The answer is <span>D.when the aim is to show electron distributions in shells. This is because there are some instances when elements don't possess a regular or normal electron configuration. There are those who have special electron configurations wherein a lower subshell isn't completely filled before occupying a higher subshell. It is best to visualize such cases using the orbital notation.</span>

Consider the balanced equation. 2HCl + Mg MgCl2 + H2 If 40.0 g of HCl react with an excess of magnesium metal, what is the theor
Serga [27]

Answer:

Theoretical yield of hydrogen is 1.11 g

Explanation:

Balanced equation, Mg+2HCl\rightarrow MgCl_{2}+H_{2}

As Mg remain present in excess therefore HCl is the limiting reagent.

According to balanced equation, 2 moles of HCl produce 1 mol of H_{2}.

Molar mass of HCl = 36.46 g/mol

So, 40.0 g of HCl = \frac{40.0}{36.46}moles of HCl = 1.10 moles of HCl

Hence, theoretically, number of moles of H_{2} are produced from 1.10 moles of HCl = (\frac{1}{2}\times 1.10)moles=0.550moles

Molar mass of H_{2} = 2.016 g/mol

So, theoretical yield of H_{2} = (0.550\times 2.016)g=1.11g

How many moles are in 3.4 x 10-7 grams of Silicon dioxide, SiO2?
Varvara68 [4.7K]

Answer:

Number of moles = 0.057 × 10⁻⁷  mol

Explanation:

Given data:

Mass of SiO₂ = 3.4 × 10⁻⁷ g

Number of moles = ?

Solution:

Number of moles = mass/molar mass

Molar mass of SiO₂ = 60 g/mol

by putting values,

Number of moles =  3.4 × 10⁻⁷ g / 60 g/mol

Number of moles = 0.057 × 10⁻⁷  mol

The reaction CO2(g) → C(s) + O2(g) is a decomposition reaction.<br><br> True<br> False
Lyrx [107]

  The reaction CO₂(g)  → C(s) +O₂(g)  is  a decomposition  reaction is true

Explanation

 A Decomposition reaction is a reaction in which involve breaking down  a compound into   two or more  simpler  substances.

 The reaction above is a decomposition reaction since CO₂    molecule is broken down  into C (an  element) and O₂  (a  molecule).
