What is the molality of particles in a solution containing 25.4 g of Al(NO3)3 dissolved in 530. g of water? Use molar masses with at least as many significant figures as the data given.
Molarity is only one of many ways to express concentration. Another is percent mass per volume or %(m/v). For example, vinegar usually contains about 5 %(m/v) acetic acid(5g acetic acid/100 mL vinegar)
Upon reaction with excess sulfamic acid, HSO3NH2, a 0.121g sample of a mixture of sodium nitrite, NaNO2, and sodium chloride, NaCl, produced 28.3 mL of nitrogen gas collected over water at 25.3 degrees Celsius and at a barometric pressure of 738 m..
How much heat is absorbed in the complete reaction of 3.00 grams of SiO2 with excess carbon in the reaction below? Change in H degrees for the reaction is +624.6 kJ. SiO2 (g) + 3C (s) -> SiC (s) + 2CO (g)
An equilibrium mixture of NO(g), O2(g) and NO2(g) is allowed to expand from 1.0 to 2.0 L at a constant temperature. Given that 2 NO(g) + O2(g) 2 NO2(g) which of the following statements is correct
What are the spectator ions in the solution after the complete neutralization reaction occurs when mixing the weak acid H2CO3 (aq) and the strong base NaOH (aq)?
Dinitrogen tetraoxide, N2O4, decomposes to nitrogen dioxide in a first-order process. If k=2.5 x 10 to the 3rd s-1 at -5degrees C and k=3.5 x 10 to the 4th s-1 at 25 degrees C, what is the activation energy for the decomposition?
Set up the problem by listing the reactions unknowns equations and knowns b.) Calculate the concentrations of all chemical species present in the solution, and the pH.
a sample of neon is collected at 2.7 atm and 12.0 degrees celcius. if has a volume of 2.25 l. what would be the volume
The hydrogen is recovered as its most stable oxide. When the oxide was made to decompose completely it released 1.274x10^25 molecules of oxygen gas.
In a particular titration experiment a 25.0 mL sample of an unknown monoprotic acid required 30.0 mL of .200 M NaOH for the end point to be reached. What is the concentration of the acid?
The dipole moment (h-BR) of (a polar covalent molecule) is 0.82 (debye), and its percent ionic character is 12.1. Estimate the bond length of the bond in picometers.
A mixture of four gases exerts a total pressure of 860 mm Hg. Gases A and B each exert 220 mm Hg. Gas C exerts 110 mm Hg. What pressure is exerted by gas D?
