Analysis of water in a sediment sample at equilibrium at ph 7.00 showed [so42-] = 2.00 x 10^-5 m and a partial pressure of h2s of 0.100 atm. show with appropriate calculations if methane, ch4, would be expected in the sediment.
How many grams of sucralose would you need for a solution that has the same sweetness as one made with 2.00g of sugar? Please show how to solve problem
Diamond has a face-centered cubic unit cell, with four more C atoms in tetrahedral holes within the cell. Densities of diamonds vary from 3.01 g/cm3 to 3.52 g/cm3 because C atoms are missing from some holes.
Lithium iodide has a lattice energy of and a heat of hydration of. Determine how much heat is evolved or absorbed when 40.0 of lithium iodide completely dissolves in water.
What are some ways to induce recrystallization (Name 3), if your solute refuses to recrystallize after performing the required 7 steps?
the freezing point of the resulting solution is 3.77*C. The freezing point of pure benzine is 5.48*C. Calculate the molar mass of the compound.
In the unbalanced reaction, Sn + HNO3 ---> Sn(NO3)2 + H2), 2.100 grams of Sn(NO3)2 was formed. How many grams of NO were formed and how many moles of HNO3 were reacted? (HINT: the coefficient of Sn is 3).
The high-field:low-field integration ration is 2:1. Deduce the structure of the organic hald and explain the NMR signals. I'm thinking it's 1,1-dichloropropane.
The specific rotation of the pure R-enantiomer of a compund is +80 degrees. What is the composition of R- and S-enantiomers in a mixture
What volume (in mL) of an 8% w/v acetic acid solution would be needed to form 2.2 L of carbon dioxide gas at 25.2 degrees Celsius and 0.9982 atm? Assume the acid is reacted with excess sodium bicarbonate, and round your final answer to two sig fig..
Using butane as your only carbon source, please propose a synthesis to make trans-2-ethyl-3-(1-oxoethyl)oxirane. any common reagent
A total of 2.00mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 188g of solution. The reaction caused the temperature of the solution to rise from 21.0 to 24.7 degrees Celsius .
