Let's consider water.
Regardless of what form it turns into, the mass should remain the same.
It's the same H20.
Add some heat and it becomes water vapor,
cool it down a bit and it becomes ice.
if you make it just right, it becomes water again.
A chemical change would involve the one or more element(s) changing into a different solution all together.
It cannot be reversed unless you use electrolysis or some other method.
From the Dalton's law of partial pressures, the pressure of the hydrogen gas is 91.83 kPa.
<h3>What is partial pressure?</h3>
In a mixture of gases, the total pressure is the sum of the pressures of the individual gases in the mixture according to the Dalton's law of partial pressures.
In this case, the partial pressure of the hydrogen gas is Phydrogen, the partial pressure of water is Pwater and the total pressure is PT.
Hence;
Phydrogen = PT - Pwater
95 - 3.17 = 91.83 kPa

There would be 7- this would be the process of meiosis, which would result in 4 haploid cells (each would have half the number of chromosomes as the parent (or 7), as meiosis is sex cell division) the other type of cell division is called mitosis and results in two daughter cells identical to the parent cell (2 cells, each with 14 chromosomes)
Answer:
38.1 L
Explanation:
Data given:
initial volume V1 of a gas = 3 L
initial Temperature T1 of a gas = 21 °C
convert Temperature to Kelvin
T1 = °C +273
T1 = 21°C + 273 = 294 K
final Temperature T2 of a gas = 100°C
convert Temperature to Kelvin
T2 = °C +273
T2 = 100°C + 273 = 373 K
final Volume V2 of a gas = ?
Solution:
This problem will be solved by using Charles' law equation at constant pressure.
The formula used
V1 / T1 = V2 / T2
As we have to find out Volume, so rearrange the above equation
V2 = V1 x T2 / T1
Put value from the data given
V2 = 3 L x 373 K / 294 K
V2 = 38.1 L
So the final Volume of a gas = 38.1 L
