Water heater contains 56 part a how many kilowatt-hours of energy are necessary to heat the water in the water heater by 25 ?c?

DochEvi [55]

Answer is: 550,021 kWh of energy is needed to heat the water

V(water) = 51 gal = 51·3,78 = 189,3 L.

ΔT(water) = 25°C.

d(water) = 1000 g/L.

m(water) = V(water) · d(water)

m(water) = 189,3 L · 1000 g/L

m(water) = 189300 g.

Q = m(water) · ΔT(water) · C(water)

Q = 189300 g · 25°C · 4,184 J/°C·g

Q = 19800780 J = 19800,78 kJ ÷ 3600 = 550,021 kWh.

bonufazy [111]

Answer:

p-bromobenzyl cyanide

Explanation:

In a nucleophilic substitution, a nucleophile replaces a leaving group (halide ion) from a carbon atom, using a lone pair of electrons to form a new bond with the carbon atom.

In this reaction, the cyanide ion is the nucleophile and the bromide ion is the leaving group.

This nucleophilic substitution is an example of an SN₂ reaction. This reaction occurs in a single step, where bonds break and form simultaneously.

In this product, the nucleophile occupies the opposite stereochemical position to the original position of the leaving group. This result is known as an inversion of the carbon atom configuration.
