Number of moles = (0.5 x 100)/1000 = 0.05 moles (1 mark)Molar mass, M, of NaOH = 23 + 16 + 1 = 40 (1 mark)Mass of NaOH needed = moles x M = 0.05 x 40 = 2g (1 mark)correct answer alone scores 3 markscorrec...

Chlorine has fewer shells than iodine - chlorine has 2 and iodine has 4. We know this by referring to the periodic table. This means its outer electrons are closer to the nucleus.Because ...

The breakdown of any product using water is called a hydrolysis reaction.
