Can a scientific theory become a law? For full credit you'll need to answer this question correctly and provide an explanation to support your reasoning.
a molal concentration of 6.25 m has a density of 1.300 g/mL. What is the molar concentration of this solution?
Compute the amount of heat required to boil 92.1 grams of benzene (C6H6), start from a temperature of 42.5 degrees Celsius.
While 111g of 2-methyl-2-propanol was heated with phosphoric acid, a colorless gas evolved. This gas was passed through a CCl4 solution containing 0.16 g Br2 per mL solution. Exactly 1.0 L ofthe solution was discolored by the gas generated in ther..
If 26mL of 5.2M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid? 2NaHCO3+H2SO4=Na2SO4+2H2O+2CO2
An element X reacts with oxygen to form XO2 and with chlorine to form XCl4. XO2 is a white solid that melts at high temperatures (above 1000 ? ). Under usual conditions, XCl4 is a colorless liquid with a boiling point of 58.?. XCl4 reacts with wat..
