Answer:

The volume of the ballon decreases as much as the temperature is much cooler.

Explanation:

In the problem, the pressure remains constant whereas the temperature decreases. Charles's law states that the temperature is directly proportional to the volume under constant volume.

As in the problem the pressure remains constant but the temperature decreases:

The volume of the ballon decreases as much as the temperature is much cooler.

A gas that has a volume of 28 liters, a temperature of 42°C, and an unknown pressure has its volume increased to 49 liters and i

kicyunya [14]

Answer:

7.35 atm

Explanation:

From the question we are given;

Initial volume, V1 as 28 L
Initial temperature, T1 as 42°C or 315 K
New volume. V2 as 49 L
New temperature, T2 as 27°C or 300 K
New Pressure, P2 as 4.0 atm

We are required to determine the initial pressure, P1

We are going to use the combined gas law...

According to the combined gas law,

$\frac{P_{1} V_{1} }{T_1} =\frac{P_2V_2}{T_2}$

Therefore, to get P1

$P_1=\frac{P_2V_2T_1}{V_1T_2}$

We get;

$P_1=\frac{(4.0)((49)(315)}{(300)(28)}$

$P_1=7.35$

Therefore, the initial pressure of the gas is 7.35 atm

Explanation:

I think pebbles because the pebbles can be different sizes and have bigger gaps in between them so the water will go through quicker.

Cloud [144]

Answer:

1 unshared pair of electrons

Explanation:

In order to draw the Lewis structure, we need to consider the octet rule: atoms tend to share electrons to complete their valence shell with 8 electrons. In the case of H, it has to complete a duet (2 valence electrons).

N has 5 valence electrons, so it has to share 3 pairs of electrons to reach the octet.

H has 1 valence electron, so it has to share 1 pair of electrons to reach the duet.

In the picture, we can see the resulting Lewis structure. There is 1 unshared pair of electrons on each nitrogen.
