Answer:

A heat exchanger is device which is designed to transfer heat from one matter to another. In nuclear power plants, these heat exchangers are used to pass heat from primary system to the secondary system. In the process they produce steam from water, they are also called steam generators or pressurized water reactors.

nasty-shy [4]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The consumption of the reactant benzophenone and the production of triphenylmethanol can be detected using their IR absorption spectrum

This reaction is shown on the second uploaded image

The reactant benzophenone is a compound which contains a carbonyl functional group, and the stretching frequency of C=O bond has a high absorption at around $1680 \ cm^{-1}$ and frequency band of this wavelength is absent in triphenylmethanol.

in the same vain the product triphenylmethanol is a compound which contains a hydroxyl (OH) functional group, and the stretching frequency of O-H bond has a high absorption at around $3474 \ cm^{-1}$ and frequency band of this wavelength is absent in benzophenone.

To use infrared spectroscopy to show that the reaction is occurring is to show the disappearance of the $1680 \ cm^{-1}$ frequency band which indictes the consumption of benzophenone and the appearance $3474 \ cm^{-1}$ frequency band which indictes the formation of triphenylmethanol

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calcu

Bad White [126]

Answer:

<h3>The answer is 8.40 g/mL</h3>

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 = 56.4 - 50 = 6.4 mL

We have

$density = \frac{53.78}{6.4} \\ = 8.403125$

We have the final answer as

Hope this helps you

A reaction occurs in a calorimeter, resulting in the starting and final temperatures shown below. What can you say about the rea

ELEN [110]

"The reaction is exothermic and ΔH is negative" can be understood about the reaction and the enthalpy change (ΔH) during the reaction.

<u>Option: D</u>

<u>Explanation:</u>

When the reaction is positive, the process becomes endothermic, i.e. heat appears to be consumed by the system because the reaction products are more enthalpic than the reactants. When the reaction is negative, on the other hand, the process is exothermic, which is the total decrease in enthalpy is caused by heat production. Here the initial temperature is 21.0 C but increase in final temperature to 38.8 C, because if some processes require heat, others must give off heat when they take place.

A mineral consisted of 29.4% calcium, 23.5% sulfur and 47.1% oxygen. What is the empirical formula?

inessss [21]

Step one calculate the moles of each element
that is moles= % composition/molar mass
molar mass of Ca = 40g/mol, S= 32 g/mol , O= 16 g/mol

moles of Ca = 29.4 /40g/mol=0.735 moles, S= 23.5/32 =0.734 moles, O= 47.1/16= 2.94 moles

calculate the mole ratio by dividing each mole with smallest mole that is 0.734
Ca= 0.735/0.734= 1, S= 0.734/0.734 =1, O = 2.94/ 0.734= 4
therefore the emipical formula = CaSO4
