Answer:
No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.
Explanation:
from the shape of methane which is tetrahedral it's evident there's no hydrogen bond only C-H bond.
Reaction:
Magnesium is a stronger reducing agent than copper and is thus able to reduce copper(II) oxide.
Products of the reaction: Magnesium oxide and metallic copper.
Answer: The size of actual bed is 75 inches
Explanation: Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.
Scale= original dimension/miniaturised dimension
Given that scale is 1:25
It means that every 1 inch on paper would correspond to 25 inches in reality.
The length of the model bed= 3 inches
Hence, the length of the original bed is 25*3 = 75 inches
