If the refrigerator has no room to cool the meat that you've just cooked, then you should clear it with other stuff or food that has not been consumed for days. There might be some goods that are not good for consumption anymore even though it has been placed in the ref for a couple of days. Hope this answers your question.
Question 5 is the second one.
The compound
will have a triple bond.
Explanation:
A compound which consists of carbon and hydrogen atoms is known as a hydrocarbon.
Alkanes, alkenes and alkynes are all hydrocarbons.
- General chemical formula of an alkane is
. In an alkane molecule, all the atoms will be bonded through single bonds.
For example,
is propane.
- General chemical formula of an alkene is
. An alkene molecule will have atleast one double bond between two carbon atoms.
For example,
is ethene.
- General chemical formula of an alkyne is
. An alkyne will have atleast one triple bond between two carbon atoms.
For example,
is propyne.
Thus, we can conclude that out of the given options
will have a triple bond.
Answer:
C. Tip had the lower pressure, it was 652.71mmHg
Explanation:
To answer this question you need to convert both values into a common unit so you can compare directly.
87kPa = 652.71 mmHg
The two oxygen atoms share two pairs of electrons, so two covalent bonds hold the oxygen molecule together
