Answer:
The large relative distances between particles in a gas means that there is considerable empty space between the particles.
The assumption that particles in a gas are relatively far apart explains gas compressibility.
Compressibility is a measure of how much the volume of matter decreases under pressure.
Energy is released by a gas when it is compressed
Explanation:
The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.
Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
Answer: (P2/P1)=(T2/T1)
(P2/1200.0kPa)=(387/283)
P2=(387K/283K) * (1200kPa)
P2= 1641kPa
Explanation:
Answer:
4.767 grams of KCl are produced from 2.50 g of K and excess Cl2
Explanation:
The balanced equation is
2 K+ Cl2 --->2 KCI
Here the limiting agent is K. Hence, the amount of KCl will be calculated as per the mass of 2.50 gram of K
Mass of one atom/mole of potassium is 39.098 grams
Number of moles is 2.5 grams = 
So, 2 moles of K produces 2 moles of KCL
0.064 moles of K will produces 0.064 moles of KCl
Mass of one molecule of KCl is 74.5513 g/mol
Mass of 0.064 moles of KCl is 4.767 grams
Elements with atomic number greater than 92(Atomic number of Uranium) are known as transuranium element.
Cm - Curium is a transuranium element as its atomic number is 96.
In a chemical change, a new substance is made, like when you burn a candle. In a physical change, no new substance is made, like when water turns to ice.
