Balance the following equation in acidic solution using the lowest possible integers and give the coefficient of water.MnO4-(aq) + H2C2O4(aq) ? Mn2+(aq) + CO2(g)
Suppose that you were to fill a 1L beaker with only 200 mL of water and it is not deep enough to make the water level inside and outside the graduated cylinder the same.
Do you think a comparable spill of a water-insoluble liquid that has a density of 1.20g/mL would have been as harmful to waterfowl and aquatic mammals.
A water pipe fills a container that measures 189 cm , 307 cm ,272 cm in 97 seconds, What is the rate of flow in the pipe in liters per minute.
xygen, contained in a 1.0-L vessel at 4.0atm, is transferred to a 5.0-L vessel containing only Argon, Ar, at 2.0atm. What is the final total pressure in the 5.0-L vessel? Assume that there is no change in temperature, give answer in atm (atmospher..
Hydrogen gas can be prepared by reaction of zinc metal with aqueous HCl. how many liters of H2 would be formed at 770 mm Hg and 16 degrees celcius if 26.5g of zinc was allowed to react
A 4.80 g nugget of pure gold absorbed 298 J of heat. What was the final temperature of the gold if the initial temperature was 24.0°C? The specific heat of gold is 0.129 J/(g·°C).
If 12.5 g of iron(III) oxide (rust) are pro- duced from 8.74 g of iron, how much oxygen gas is needed for this reaction?
Hardness in groundwater is due to the presence of metal ions, primarily Mg2 and Ca2 . Hardness is generally reported as ppm CaCO3 or mmol/L Ca2
