The activity series shows that solid chromium will be oxidized to form
A. chromium 3+ ion
B. chromate ion
C. nothing
D. chrome

A. chromium 3+ ion

Explanation:

The activity series shows that chromium will be oxidized to chromium 3+ ions. This series shows the reactivity of each metal relative to one another.

It is used to predict the activity of metals.

                      Cr     ⇄      Cr³⁺     +      3e⁻

     The more oxidized  metals are located at the top of the series.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
