Calculate the maximum mass of calcium metal that should be used in this experiment with a 50mL eudiometer tube for gas collection. Assume that the hydrogen generated occupies 45 mL at STP. The experiment is: reaction of .054 g of Al with 100 mL of 6.00 M sulfuric acid.
each successive hydrogen is more easily substituted until the trihalo species is obtained. Explain
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.
Calculate the cell potential for the following reaction as written at 69 °C, given that [Mg2 ] = 0.876 M and [Fe2 ] = 0.0160 M. Standard reduction potentials can be found here.
the initial pH value was2.5. You found that pH=pKa=4.2 when 12.50 mL of NaOH hadbeen added. The concentration of the sodium hydroxide was 0.500M. Calculate the molar mass of the acid
A situation with an industrial input of arsenic directly into the lake at 10kg/Day. The lake volume is 1.2 x 10^8 m^3, and the average depth is 10m.
Predict what will happen and check your predictions. Change the styling so that instead of the color changing the link becomes bold when you hover over it. (You need to use the font-weight property.) Why does the white background extend to the end..
We wish to prepare a buffer of pH 10 using common laboratory reagents. How many mL of 6M HCl would we have to add to a solution prepared by adding 100 mL of 15M NH3 to 200 mL of water?
Give the formula of a compound that contains a secondary hydrogen and Give the formula of a compound that is a secondary alcohol
What volume of CO2 would be produced each day? Suppose the gas mixture produced by the decomposition is trapped in a container at 17 degree celcius
If it requires 5,650 Joules of potential energy to lift a mass 15 ft into the air, what is that mass in units of kg
When much of the ATP is depleted in a cell, a considerable amount of cAMP is formed asa product of ATP degradation. This cAMP activates an enzyme phosphorylase that splitsglycogen
an electron is confined to a linear region with a length of the same orderas the diameter of an atom (about 100 pm)
