Answer:
The empirical formula is C₂H₃
Explanation:
The empirical formula of a chemical compound is defined as the simplest positive integer ratio of atoms present in a compound.
The reaction of combustion for a CₐHₓ is:
CₐHₓ + (a+x/4) O₂ → a CO₂ + ˣ/₂ H₂O
The moles obtained are
15,3 g of CO₂ ×
= 0,3476 moles of CO₂≡moles of C
4,70 g of H₂O ×
= 0,2608 moles of H₂O × 2 = 0,5216 moles of H.
The ratio H:C is 0,5216/0,3476= 1,5. That means you have 1,5 H per 1C, that is the same than 3H per 2C. Thus, empirical formula is:
C₂H₃

=>. the function of greenhouse gases are
=>. it captures the heat comming out from the
sun
=>. by capturing the heat it makes our earth
warm
=> if excess of heat will traped by them then
our earth become more warm and this leads
to increase in temperature
=> when the overall temperature will increase
then the ice sheets on pole will melts
and this leads to increase in sea level
=> then the land near water will sinks in water
Answer:
All hydrogens are in same environment. Hence it will not split which shows as singlet for 4 hydrogen
