Ghow many electrons are transferred in the following reaction? ( note that the reaction below needs to be balanced! ) mg (s) + cr3+ (aq) → cr (s) + mg2+ (aq) how many electrons are transferred in the following reaction? ( note that the reaction below needs to be balanced! ) (s) + 3+ (aq) → (s) + 2+ (aq) 4 1 2 3 6

6

Explanation:

Mg (s) + Cr3+ (aq) → Cr (s) + Mg2+ (aq)

Balancing the equation above we have,

3Mg (s) + 2Cr3+ (aq) → 2Cr (s) + 3Mg2+ (aq)

Half reaction

3Mg (s) → 3Mg2+ (aq) +6e-

2Cr3+ (aq) + 6e- → 2Cr (s)

Therefore six electrons were transferred (6e-)

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
