Answer:
I think the answer is C because I know
Answer:
D results are based on an undisclosed process or procedure
Explanation:
Periodic trends , arising due to the arrangement of the different elements in a periodic table. It includes electronegativity, ionization energy,electron affinity, atomic radius, metallic character and chemical reactivity.
With the help of the periodic trends,we can predict or determine an element's properties.
Answer: Both heat and energy.
Explanation:
Answer: C. a compound in which one or more carbon atoms have double or triple bonds.
Explanation:
Saturated hydrocarbons are defined as the hydrocarbons in which single bond is present between C-C atoms. The general formula used for these hydrocarbons is . Example:
Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent bonds present between carbon and carbon atoms. They are known as alkenes and alkynes respectively. The general formula used for these hydrocarbons is and respectively. Example:
Both the hydrocarbons are not soluble in water as they are non polar in nature unlike water which is polar.
Cycloalkanes are also saturated hydrocarbons as single bond is present between C-C atoms.
Thus the correct statement is An unsaturated hydrocarbon is a compound in which one or more carbon atoms have double or triple bonds.
