Answer: 532.836 cubic centimeters

Explanation:

Given : The volume of a rectangular solid is the product of its length, width, and height.

Then, the  volume of a rectangular solid with length 11.4 cm, width 12.3 cm, and height 3.8 cm will be :-

\text{Volume}=11.4\times12.3\times3.8

Simplify ,

\Rightarrow\ \text{Volume}=532.836\ cm^3

Hence, the volume of the given rectangular prism = 532.836 cubic centimeters

The chemical formula of ordinary sugar is C12H22O11. Calculate the mass of 7.35 mol of sugar.
ch4aika [34]

First, you need to find the mass of 1 mol of sugar. Mass, or molar mass, can simply be found by adding the masses of the individual elements. These are given to you on the periodic table.

C_{12}H_{22}O_{11}

12 x 12.011 grams (molar mass of Carbon) = 144.132 g

22 x 1.008 grams (molar mass of Hydrogen) = 22.176 g

11 x 15.999 grams (molar mass of Oxygen) = 175.989 g

Add all of the pieces together.

144.132 g + 22.176 g + 175.989 g = 342.297 grams

So, if one mole has 342.297 grams, then 7.35 of that amount will be your answer.

342.297 g/mol x 7.35 mol =  2,515.88 grams

Dentify the reagents used to carry out the chlorination of benzene. a. cl2/ccl4 b. cl2/fecl3 c. cl2/nacl d. both b and c e. a, b
algol13

The reagents which are used to carry out the chlorination of benzene are   cl2/fecl3 and cl2/nacl

Chlorination is the process of disinfecting drinking water by introducing chlorine to eradicate viruses, germs, and parasites. To get drinking water with safe levels of chlorine, various techniques can be utilized. Chlorination is the technique of disinfecting and eradicating bacteria from drinking water by adding chlorine to it.

To get drinking water with safe levels of chlorine, various techniques can be utilized. Chlorine can be found as solid calcium hypochlorite (Ca(OCl)2), sodium hypochlorite solution (NaOCl), or compressed elemental gas. Chlorine is added to water as part of the chlorination process, however the chlorinating substance need not be pure chlorine.

Artemon [7]

The molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol, Option D is the correct answer.

<h3>What is enthalpy of Combustion ?</h3>

The energy released when a fuel is oxidized by an oxidizing agent is called enthalpy of Combustion.

It is given that

a 1.0 g sample of magnesium is burned to form MgO. in doing so, 25.5 kj of energy are released.

Molecular weight of Magnesium = 24.35g

24.35 g makes 1 mole of Mg

1g = 1/24.35

For 0.04 moles  25.5 kJ is released

for 1 mole 25.5 *1/.04

= 620 kj/mol

Therefore the molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol.
