How many grams of solid barium sulfate form when 18.6 mL of 0.160 M barium chloride reacts with 65.1 mL of 0.055 M sodium sulfate? Aqueous sodium chloride is the other product.
What mass of methane, CH4, is contained in a 500.-mL sample of CH4 at STP?
How do you tell whether a solution is basic, acidic or neutral just by looking at the formula? Like KCl. I need to know how to figure out whether it's neutral, basic or acidic and have no clue how this is done.
Predict whether each of the following molecules is polar or nonpolar: (a) CCl4 (b)NH3 (C)SF4 (d) XeF4 (e) CH3Br (f) GaH3
What is the possible chemical explanation for this? I understand that a reaction using a thiamine catalyst at room temperature for 48 hours may lead to lower yield due to catalyst decomposition, but I'd like to know a more technical explanation.
Determine the work done by the evolution of H 2 in the subsequent reaction on the surrounding atmosphere with1atm pressure and at 25 degree celsius temperature and express your answer in Joule
a) what is the ratio of conjugate base to conjugate acid after 100 ml of 1M HA is adjusted to a pH of 8? b) under the conditions in part a, how many moles of HA are present? How many moles of A- are present? c) What is the pH of the solution descr..
The mass of 158 mL of the gas, measured at 556 mmHg and 310 K is found to be 0.275 g. What is the molecular formula of the compond?
Suppose the pH of the water is 4.67 and that the concentration of iron(II) in the water is 5.17x 10-5 M, what is the potential of the corrosion reaction under the above conditions at 298 K?
Express b in terms of the mass m of each atom and the temperature T of the gas( and other constants), given that the Boltsmann factor in P(cx) pertains to the x- component of the kinetic energy of each atom in the gas.
What volume of 2.94 M HNO3 can be made by diluting 128 mL of concentrated nitric acid (16.0 M HNO3)
Determine the value for delta H solution at infinite dilution calculated from the following delta standard H of formation
To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. A chemical engineer places a mixture of noble gases consisting
