Answer:
object b by 0.42g/cm cubic
Explanation:
density = mass/volume
object a =10/8
=1.25g/cm^3
object b = 10/6
=1.67g/cm^3
therefore object b has greater density and by 0.42g/cm^3 (1.67- 1.25)
3) electronegativity difference
Explanation:
The degree of polarity of a bond is indicated by the electronegativity difference between the atoms that forms the bond.
Electronegativity is the of atoms in a bond to attract the valence electrons in chemical bond more closely to themselves.
- An atom with a high electronegative value often pulls the electron to itself more.
- If the elecronegativity difference between the two species is between 0.4 and 1.7, they are polar covalent bonds.
- If is is greater than 1.7, they are ionic bonds.
- If less than 0.4, then a non-polar covalent bond must have formed.

Hydrocarbons are chains of C and H. C and H are held together by covalent bonds.
hydrocarbons are of three main types
alkanes - only single bonds between C atoms
alkenes - double bonds between C atoms present
alkynes - triples bonds between C atoms present
saturated hydrocarbons definition is when there are only single bonds present
from the given compounds
propane - only single bonds
propene - double bond
propyne - triple bond
propanal - double bond between C and O
only compound with single bonds is propane
answer is propane
Answer:
reducing agent
Explanation:
A reactant that loses electrons and is oxidized is the reducing agent because it provides electrons to the reactant that gets reduced.
