it causes bacteria and viruses from human and animal waste, and a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, and typhoid.
Answer:
So on dissolution, it will produce magnesium hydroxide which is a base and the solution will be basic in nature. So it will change the color of red litmus paper to blue, and blue will remain the same.
Explanation:
It’s B the high mass stars
Powdered aluminum serves the reducing agent for this reaction. Aluminum powder is known as a powerful reducing agent. <span>Iron(iii) ions would have greater electron affinity as compared to a metallic aluminum thus it would easily gain electrons from aluminum making it less positive in this case formed into a neutral atom. </span><span>The chemical reaction is </span>
<span>Fe2O3 + 2Al = Al2O3 + 2Fe.
</span>
<span>Oxygen in the oxide compound does not participate in this redox reaction, as it is not changed </span>chemically<span>. Fe2O3 is an ionic compound which has of Fe[3+] ions and O[2-] ions. So, the net ionic reaction would be</span>
<span>Fe3+ + Al + 3O2- = Al3+ + Fe + 3O2- </span>
<span>The ionization energy of aluminum is greater than that of iron, so the said reaction would generate large amount of heat which is needed in welding.</span>
Over time, the particles in the suspension would settle to the bottom when the movement keeping them suspended fades away. This will not happen with a solution.
