You are working in a lab on your magnetic levitation experiment. You are standing directly in front of two magnets. Another scientist near you has a malfunction with their equipment and beta radiation is emitted directly at you, passing through the magnets first. You are wearing a lab coat and goggles. Are you safe? A. No, beta radiation is not deflected by magnets so it would have continued straight and hit you . B. Yes, beta radiation is strongly deflected by magnets so it would have missed you. C. Yes, beta radiation is easily blocked by the lab coat. D. No, it was beta radiation and very dangerous.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
