The measures of two adjacent angles of a parallelogram are in the ratio 3:2. Find the measure of each of the angles of the parallelogram.
Solution: Opposite angles of a parallelogram are always add upto 180°. So, 180°= 3x + 2x Or, 5x = 180° Or, x = 36° So, angles are; 36° x 3 = 108° And 36° x 2...

An organic compound 'X' of molecular formula C2H4O2 gives brisk effervescence with sodium bicarbonate. Give the name and formula of X.
'X' is ethanoic acid (an organic acid). 'X' --> CH3COOH CH3COOH + NaHCO3 -------> CH3COONa + CO2 + H2O Organic acid decomposes sodium bicarbonate and gives brisk effervescence of carbon dioxide gas.
