If the volume of oxygen gas is 259 cm3 at 112 kPa, what would the volume be at 101.3 kPa?

NARA [144]

Answer:

<h3>The answer is 286.36 cm³</h3>

Explanation:

In order to find the volume be at 101.3 kPa we use Boyle's law which is

$P_1V_1 = P_2V_2$

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the final volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question

P1 = 112 kPa = 112000 Pa

V1 = 259 cm³

P2 = 101.3 kPa = 101300 Pa

We have

$V_2 = \frac{112000 \times 259}{101300} = \frac{29008000}{101300} \\ = 286.3573543...$

We have the final answer as

Hope this helps you

Most chemical changes are _________ and cannot be reversed .

Pachacha [2.7K]

Answer:

irreversible changes

Explanation:

Most chemical changes are permanent and cannot be reversed. That is because a chemical change involves changing the molecular composition which can't be reversed. A common example of a chemical change would be burning wood. The wood burning into ash is changing the molecular composition of the wood transforming it to ash. Now can ash be changed back into wood? No, it is a "irreversible change."

Hope this helps.

What type of bond allows heat and electricity to move freely throughout the material?

OLga [1]

That would be an ionic bond since it has electrons to spare, rather than a convalent bond where all the electrons are taken up thus it is not a good conductor

Please Help 8-9!!!!!!!

The labeled diagram is given in the image attached.

As it can be seen from the image that freezing is when energy is removed from the system at 0 ⁰ while melting is when energy is added at 0⁰.

Also when energy is added at 100⁰C, it causes boiling while when it is removed at 100⁰C, it causes condensation.

Melting point of water is 0⁰C while boiling point is 100⁰C
