Consider the following reaction at 298K.
2 Cr" (aq) + 3 H2 (g) → 2 Cr (s) + 6 H* (aq)
Which of the following statements are correct?
Choose all that apply
The reaction is reactant-favored.
AG°<0
On=6 mol electrons
K>1
Eºcell < 0

the correct answer is:

a. formation of precipitation

the answer is a for sure mark brainliest i had got this right on usatestprep

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.
