Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio

This is false. This is not a benefit of digital technology.
<h3>What is digital technology?</h3>
This is the term that is used to refer to all of the hard wares and the soft ware components of the computer as well as the networks and internet. It also involves communication technology and information, that is used on the computer.
The benefits of digital technology has to do with the fact that devices are created to be more compact, efficient and are able to run in a much faster way. Modern digital technology has created a system where devices are portable as well as handy.
Hence we can say that It is false that a benefit of digital technology, such as desktop publishing, is the restriction of design work to trained designers thereby elevating the standards of graphic design.

Answer:
If a mother is smoking and there are significant birth weights, a bar graph will be most effective. A bar graph can show how many children have similar weights, and you can tell which weights are most common.
Hope this helped.
