Answer:
The purpose of a filter paper inside a beaker is to retain the suspended solid particles found in the solution.
<em>The retention capacity of the filter paper will depend on the size of the pores of the filter</em>. Thus, for example, if the pores of the filter have a diameter of 1 mm, particles with a diameter greater than 1 mm will be retained, and the rest of the solution will pass through the pores.
The removal of impurities through filters is a physical separation process.
Answer:
The percentage of N in the compound is 0.5088
Explanation:
Mass of compound = 8.75 mg = 8.75×1000 = 8750 g
Mass of N2 = number of moles of N2 × MW of N2 = 1.59 × 28 = 44.52 g
% of N in the compound = (mass of N2/mass of compound) × 100 = (44.52/8750) × 100 = 5.088×10^-3 × 100 = 0.5088
They have high melting and boiling points and are hard and brittle
