This example is describing the Chromatography method.
To balance Ca + Cl2 = CaCl2 you'll need to be sure to count all of atoms on each side of the chemical equation.
Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Calcium + Chlorine gas.
Number of mole : mass/ molar mass
87g/ (2 x 16) = 2.719 mol
volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L
Answer:
Increases
Explanation:
As ice melts into liquid water, the kinetic energy of the particles increases.
This is because to melt ices, heat energy is supplied.
- The sum total of all the average speed of the particles in a substance is the heat energy.
- Heat is a form of kinetic energy.
- As more heat is added, the particles moves rapidly and the kinetic energy increase.
