Answer:
a. .125 mol b. 7.25g
Explanation:
a. To get the moles multiply the volume by the molarity.
.5L*.25M=.125mol NaCl
b. The molar mass is provided so multiply the moles by the molar mass to get the amount of grams of nacl.
.125mol*58molar mass=7.25g nacl to make the solution
Allowing organic matter to decompose
Answer:
A. The rate of reaction will increase or go up
B. The rate of reaction will decrase or go down.
Explanation:
Increasing the temperature will make the gas particles move faster. Faster movement will increase rate of collision between particles to cause a reaction. Decreasing the temperature will cause the opposite to happen.
Changing the number of NEUTRONS makes an atom stable or unstable and creates different isotopes of the same element with a different ATOMIC MASS
