When concentrated sulfuric acid (18.0 M) is added to sodium chloride, hydrogen chloride gas is formed.
H2SO4(l) + NaCl(s) ? NaHSO4(s) + HCl(g)
When 50.0 mL of concentrated sulfuric acid is added to 1.15 g of sodium chloride, what volume (in mL) of hydrogen chloride gas is obtained at 1.00 atm pressure and 25oC?
A molecule can be polar or nonpolar depending upon the nature of the bonds and the shape of the molecule. For a molecule that has different outer atoms the molecular symmetry will decide the polarity.
a sample of sodium reacts complete with 0.497kg of chlorine, forming 819g sodium chloride. what mass of sodium reacted?
The flask was then shaken until the solution was uniform. A 45.0- sample of this glucose solution was diluted to 0.500 . How many grams of glucose are in 100. of the final solution?
What is the procedure for the extractions (to MAXIMIZE THE YIELD) and volumes? (i.e. How much water, NaCl, sodium bicarbonate and in what order)?
Many fish which normally line in mountain streams (where the water temperature is 0 degrees celcius) die when water in which they live warms up to 25 degrees C. How many oxygen molecules are there in 1.0 ml of water at these two temperatures?
A 3.00-liter sample of gas is at 417 Kelvin and 0.65 atmosphere. If the volume is decreased to 1.50 liters and the pressure of the gas is increased to 1.95 atmospheres, what will be the temperature of the sample?
