A solid will start to melt when it reaches its melting point. For example the melting point of Helium is -272° Celsius and the melting point of Carbon is 3500° Celsius . Helium has the lowest melting point and carbon has the highest melting point in the periodic table.
Answer:
a. Alkynes (CnH2n+2) are saturated hydrocarbons.
I can’t do math right now but the formula is density = mass / volume
Answer:
Option a
Explanation:
Ester ethyl butanoate is a Chemical compound with Molar mass of 116.16 g/mol, the Boiling point is 121 °C and the Density is 879 kg/m³.
Looking at the chemical representation of the compound, it can be shown that the chemical compound contains the an ester functional group and this it is formed through the reaction of a -COOH containing compound/salt and an alcohol.
The chemical representations showing the chemical reaction is given below;
CH3CH2CH2COOCH2CH3 + Acid(H2O, H^+) =========> C2H5OH + C4H8O2.
Thus, acidic hydrolysis of the ester gives ethyl alcohol and butanoic acid.
