What would the mass of 1 Liter (1000 mL or 1000 cm3) of your element be? With equations (my element is calcium)
Calculate the standard reduction potential for the reaction for the reaction Cu(III) to Cu(II).
Identify HClO2 as an acid, base, or salt. Please explain methodology.
What is the molar solubility of the insoluble sulfate salt of tungsten(VI) in a 0.99 M Na2SO4 solution, if the Ksp value is 7.57×10-14. Recall that the molar solubility is the moles of salt per liter of solution.
Calculate the pressure of 1.00 mole of CH4 in a 1.00 L container at 300.0 K using first the vand der Waals equation
Explain how the calculated formula of the hydrate would be changed if water from the air is absorbed by the hot dry sample as it cools.
phosphenolpryuvate how many moles of ATP can be derived just from reduced electron carriers (not substrate-level phosporylation?
Ascorbic acid, HC6H7O3, also known as vitamin C, is a weak acid. It is an essential vitamin and an antioxidant. A solution of ascorbic acid is prepared by dissolving 2.00 grams in enough water to make 100.0 mL of solution
Calculate the pH of 100. mL of 0.28 M NH3 before and after the addition of 4.5 g of NH4NO3, and account for the change. Assume that the volume remains constant. What is the pH before and after the addition of NH4NO3
Explain how many milliliters of water vapor, measured at 318 degrees C and 735torr, are formed when 33.6mL of NH3 at 825torr and 127 degrees C react with oxygen according to the following equation. 4 NH3 + 2 O2 ---> 2 N2 + 6 H2O
What role do the potassium chloride (KCl) and potassium sulfate (K2SO4) play in this experiment
What is the volume of the bubble (in cubic centimeters) just before it reaches the surface? (The density of water is 1000 kg/m^3 and air pressure is 1E+05 N/m^2.)
First lab experiment - zinc and copper aqueous solutions were tested in a microscale cell well where the voltage reading was 1.04V. Solutions were each at about 5mL.
