Calculate the product of 3.214 x 10-6 and 2.6x10-3. Answer using the correct number of significant figures.
What is the value of 3.214 x 10-6 divided by 2.6x 10-3. Give the answer to the correct number of significant figures.
Calculate the number of grams of alcohol present in 1.00 L of 78 proof gin. The density of ethanol is 0.798 g/mL.
If a sample containing 3.00 mL of nitroglycerine (density = 1.592 g/mL) is detonated, how many total moles of gas are produced?
The nuclide As-76 has a half-life of 26.0 hours. If a sample of As-76 weighs 344 g, what mass of As-76 remains after 538 minutes.
Which of the following is a neutralization reaction?
what is the pH of the resulting solution ? (Assume that the volume change does not change upon adding hydroiodic acid) Hypochlorous acid HClO Ka1=3.5x10-8
Hydrogen gas was cooled from 150C to 50 C. It's new volume is75 mL. What was it's original volume?
the carbacation to produce 2,4,4-trimethyl-2-pentene and 2,4,4-trimethyl-1-pentene. in order to calculate the % yield, could you help with the correct balanced equation for this reaction, as i would need the moles ratio?
A reaction vessel at 27 degrees C containsa mixture of SO2 (P = 3.10 atm) and 02 (P=1.10 atm). When a catalyst is added to the reaction 2SO^2(g) + O2 (g) = 2SO3 (g) takes place
To a sample of alkaline earth metal carbonate (MCO3; 0.250 g) was added 30.0 mL HCl (0.250 mL). Carbon dioxide gas evolved out from the solution. After the reaction was completed.
Calculate the weight percent composition of the mixture, using the same assumptions as in part A.
The US consumed 18.8 million barrels (Mbbl) of crude oil per day in 2009. The BP Gulf Oil Spill totaled roughly 200 million gallons of crude oil.
