Why do we feel the need for conservation more today than our ancestors did

Chemistry
1 answer:
liraira [26]4 years ago
5 0

We feel a greater need for conservation as, we are facing lot of risk than our ancestors. Nowadays we are wasting so much of resources than our ancestors. For example : water. We are wasting water in so many ways such as leaving running taps without closing it. Natural resources are slowly vanishing by means of people who abuse it because they do not know the limitations of it. Abusing it can cause food shortage and also cause global warming. We need to conserve resources because it is the main source of our daily needs. Remember the 3 R's- reduce, reuse and recycle. Once it would be totally vanished our life would come to an end.

Hope this helps!

What is the boiling point elevation constant, Kb, of diethyl ether if 38.2 g of the nonelectrolyte benzophenone, C6H5COC6H5, dis
kakasveta [241]

Answer: the boiling point elevation constant is 1.73^0C/m

Explanation:

Elevation in boiling point is given by:

\Delta T_b=i\times K_b\times m

\Delta T_b=T_b-T_b^0= = Elevation in boling point

i= vant hoff factor = 1 (for non electrolyte)

K_b =boiling point constant = ?

m= molality

\Delta T_b=i\times K_b\times \frac{\text{mass of solute}}{\text{molar mass of solute}\times \text{weight of solvent in kg}}

Weight of solvent (diethylether)= 330 g = 0.33 kg

Molar mass of solute (benzophenone)= 182 g/mol

Mass of solute (benzophenone) = 38.2 g

(35.7-34.6)^0C=1\times K_b\times \frac{38.2g}{182g/mol\times 0.33kg}

K_b=1.73^0C/m

Thus the boiling point elevation constant is 1.73^0C/m
