Hello!
Oils that remain a clear color in the refrigerator are unsaturated.
Unsaturated fats are those with double bonds in their fatty acid chain. These are known as being "healthier" than the saturated fats, which don't have any double bonds. Unsaturated fats, when put into the refrigerator are harder to become solid and change color than saturated fats because the double bonds make the structure to have less intermolecular interactions by steric hindrance and thus a lower melting point.
Have a nice day!
Answer:
Homologous series is defined as a systematic order of structurally similar organic compound containing same functional group in their family and two adjacent members differ in their molecular formula by -CH2 unit.
Characteristics:
1.Various members of homologous series contain same functional group.
2.Various members of homologous series can be represented by common formula.
3. All members of a homologous series have almost similar chemical properties.
4. All members have common method of preparation.
5.Two successive members of homologous series have different chain length or difference in their molecular formula by -CH2 unit.
6.The members of homologous series show different physical properties.
Answer: B
Explanation: since the balloon is getting bigger it would make sense for the volume to increase ( get bigger) when volume increases the pressure decreases
<span>Each mole contains Avagodro's number of atoms i.e. 6.023x10^23, so
3 moles x 6.023x10^23 atoms/mole = 18.069x10^23 atoms = 1.8x19^24 atoms </span>
