Which group will have a charge of +2 when ionized? O A. Alkali Earth metals
OB. Halogens
C. Alkali metals
D. Noble gases

Alkaline earth metals

Explanation:

Group 2 has 2 valence electrons that they lose when being ionized, thus making  their charge 2+.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
