Lithium and nitrogen have the same electron energy levels, actually 2 levels.
Answer:
107Ag has abundance of 51.7%
109Ag has abundance of 48.3%
Explanation: Please see attachment for explanation
Answer:
- At the negative electrode: Mg(s) => Mg2+ + 2e-
- At the positive electrode:Cl- + 2e- => Cl2(g)
Explanation:
1. Magnesium is formed at the negative electrode.
2. Chlorine gas is released at the positive electrode.
Answer:
It conducts electricity
It conducts heat
Water is needed for rusting
Explanation:
Metals refer to elements that are found towards the left hand side of the periodic table of elements. They are found in groups 1- 13 and few of them are also found at the bottom of groups 14 and 15.
Now these metal have certain properties that are general to all of them. two of these properties listed among the options in the question are;
i) They conduct electricity
ii) They conduct heat
These properties apply to all metals universally.
Rusting is an electrochemical reaction in which hydrated iron III oxide is formed. In the electrochemical reaction, water in intimately involved in the process. Hence; oxygen and water are required for rusting to take place.
Kinetic energy is energy that transfers energy by <span>net force which causes it to speed up and that causes more kinetic energy to be added . kinetic energy depends on mass and motion </span><span />
