A bicycle tire is filled with air to a pressure of 85.0 psi at a temperature of 19°C. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58°C. The volume of the tire increases by 2.8%. What is the new pressure in the bicycle tire?
How many milliliters of 0.0120 M Na2S2O3 solution are needed to dissolve 0.740 g of AgBr.
A 56.0 mL solution of phosphoric acid is neutralized by 136.0 mL of 2.6 M NaOH. What is the concentration of the acid?
Calculate the approximate SO 2 mass emission in lb/day.
when a metal was exposed to light at a frequency of 4.63*10^15 Hz, electrons were emitted with a kinetic energy of 3.10*10^-19 J.
Calculate the number of grams of KClO3 needed to make 400 mL of 0.913 M solution.
The mass spectrum of an organic compound shows the relative abundances of M to be 85.12% and M+1 to be 0.9206%. Assuming the peaks are caused by C-12 and C-13 isotopes
Draw a mechanism for each reaction which explains the results. All electron movement must be indicated by arrows.
Suppose 5.00g of Ca is added to 50.0mL of 1.00M HCL. Determine the limiting reactant in this case and number of moles of calcium actually consumed.
Find out how many total moles of gas are produced If a sample has 2.10 mL of nitroglycerine (density = 1.592 g/mL) is detonated?
What is the value of x in the formula for the hydrate? (hint: remember that x represents the ratio of moles of H2O to moles of hydrate compound, and that moles of hydrate compound equals the moles of anhydrous compound)
carboxylic acids react with alcohols to form esters which are found in all plants and animals. what is the percent by mass of carbon in each of the following esters?
Geometric isomers illustration, This is more of a theoretical question I think. Co(NH3)5ClBr has two compounds for that one formula.
