hexane-2-ol.

In a SN² reaction since the the nucleophile attacks from the back-side so the product formation takes place with the inversion of configuration.

When the same substrate S-2-iodohexane undergoes a substitution reaction with water as a nucleophile then the reaction occurs through (SN¹) substitution nucleophilic unimolecular mechanism .

The rate of a SN¹ reaction depends only on the nature of substrate and is independent of the nature of nucleophile.

The SN¹ reaction is a 2 step reaction , in  the first step leaving group leaves leading to the formation of a carbocation and once the carbocation is formed then any weaker nucleophile or even solvent molecules can attack leading the formation of products.

In this case a secondary carbocation would be generated in the first step and then water will attack this carbocation to form the product in the second step.

The product formed on using water as a nucleophile would be a racemic mixture of R and S isomers of hexane -2-ol in 50:50 ratio. The two products formed would be 2R-hexane-2-ol and 2S-hexane-2-ol.

Kindly refer the attachment for reaction mechanism and structure of products.
