Answer:
MgO has a highest melting point
C5Br has lowesst
Explanation:
It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. ... Magnesium oxide is made from ions with two charges (Mg 2+ and O 2-) and so has a much higher melting point of 2852°C.
Glucose and galactose (both simple sugars) are produced from the hydrolysis of lactose.

The correct answer is Sulfur Hexafluoride
it’s an inert gas that is known to be six times heavier than the air we breathe. While Helium being lighter makes our voice higher, SF6 makes our voice deeper. The sound travels slower in denser gases which is why our voice will come out deeper and rather slow.
Answer:
has two double C-C bonds
Explanation:
A saturated compound is a compound having the full complement of hydrogen atoms for every carbon atom while an unsaturated compound does not contain the full complement of hydrogen atoms for every atom of carbon.
If we look at C3H4, the only possible structure of the compound is H2C=C=CH2. We can see from this arrangement that the compound contains a cumulative double bond. This is the specific structure that fits into one of the descriptions in the options, the compound contains two double bonds.
