[8] Potassium ion, K', is present in most foods and is an essential nutrient in the human body. Potassium-40, however, which has a natural abundance of 0.0117%, is radioactive with t12 = 1.28x10 years. a) What is the decay constant of 4K? b) How many “Kions are present in 2.50 g of KCI? c) How many disintegrations/s does 2.50 g of KCl undergo? - 19] How many grams of hydrazine, NH., can be prepared from its elements in the reaction: N2(g) + 2H2(g) → N2H(9) when 29.5 g of nitrogen and 50.0 7 of hydrogen gas react at 25°C and 1.00 atm?
