<u>Answer:</u> The new pressure will be 101.46 kPa.
<u>Explanation:</u>
To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.
The equation given by this law is:
where,
are initial pressure and temperature.
are final pressure and temperature.
We are given:
By using conversion factor: 
Putting values in above equation, we get:
Hence, the new pressure will be 101.46 kPa.
First one is a
the
second one is b
The answer is <span>D.when the aim is to show electron distributions in shells. This is because there are some instances when elements don't possess a regular or normal electron configuration. There are those who have special electron configurations wherein a lower subshell isn't completely filled before occupying a higher subshell. It is best to visualize such cases using the orbital notation.</span>
Answer:
There are 3 significant figures in 675000
Explanation:
The rules for significant figures:
- Non zero digit (from 1 upward) are always significant
- Trailing zero are not significant
- but zero in the presence of decimal are significant
In this case, the trailing zeros are not significant thus only the first 3 non zero digit are significant.
