The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
Because atomic number equals protons and electrons
8-electrons
8-protons
Protons+neutrons=mass
8+8=16 and 8+10=18
8-Neutrons for 16
10- Neutrons for 18
A.Weak
B.concentrated
C.dilute
D.strong
Answer: A - Weak
The oxidation state of iron may be 2,3 or 6 and the most common is 3 & this is our case, Fe^3+ can react with Oxygen (O2), which have fixed oxidation state (2), to form Fe2O3.
Two ions of iron and 3 ions of Oxygen with 2:3 ratio.
