Can two organisms belong to the same family but different classes? Explain.

slega [8]

This information is correct. This is because the order of classification is domain, kingdom, phylum, class, order, family, genus, species. Since class comes before family, the two organisms could be in the same class, but then when you specify further, they could be in different families.

When a pendulum swings, if it is not continuously pushed it will not stop eventually because some of its energy is changed into.

Vladimir79 [104]

Well, there is kinetic energy when the object is in motion. But it will stop eventually because that energy is converted into thermal energy, or heat.

Given the chemical reaction: Hg2+(aq) + Cu(s) + Hg(s) + Cu2+(aq)

Pavel [41]

Answer: When the reaction reaches equilibrium, the cell potential will be 0.00 V

Explanation:

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.

The standard emf of a cell is related to Gibbs free energy by following relation:

$\Delta G=-nFE^0$

The Gibbs free energy is related to equilibrium constant by following relation:

$\Delta G=-2.303RTlog K$

For equilibrium $\Delta G=0$

Thus $0=-nFE^0$

$E^0=0$

Thus When the reaction reaches equilibrium, the cell potential will be 0.00 V

How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?

Crank

Answer:

The answer is " $\bold{6.26 \times 10^{24} \ molecules \ NH_3}\\\\$ "

Explanation:

1-mole molecules as per Avogadro number $= 6.02 \times 10^{23} \ molecules\\\\$

1-mole $NH_3 \to 6.02 \times 10^{23} \ molecules\\\\$

$10.4 \ moles \ of \ \ NH_3 :$

$\to \frac{ 6.02 \times 10^{23} \ molecules }{ 1 \ mole\ NH_3} \times 10.4 \ mole \ NH_3\\\\ \to 6.02 \times 10^{23} \ molecules \times 10.4\\\\\to 62.608 \times 10^{23} \ molecules \\\\\to 6.26 \times 10^{24} \ molecules \ NH_3\\\\$
