Calculate the formula mass for the compound nitrous acid.
kari74 [83]

Answer:

47.01g/mol

Explanation:

The formula of Nitrous acid is HNO₂:

The formula mass of a compound gives the sum of the atomic masses of the elements that makes up a compound.

Atomic mass of H = 1.0079g/mol

                          N = 14.0067g/mol

                          O = 15.9994g/mol

Formula mass of HNO₂ = 1.0079 +  14.0067 + 2(15.9994)

                                        = 1.0079 +  14.0067 +31.9988

                                         = 47.01g/mol

What is the oxidation number for zinc? How does zinc's electron configuration account for this oxidation number?
IRINA_888 [86]
+2 is the oxidation number for Zinc
<span>Oxidation Number for a Transition metal = Number of Unpaired d-electrons + Two s-electrons  
</span>[Ar]4s2 3d10 is the electron configuration for zinc. The d-block is full with 10 electrons meaning there are no unpaired d-electrons, so the oxidation number is 0 unpaired d-electrons + 2 s-electrons = +2

Answer:

1= Magnesium

2 = Option 3 =  1s² 2s² 2p⁶

Explanation:

An electrically neutral atom consist of equal number of protons and electrons.

The answer for 1st q is magnesium because the electronic configuration showed twelve number of electrons. The atomic number of magnesium is twelve that's why this configuration is of Mg.

Mg₁₂ =  1s² 2s² 2p⁶ 3s²

The second answer is option three because has atomic number ten and third electronic configuration have ten electrons.

Ne₁₀ = 1s² 2s² 2p⁶

It is stable electronic configuration. Neon is inert because of this electronic configuration. The outer most shell is completely filled.
