Objects that can bew seen only under magnification

1 answer:

4 0

The answer is (D) microscopic. You can remember this, because the name is very close to "microscope," an instrument used to greatly magnify and observe tiny organisms and objects.

Answer:

* $W=1142.86Joule$

* $Q=997.7J$

* $H=2140.5J$

Explanation:

From the question we are told that:

Temperature $T=337K$

Pressure $P=(60-55)Pa*10^5$

Volume $V=(1.6-1.4)m^3*10^{-3}$

Generally the equation for gas Constant is mathematically given by

$\frac{P_2}{P_1}=\frac{V_1}{V_2}^n$

$\frac{55*10^5}{60*10^5}=\frac{1.4*10^{-3}}{1.6*10^{-3}}^n$

$n=0.65$

Therefore

Work-done

$W=\int{pdv}$

$W=\frac{55*10^5*1.6*10^{-3}*60*10^5*1.4*10^{-3}}{1-0.65}$

$W=1142.86Joule$

Generally the equation for internal energy is mathematically given by

$Q=mC_vdT\\\\Q=\frac{3*1*3.314*16}{1.4-1}$

$Q=997.7J$

Therefore

$H=Q+W$

$H=997.7J-11.42.9$

$H=2140.5J$

Choose the statement below that is TRUE. A weak acid solution consists of mostly insoluble acid molecules. The term 'strong elec

lora16 [44]

Answer: Option (A) is the correct answer.

Explanation:

A weak acid is defined as a substance which dissociates partially into a solvent. This also means that most of the molecules of a weak acid solution remain insoluble in nature.

A solution in which solute particles completely dissociate into ions in a solvent is known as a strong electrolyte.

Whereas a solution in which solute particles partially dissociate into ions is known as a weak electrolyte.

A molecular compound is a covalent compound and as like dissolves like. So, molecular compounds are not soluble in polar solvent like water.

Therefore, we can conclude that the true statement is weak acid solution consists of mostly insoluble acid molecules.
