Given Heisenbergs uncertainty principle, how can it be that it is so important for quantum mechanics, but not much of a concern for our every day actions
Calculate the % of acetic acid in vinegar is the mass of acetic acid is 0.104 g and the mass of the vinegar is 2.00 mL, assuming that the density of vinegar is 1.02 g/mL.
Calculate the heat released when 1.95 L of Cl2(g) with a density of 1.88 g/L reacts with an excess of sodium metal at 25°C and 1 atm to form sodium chloride.
What is the total sample size (in grams) for a sample of disulfur octoxide which contains 3.29 g of oxygen
How is concentration an intensive property? I mean if you add more amount of a substance(mass), the number of moles increase and so the concentration increases.
Calculate the pressure when the volume is 1.27 L and the temperature is 3.00 × 102 K.
