You should clean up after every investigation because if you leave a mess, maybe another detective will come in and get lost because of the mess you left.
Answer is: C₄H₈.
C₄H₈ is hydrocarbon, organic compound<span> consisting only of carbon and hydrogen.
CaH</span>₂ (calcium hydride) is alkaline earth hydride, inorganic compound.
H₂O₂(hydrogen peroxide) is pale blue, clear, inorganic <span>liquid.
P</span>₂O₅ (phosphorus pentoxide) is <span>white, crystalline solid inorganic compound.</span>
The answer to this question would be True.
Answer : Option C) The polar bonds are oriented in opposite direction.
Explanation : A molecule of carbon dioxide 
contains two polar covalent bonds. This molecule is non-polar because the polar bonds are oriented in the opposite direction.
In order to be a polar molecule, carbon dioxide must have both a slightly negative side and a slightly positive side in its molecule. The orientation of the lone pairs of electrons present on each oxygen atom cancels each other, making the molecule non polar.
