The answer is Oxygen ions & Chloride ions. Although<span> Dissolved Oxygen (DO) can not interact with the Lead, Orthophosphates have to be added continually or the barrier breaks down. If the barrier does break down, DO combines with Lead atoms, oxidizing them. It allows Lead to drain into drinking water. Once oxidized, Lead dissolves into the water instead of sticking to the pipe. </span>Flint’s water treatment plant did not add
orthophosphates, allowing the pipes to corrode, and Lead quickly contaminated the drinking water. Additionally, Flint River water had high levels of chlorides, which accelerate corrosion.<span>

Answer:
6.7 x 10²⁶molecules
Explanation:
Given parameters
Mass of CO₂ = 4.9kg = 4900g
Unknown:
Number of molecules = ?
Solution:
To find the number of molecules, we need to find the number of moles first.
Number of moles = 
Molar mass of CO₂ = 12 + 2(16) = 44g/mol
Number of moles = 
= 111.36mole
A mole of substance is the quantity of substance that contains the avogadro's number of particles.
1 mole = 6.02 x 10²³molecules
111.36 moles = 111.36 x 6.02 x 10²³molecules = 6.7 x 10²⁶molecules
It will belong to the metals because metals bond with nonmetals like chlorine to form ionic compounds
Answer:
Explanation:
2HCl = H₂ + Cl₂
2 mole 1 mole 1 mole
73 gram HCl = 73 / 36.5 = 2 mole of HCl
2 moles of HCl will produce 1 mole of chlorine gas .
At STP , one mole of chlorine gas has volume equal to 22.4 litre .
