Answer:
The compound may have properties that are very different from those of the elements.
Explanation:
For example - common salt, sodium chloride ( NaCl) has very different properties from sodium and chlorine
Reaction with acid. That is a chemical reaction.
Answer:
d. Pressure
Explanation:
Pressure is not a factor which affect rates of reaction.
However, surface area, temperature, and concentration are factors that affect rates of reaction.
Exothermic is a chemical reaction in which heat is released. Lighting a candle is an example of an exothermic because the flame is the heat being released.
Answer:The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound, C5H10O2, exhibits strong, broad absorption across the 2500-3200 cm^1 region and an intense absorption at 1715 cm'^-1. Relative absorption intensity: (s)=strong, (m)-medium, (w) weak. What functional class(cs) docs the compound belong to List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm^1. The functional class(es) of thla compound is(are) alkane (List only if no other functional class applies.) alkene terminal alkyne internal alkyne arene alcohol ether amine aldehyde or ketone carboxylic acid ester nitr
