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.
Answer:

Explanation:
Given
Compound: 
Required
Determine the equivalent mass
In the above compound, we have: 2 Al and 3 (O)
The atomic mass of Aluminium is:

The atomic mass of Oxygen is:

So, the equivalent mass is:



H3PO3 because this <span>compound dissolved in water will give you that formula</span>
True
Explanation:
Ionic compounds are chemical compounds that dissociates into positive and negative ions and are globally neutral due to the charge balance. They are made up of metals and non-metals.
- Ionic bonds are formed between two kinds of atoms having a large electronegativity difference.
- It is usually between metals and non-metals.
- The formation of this bond type involves the transfer of electrons from the less electronegative atom such that the two kinds of atoms now have completely filled outer shell like the noble gases.
- This transfer makes the metal positively charged while the non-metal becomes negatively charged.
- The atoms forms ions that are oppositely charged.
- The charges are balanced out leaving a net neutral compound.
- The electrostatic force of attraction between these ions is the ionic or electrovalent bond.

Answer:
45g of NaCl x 1mole of NaCl/58.5g
= 0.769moles of Nacl
Now Looking at the equation
1mole of Nacl produces 1mole of AgCl
so
0.769mole of NaCl will produces the same Mole of AgCl(0.769)
So the Moles of AgCl produced = 0.769
Recall
Mole = Mass /Molar Mass
Mass = Mole x Molar Mass
Molar Mass of AgCl =108 + 35.5 = 143.5
Mass of Agcl = 0.769 x 143.5
=110.35g of AgCl
