50 degrees Fahrenheit is equal to about 10 degrees Celsius. Hope this helps!
Answer: The new volume is 53.3 ml
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 50.0 kPa
= final pressure of gas = 80.0 kPa
= initial volume of gas = 80.0 ml
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The new volume is 53.3 ml
Explanation:
We have to find the number of moles of N₂ that are present in a sample that has a volume of 40.0 L at STP.
STP means Standard Conditions of Temperature and Pressure. These conditions are 273.15 K and 1 atm. We know that 1 mol of N₂ will occupy 22.4 L. We can use that ratio to find the answer to our problem.
1 mol of N₂ = 22.4 L
moles of N₂ = 40.0 L * 1 mol/(22.4 L)
moles of N₂ = 1.79 mol
Answer: 1.79 moles of nitrogen are present.
The solid water begins to change into liquid water when the ice molecules<span> start to move around. Another way to say that a substance changes from the solid state to the liquid state is to say it </span>melts<span>. Te </span>ice<span> continues to </span>melt<span> as more </span>ice molecules<span> get enough energy to move around.</span>
