0,245 kg of gas with a density of 1,2 kg/m is compressed adiabatically from a pressure of 150 kPa to a pressure of 800 kPa. R = 0,293 kJ/kg. K and Cp = 1,005 kJ/kg. K. Calculate the following: 2.1 The adiabatic index 2.

A package of chocolate instant pudding contains 3080mg of sodium. how many grams of sodium is that

Aqueous ammonia is commercially available in a solution that is 28% by mass ammonia. What is the mole fraction of ammonia in such a solution?

The following charges on individual oil droplets were obtained during an experiment similar to Millikan's. Determine a charge for the electron On C, coulombs), and explain your answer: - 3.204><10 - 19 C; - 4.806x10-19 C; ~8.0le10-19 C; - 1.

After 1.60 mol of NH3 gas is placed in a 1600-cm3 box at 25°C, the box is heated to 500 K. At this temperature, the ammonia is partially decomposed to N2 and H2, and a pressure measurement gives 4.85 MPa.

The freons are a class of compounds containing carbon, chlorine, and fluorine. while they have many valuable uses, they have been shown to be responsible for depletion of the ozone in the upper atmosphere.

How will you describe the pathway of oxygen in the breathing system?

Match the standard reduction potentials for each half reaction and the electric potential for the voltaic cell.

Which of the following is NOT a unit used to measure temperature? Question 20 options: Kelvin Watt Celsius Fahrenheit

If the reaction to form water were written h2 (g) + 12o2 (g) →h2o (g), would you expect the same value of δh as in equation 2h2 (g) + o2 (g) ⟶2h2o (g) δh=-483.6kj?
