Answer:

The organic compund that is the least likely to be used as an organic solvent is:

aldehyde

Explanation:

The reason behind this is that even though aldehydes are used in the perfumery industry. They are not very good solvents because the majority of them are hazardous. Only a minimal fraction of them can be tolerated by organisms and that can even make them have weak poisoning reactions. However, using them as solvents in bigger quantities will make them hazardous for organisms considering their high concentration of ketones.

Answer:

$\triangle G= -6.7 KJ/mol$

Explanation:

From the question we are told that:

Chemical Reactions:

X=A⇌B,ΔG= 14.8 kJ/mol

Y=B⇌C,ΔG= -29.7 kJ/mol

Z=C⇌D,ΔG= 8.10 kJ/mol

Since

Hess Law

The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the number of steps taken.

Therefore

Generally the equation for the Reaction is mathematically given by

$T = +1 * X +1 * Y +1 *Z$

Therefore the free energy, ΔG is

$\triangle G=1 * \triangle G*X +1 * \triangle G*Y +1 * \triangle G *Z$

$\triangle G= +1 * (14.9) +1 * (-29.7) +1 * (8.10)$

$\triangle G= -6.7 KJ/mol$

A piece of glass has a temperature of 83˚C. Liquid that has a temperature of 43˚C is poured over the glass, completely covering

Lerok [7]

Answer: The specific heat of the liquid is $2520J/kg^0C$

Explanation:

$heat_{absorbed}=heat_{released}$

As we know that,

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

.................(1)

where,

q = heat absorbed or released

= mass of glass = x kg

= mass of liquid = x kg

= final temperature =

$T_1$ = temperature of glass = $83^oC$

$T_2$ = temperature of liquid = $43^oC$

$c_1$ = specific heat of glass = $840J/kg^0C$

$c_2$ = specific heat of liquid= ?

Now put all the given values in equation (1), we get

$-[(x\times 840\times (53-83)]=x\times c_2\times (53-43)$

$c_2=2520J/kg^0C$

Therefore, the specific heat of the liquid is $2520J/kg^0C$

Answer:

I might be wrong i'm not sure

Explanation:

Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.
