1-Bromopropane is treated with each of the following reagents. Draw the major substitution product if the reaction proceeds in g
sammy [17]

Answer:

Explanation:

If we look at the structure of 1-Bromopropane; we will see that it is a derivative of alkane family by the the substitution of an alkyl group. The position of the Bromine in the propane is 1, making 1-Bromopropane  a primary alkyl-halide.

Primary alkyl - halide undergo SN2 mechanism. This nucleophilic reaction needs to be a strong alkyl halide , such as 1-Bromopropane used  otherwise it will result to a reactive mechanism if a weak electrophile is used.

However, the critical and the main objective here is to Draw the major substitution product if the reaction proceeds in good yield. If no reaction is expected or yields will be poor, draw the starting material in the box. If a charged product is formed, be sure to draw the counterion.

The attached diagrams portraying this notions is shown in the attached file below.

What is meant by saying that the latent heat of vaporization of water is 22. 5×10^5 j/kg.
andrey2020 [161]

It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.

Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.

Boiling point of the water is 100°C.

Joule (J) is the standard unit for energy (in this example heat).

Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

If 5.0 moles of C3H8 react, how many molecules of water are formed?
Lady_Fox [76]
 <span>Propane is C3H8 

The balanced equation is: 
C3H8 + 5 O2 --> 3 CO2 + 4 H2O 
From the balanced equation you can see that for each mole of C3H8 you obtain 4 moles of H2O. 

moles H2O = 5.0 moles C3H8(4 moles H2O/1 mole C3H8) = 20 moles H2O formed 

Use Avogadro's number to find the number of molecules. 
molecules H2O = 20 moles H2O(6.02 x 10^23 molecules/1 mole) = 1.20 x 10^25 H2O molecules</span><span>
