There are two possible ways to connect the atoms in hydrogen cyanide: HCN and HNC. Write the Lewis structures and use formal charges to predict which is the more likely structural arrangement.
When 284.5 g of ethylene (C2H4) burns in oxygen to give carbon dioxide and water, how many grams of CO2 are formed?
The mass of the ice cube is 14.6 g, and its initial temperature is -13.1 °C. The water resulting from the melted ice reaches the temperature of your skin, 30.7 °C. How much heat is absorbed by the ice cube and resulting water

what is the weight of O in 742.0 g of citronella oil that has the chemical formula C10H18O
Calculate the specific rotation of the compound. A sample of 150 mg of an organic compound is dissolved in 7.5 ml of water. The solution is paced in a 20-cm polarimeter tube and the rotation measured in a polarimeter
The following five beakers, each containing a solution of sodium chloride (rm NaCl, also known as table salt), were found on a lab shelf:
Draw the product of the following reaction between a ketone and an alcohol. H3C--CO--CH3 + HO--CH2--CH3 ---H+--> how would you classify the product of the reaction? -alcohol -ketone -hemiacetal -acetal
Ethylene is supplied by a 60.9-L gas cylinder initially at 2200.0 psig and 25.0°C. Once leaving the cylinder, a regulator reduces the pressure to 15.0 psig, and a valve allows 1.000 mL/s of ethylene at 25.0°C to flow into the reactor
