how can a substance stay at a certain temperature even though it is being heated?

Answers

The temperature of a certain substance can be seen as the average speed of the atoms or molecules in that substance. In the liquid state of a substance the forces between the atoms or molecules are strong enough to keep them together, however with enough freedom to move, unlike in the solid state. If we would have a closer look at the surface of a liquid from sideways, we would see water molecules jumping out of the water and reentering it again. The lower the water temperature would be the lesser the amount of water molecules leaving the liquid phase would be. If water would be heated up and the temperature will reach 100 degrees C at normal atmospheric pressure, more water molecules would leave the water than reentering. Boiling has started. The temperature of the water remains at 100 degrees C, if the heating continues as the average speed of molecules will not increase, only the rate of molecules leaving the water will increase, until all the water in liquid state has been vapourized. The amount of heat needed to vapourize liquid water is called latent heat. Latent heat is a very important driving factor in the atmosphere and thus the weather.

How many total ions are in 2.95 g of magnesium sulfite?

Answers

Answer:

Approximately [tex]5.65 \times 10^{-2}\; \rm mol[/tex], which is approximately [tex]3.41 \times 10^{22}[/tex] particles.

Explanation:

Formula of magnesium sulfite: [tex]\rm MgSO_3[/tex].

Look up the relative atomic mass of [tex]\rm Mg[/tex]. [tex]\rm S[/tex], and [tex]\rm O[/tex] on a modern periodic table:

[tex]\rm Mg[/tex]: [tex]24.305[/tex].[tex]\rm S[/tex]: [tex]32.06[/tex].[tex]\rm O[/tex]: [tex]15.999[/tex].

The ionic compound [tex]\rm MgSO_3[/tex] consist of magnesium ions [tex]\rm {Mg}^{2+}[/tex] and sulfite ions [tex]\rm {SO_3}^{2-}[/tex].

Notice that [tex]\rm {Mg}^{2+}\![/tex] and [tex]\rm {SO_3}^{2-}\![/tex] combine at a one-to-one ratio to form the neural compound [tex]\rm MgSO_3[/tex]. Therefore, each [tex]\rm MgSO_3\![/tex] formula unit would include one [tex]\rm {Mg}^{2+}[/tex] ion and one [tex]\rm {SO_3}^{2-}[/tex] ion (that would be two ions in total).

Calculate the formula mass of one such formula unit:

[tex]\begin{aligned}&\; M(\mathrm{MgSO_3}) \\ = & \; 24.305 + 32.06 + 3 \times 15.999 \\ = & \; 104.362\; \rm g \cdot mol^{-1}\end{aligned}[/tex].

In other words, the mass of one mole of [tex]\rm MgSO_3[/tex] formula units (which includes one mole of [tex]\rm {Mg}^{2+}[/tex] ions and one mole of [tex]\rm {SO_3}^{2-}[/tex] ions) would be [tex]104.362\; \rm g[/tex].

Calculate the number of moles of such formula units in that [tex]2.95\; \rm g[/tex] of [tex]\rm MgSO_3[/tex]:

[tex]\begin{aligned}n&= \frac{m}{M}\\ &=\frac{2.95\; \rm g}{104.362\; \rm g \cdot mol^{-1}} \approx 2.82670 \times 10^{-2}\; \rm mol\end{aligned}[/tex].

There are two moles of ions in each mole of [tex]\rm MgSO_3[/tex] formula units. Therefore, that [tex]2.82670 \times 10^{-2}\; \rm mol[/tex] of [tex]\rm MgSO_3\![/tex] formula units would include approximately [tex]2 \times 2.82670 \times 10^{-2}\; \rm mol \approx 5.65\times 10^{-2}\; \rm mol[/tex] of ions.

Will group 2 elements gain electrons to bond with nonmetals in group 17 in a

1:2 ratio?

Will group 2 elements gain electrons to bond with nonmetals in group 16 in a

2:1 ratio?

Answers

Answer:

Will group 2 elements lose electrons to bond with nonmetals in group 17 in a

1:2 ratio?

Explanation:

Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.

Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.

The Princess cruise ship left San Francisco and traveled south for 8 hours at a speed of 30mph. What is the velocity of the ship? Round your answer to the hundreths place

Answers

Answer:

v = 300 mph due South.

Explanation:

Given that,

The Princess cruise ship left San Francisco and traveled south for 8 hours at a speed of 30mph.

We need to find the velocity of the ship. It can be calculated by total distance divided by total time taken.

Velocity is a vector quantity i.e. it has both magnitude and direction. On the other hand, the speed has only magnitude (scalar quantity).

In this case it is mentioned that the cruise is travelling south with a speed of 300 mph.

Hence, the velocity is 300 mph in South direction.
