Use a periodic table. Count the exponent for your atomic number. So, 1s2 2s2 2p5= Fluorine
1s2 2s2 2p6 3s2 3p5= Chlorine
1s2 2s2 2p6 3s2 3p6 4s2 3d6= Iron

Aleonysh [2.5K]

Answer:

CuSO4 cell will have the greatest amount of deposit among all three. The deposit will occur at the cathode

Explanation:

The valence of the elements in this case is as follows -

Cu - 2e-

Sn - 4e-

Cr - 3e-

CuSO4 cell will have the greatest amount of deposit among all three

The atoms of copper metal will deposit at the cathode. At the cathode, the least number of moles of electrons needed .

Hence, more amount of copper  can be extracted out by the electrolyte

How many oxygen atoms are in 2(NO3)
torisob [31]

6 Oxygen atoms

Explanation:

In the molecule 2(NO₃):

An atom is the smallest indivisible particle of any substance. They chemically combine to give compounds and molecules. Some of them are able to exist on their own.

An element is a substance that has a unique atom.

      NO₃ has two elements: N   and O

      Number of atoms:

    N = 1

    O = 3

but we have two moles of NO₃

 O = 3 x 2 = 6

 N = 1 x 2 = 2

Which of the following pairs does not share the same empirical formula? C2H6 and C6H18 C3H6O3 and C2H4O2 C3H6 and CH4 CH2O and C
denpristay [2]
C3H6 and CH4

The empirical number is found by looking at the ratio of the numbers. For example, H20 and H402 have the same empirical formula because the ratio remained similar. 2 H to 1 O.
