Boil it. Kinetic energy is energy of motion and hot water moleculues move more
Decay is a type of degradation reaction and thus is considered a first order reaction. thus the formula goes like this.
rate constant= 0.693/half life
so here...
rate constant= 0.693/1620 year^-1
Answer:
The baseball is thrown twice as fast as the softball in the same direction.
Explanation:
A "FORCE" is required to cause acceleration or cause an object to move.
Answer:
17.83M
Explanation:
Given parameters:
Mass of KCO₂ = 1.5kg
Volume of water = 850mL
Unknown:
Molarity of solution = ?
Solution:
Molarity is defined as the number of moles per unit volume. It is the number of moles of solute in a given volume of solution.
Molarity = 
Number of moles of solute = 
Molar mass of KCO₂ = 39 + 12 + 3(16) = 99g/mol
Number of moles =
= 15.15moles
850mL : gives 0.85L
Molarity =
= 17.83M
