In balancing reactions, the number of atoms on each side should be of equal number. It is the most important rule in reactions. Also, we should know the correct substances involved in the reaction. We do as follows:
2K + MgBr2 = 2KBr + Mg
Hi!
The answer is breathing.
Protozoans are organisms that can multiply themselves in humans, and serious infections can develop from one organism. The most frequently transmission methods are contaminated food or fecal contact. Dog bites inoculate bacteria into deep tissue, and they also serve as a transmission method.
Breathing is not considered to be likely to transmit protozoan infection because protozoans rarely develop in the respiratory tract.
Yes becuase it says it maintains its velocity if it is moving or at rest

Explanation:
Given:
Formula units of FeCl₃ = 8.65 x 10²³ formula units
Unknown:
Mass of the FeCl₃ = ?
Solution:
The formula unit is the same as the amount of subatomic particles in an atom.
1 mole of a substance = 6.02 x 10²³ formula units
For 8.65 x 10²³ formula units; the number of moles;
Number of moles = 
= 1.44moles
Now to find the mass of FeCl₃;
Mass of FeCl₃ = 1.44 x 162.2 = 233.1g
