Answer:

Explanation:
Hello!
In this case, according to the Avogadro's number, it is possible to compute the atoms of Kr in 2.00 moles as shown below:

Best regards!
Its a chemical reaction because both are affected by the reaction and changed. hope this helps (ू• o •ू )
Almost all catalysts work by lowering the activation energy of the reaction with no change in the free energy of the reaction
- So in this case we can say that palladium reduce automobile pollution by catalyzing the reaction between un-burned hydrocarbons and oxygen :
D. by decreasing the activation energy
Answer:
yes
Explanation:
it started moving North 5 m/s
kilograms are the unit that measures mass
