Answer: The given statement is true.
Explanation:
Chemical bonds are defined as the bonds formed due to interaction of electrons of two same or different atoms. Basically, these electrons are physically attracted towards each other because of which either sharing or transfer of electrons tend to take place.
For example, Cl has 7 valence electrons and sodium has 1 valence electron. In order to gain stability when both sodium and chlorine will come closer then Cl will attract one electron from sodium leading to the formation of a new compound NaCl.
Thus, we can conclude that the statement chemical bonds are physical attractions between atoms resulting from the interaction of their electrons, is true.
4.25 x 10¹⁴L
Explanation:
It is impossible to convert from km to liters.
km is a unit of distance or length whereas liters a unit of volume, the amount of space a body occupies.
But let us assume you meant km³:
Converting form km³ to liters:
Given 4.25 x 10⁸km³
1000m³ = 1Liter
1000m = 1km
Now, to solve this problem, we are going to use a conversion factor of 1 to multiply our unit.
km³ = km x km x km
4.25 x 10⁸ x km x km x km x
x
= 4.25 x 10¹⁴L

The conversion factor from compound to element is actually
just based on the number of elements in the compound itself.
From the compound C12H22O11, we can say that there are 12
C, 22 H and 11 O, therefore the conversion factors are:
1 mol C12H22O11=12
moles of C
1 mol C12H22O11=22
moles of H
1 mol C12H22O11= 11 moles of O
