What is the density if carbon dioxide gas at -25.2° C and 98.0 kPa
An automobile gasoline tank holds 22kg of gasoline. When the gasoline burns, 85kg of oxygen is consumed & carbon dioxide & water are produced? What is the total combined mass of carbon dioxide & water that is produced?
What fraction of the total residues are branch points? B) How many reducing ends does this amylopectin have?
An amount of lactic acid is dissolved in water and the reaction is allowed to reach equilibrium. The concentration of the protonated acid is found to be 2.5 M.
If the volume of 0.200 M NaOH needed to neutralize 0.410 g of an unknown acid is 35.0 mL, what is the molar mass of the monoprotic acid
Exactly 18.9 mL of water at 26.0 C are added to a hot iron skillet. All of the water is converted into steam at 100C. The mass of the iron skillet is 1.35kg and the molar heat capacity of iron is 25.19 J/mol C. What is the temperature change of th..
