determined that each molecule of the unknown base could accept two protons. What is the molar mass of this unknown compound?
Carbon is a fascinating element that is capable of forming four covalent bonds.
one day you notice that the outside temperature increase by 16 degrees Fahrenheit between your early morning jog and your lunch at noon. what is the corresponding change in temperature in the Celsius and Kelvin scales?
A sample of He gas (V = 3.0 L) at 5.6 atm and 25 °C was combined with 4.5 L of Ne gas at 3.6 atm and 25 °C in a 9.0 L flask (which was initially evacuated).
2.00 L of H2 at a pressure of 368 torr and 1.00 L of N2 at an unknown pressure. If the total pressure in the flasks is 336 torr after the stopcock is opened.
Calculate the Total Cell Number, You are given a 500ml culture of Euglena from which a 1 ml sample is taken and put in 49 ml of water. Absorbance was measured on this sample but the reading was off the scale
A 26.0-g sample of ice at -11.0°C is mixed with 123.0 g of water at 90.0°C. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
General Chemistry: Energy, Volume, Mass, Molarity, and Moles, Benzene is an organic solvent with the formula C6H6. It boils at 80.1 degrees celcius and melts at 5.5 degrees Celsius. Benzene's density is 0.88gm/ml; its heat of vaporization is 30.0 ..
Dicarbonyl compounds, such as benzil, can be characterized by reaction with o-phenylenediamine to form a substituted quinoxaline.
Calculate the pH of a solution prepared by dissolving 0.30 g of BaO in enough water to make 0.800 L of solution.
Alkenes and non conjugated dienes usually have absorption maxima below 200nm. Compounds that have conjugated multiple bonds have maxima at wavelengths longer than 200nm.
