The book will serve as a flat surface on which you
will later place additional weights. It has its own
mass, which you need to measure.
Zero the balance. Place the book on the balance.
Measure the mass to the nearest gram (1 g).
498 g
In this experiment, you will measure all masses in
kilograms. Convert the book’s mass to kilograms.
0.498 kg
Hi friend,
If The activation energy is reduced then the rate of chemical reaction will also be decreased.
Hope it helps.!

The relationship between n and the total number of orbitals in a main energy level is n^2.
According to the wave mechanical model, the orbital is a region in space where there is a high probability of finding an electron. In every energy level, a number of orbitals are possible.
The number of possible orbitals in an energy level is given by n^2. For instance, for the energy level, n=2, the total number of possible orbitals is (2)^2 or 4 orbitals.
