In which substance do the molecules have the strongest attractions to one another?

1 answer:

8 0

The substance that the molecules have the strongest attractions to one another is the sugar, a solid. The answer is letter A. The solid has a more definite shape and volume. The particles are locked into place. It cannot be further compressed due to the bond that exists between the molecules. The kinetic energy of the molecules is close to none because the molecules are so close and so compact with each other.

The heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only A. TRUE B. FALSE

Zinaida [17]

Answer: The given statement is false.

Explanation:

Heat flux is defined as the flow of heat or energy per unit time in per unit area. S.I. unit of heat flux is watts per square meter.

Heat flux is represented by the symbol $\phi _{q}$ .

So, it means heat flux is not measured in watts only as it includes per unit area also.

Therefore, we can conclude that the given statement heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only, is false.

What is the mass-action expression Qc for the following chemical reaction:Zn(s)+2Ag+(aq) â‡Œ Zn+2(aq)+2Ag(s) a. [Zn-2]/[Ag-]b. [

sattari [20]

Answer : The expression for reaction quotient will be :

$Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}$

Explanation :

Reaction quotient (Qc) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given redox reaction is :

$2Ag^{+}(aq)+Zn(s)\rightarrow 2Ag(s)+Zn^{2+}(aq)$

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

The expression for reaction quotient will be :

$Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}$
