Q1. A sample of nitrogen gas at a pressure of 0.591atm and a temperature of 254 degree celcius, occupies a volume of 649mL. If the gas is cooled at constant pressure until its volume is 542mL, the temperature of the gas sample will be------- degree celcius.
Q2. A sample of nitrogen gas at a pressure of 781mmhg and a temperature of 24 degree celcius, occupies a volume of 11.9liters. If the gas is cooled at constant pressure to temperature of -6 degree celcius, the volume of the gas sample will be -----L.
What is oxidation state? How can find out the oxidation state of particular element? Explain its trend in the group and period, give reasons
In group 16 since, the electronegativity decreases so tendency to exhibit -2 oxidation state decreases as we go down the group. why this is so? How electronegativity and oxidation state link with each other.
A glass container is sealed with a gas at 0.800atm pressure and at 25 degree Celsius the glass container sustain pressure of 2 atmosphere calculate the temperature to which gas can be heated before bursting the container.
A block of metal has a width of 3.2 cm, a length of 17.1 cm, and height of 3.5 cm. Its mass is 1.2 kg. Calculate the density of the metal.
Chester makes 1L of a 0.01 M HCL solution as well as measure the pH. Burt then adds 5.80 g of sodium chloride to Chester's solution and measures the pH. Compute the difference between the two pH values obtained.
Use the Henderson Hasselbalch Equation to calculate the pH after the addition of 0.10 M NaOH to this solution, assuming no change in volume?
Problem- What information about the mechanism of catalysis by trypsin would not be apparent from the protein's amino acid sequence, but only from the 3-dimensional structure illustrated
A 0.300 M solution of an acid, HZ, has a pH = 1.301. What is the value of the ionization constant, Ka, for this acid
Draw the correct structure for (3S,4S)-3,4-dimethylhexane. Show stereochemistry clearly. To ensure proper grading, explicitly draw all four groups, including wedge/dash bonds
a fixed quantity of gas at 21 exhibits a pressure of 730 and occupies a volume of 4.40. use boyles law to calculate the
a.the density of liquid oxygen at its boiling point is 1.14 and its heat of vaporization is 213.nbsphow much energy in
Your task is to replicate the Crystal structure of H10-2-G3. It is not just a matter of making a cartoon and highlighting side chains. Some of the atoms in the side chains are missing exposing only from CB
