If a sample solution is 5.00% H2O2 by mass and has a density close to 1.0 g/mL, find the approximate molar concentration of the H2O2 in the solution
Will the yeast cells or the corn seedling have a higher metabolic rate when compared on a mass specific basis (in moles ATP/gram organism x hr)?
Addition of silver nitrate solution results in a precipitate. Assuming that the heat capacity of the solution is the same as pure water, use enthalpies of solution and solubility rules to identify the salt.
Calculate (a) the work done when the gas expands isothermally against a constant external pressure of 200 Torr until its volume has increased by 3.6 dm3, and (b) the work that would be done if the same expansion had occurred reversibly.
A chemical reaction takes place in a container of cross-sectional area 100 cm2. As a result of the reaction, a piston is pushed out through 21 cm against an external pressure of 534 torr.
The solubility of magnesium phosphate at a given temperature is 0.385 g/L. Calculate the Ksp at this temperature.
Which absorption band is more intense; a band due to a single S-O bond or a band due to a single Si-C bond? 2) Compound A (C21H32) decolorizes a solution of bromine in CCl4
According to VSEPR theory, if there are five electron domains in the valence shell of an atom, what will be the expected electron domain geometry.
A thief plans to steal a gold sphere with a radius of 28.8 cm from a museum. If the gold has a density of 19.3 {rm g/cm}^3, what is the mass of the sphere? [The volume of a sphere is V = (4/3)pi r^3.]
Imagine that you have two iron blocks, one with a mass 226 g at a temperature of 46.0 oC, and another with a mass 380 g at a temperature of 134 oC. The two blocks are brought into contact with each other in an insulated container. What is the fina..
Determine the error in the molar mass of Mg(ClO4)2. If 0.982(+/- 0.002)g is dissolved in a 250 mL (+/-0.08 mL) volumetric flask and water added to the mark, what is the concentration and error in the concentration of ClO4-?
The initial temperature of the water was 25.4 C and the final temperature of both the water and metal was 36.6 C. If the specific heat "c"
The lab was where we had to carry out aldol condensation to prepare benzalacetophenones using C7H5OCl and acetophenone. The result was 4-chlorobenzaldehyde
