Which metal does not form cations of differing charges? ( Which metal is NOT a transition metal?)A) Na

B) Cu

C) Co

D) Fe

E) Sn

Answers

Answer 1

Answer:

The metal that does not form cations of differing charges is Sodium (Na).

The transition metals refers to the group of metals which one can find in the middle of a periodic table. Some of the metals that are able to form cations with different charges include:

Chronium (Cr)

Iron (Fe)

Cobalt (Co)

Copper (Cu)

Tin (Sn) ,

Mercury (Hg)

Lead (Pb)

It should be noted that Sodium (Na) is a metal metal that does not form cations of differing charges.

Therefore, the correct option is A.

The heat of vaporization for ethanol is 0.826 kJ/j. Calculate the heat energy in joules required to boil 45.65g of ethanol

Answers

Answer:

ethanol is already at the ethanol's boiling point: (0.826 kJ/g) x (70.05 g) = 57.8613 kJ = 5.79 x 10^4 J.

Missing: 45.65 ‎| ‎Must include: ‎45.65

Explanation:

Answer:

Explanation:

Supposing the temperature of the ethanol is already at the ethanol's boiling point:

(0.826 kJ/g) x (70.05 g) = 57.8613 kJ = 5.79 x 10^4 J
