For the following reaction, 4.41 grams of hydrogen gas are allowed to react with 39.8 grams of iodine .
hydrogen(g) + iodine(s) hydrogen iodide(g)
What is the maximum mass of hydrogen iodide that can be formed? grams
What is the FORMULA for the limiting reagent?
What mass of the excess reagent remains after the reaction is complete? grams
A mixture of Al and Fe weighing 0.2000 g is treated with excess HCI solutions. Each metal reacts separately with the acid, resulting in the production of hydrogen gas H2, and a chloride salt. After treatment, a total volume of 200mL of the evolved gas was collected at 20 °C and 850 torr. Calculate for the mass percentage of Al in the sample.
An animal in hibernation gets the heat their body requires to survive from the biochemical combustion of fatty acids, linoleic acid C18H32O2, is an example of such fatty acid. If air is composed of 78.1% N2, 20.9& O2 and 1% other gases, by volume, calculate for the volume of air in liters needed to burn 1.50kg of linoleic acid at 25°C and 1 atm.
write a chemical equation that represents the complete combustion of a compound that is 34.64% C, 13.86% H, and 51.50% O by mass. How much of the compound is needed to produce 10.1 of the gaseous product as STP
calculate the new freezing point of water when 72.0 g of BaCl2 are added to 0.175 kg of water
How many moles of ethanol is produced if you start with 8.74 g of glucose
The half life of iridium is 12.8 years. Calculate decay constant and average life in minutes
A 3.00 g sample of TNT (trinitrotoluene, C7H5N3O6) is placed
in a bomb calorimeter with a heat capacity of 1.93 kJ/°C; the
ΔHcomb of TNT is −3403.5 kJ/mol. If the initial temperature of
the calorimeter is 19.8°C, what will be the final temperature of
the calorimeter after the combustion reaction (assuming no heat
is lost to the surroundings)
Calculate for the specific heat of 28.0 g of of mercury (Hg)
when 137 J of energy is involved when raised at an initial
temperature of 22.0°C to a final temperature of 57. 0C.
