1. Find the maximum increase in density across a shock wave for a gas with γ = 1.4.
2. A blowdown wind tunnel is supplied by a large air reservoir where the pressure is constant at 1.014×105 P a and the temperature is constant at 15°C. The air passes through a working section of area 0.04 m2 and exits to a large vacuum vessel. Find the pressure, density, velocity and mass flow rate in the working section if the Mach number there is 4.0.
If 2.00g of N2 gas has a volume of 0.40L and a pressure of 6.0atm, what is its Kelvin temperature
if the experimenter uses a thermometer that reads 1.4C too high how will this affect the calculated molar mass.
A sample containing 42 ml of 0.0625 M NaBr was made by adding 37.8 ml of water to an initial solution of concentrated NaBr. Explain what the concentration of NaBr was in the initial solution
Explain why does the biodiesel product give several major peaks at different retention times (Rt), in its place of only one product peak
A box of volume 20.0 L contains 1.50 moles of an ideal gas. This gas initially consists of a single molecular species, X (molar mass of 42.0 g/mol), at a temperature of 25.0 °C.
Equivalence point was 18.46 mL and my second equivalence point was 33.185 mL. How to find the percent weight of Na2CO3 in the unknown using these two values?
What is the resolution of an electron microscope. What is the typical energy, velocity, momentum, and de Broglie wavelength of electrons typically used in the microscope
Calculate the binding energy of the 2s electron in iron and calculate the binding energy of the 2s electron in iron. Does the new energy agree better with experiment?
The electrochemical processes that occur in the rate limiting step of the corrosion of iron (oxidation of iron) are represented by the half-reactions
Problem- for the sequence [(O+N2 arrow NO+N)(1) or (NO+H arrow N + OH)(2)] reaction number (2) is the rate determining step. Is the statement true or false?
Explain solids, liquids and gases in terms of how they fill a container, Utilize your descriptions to identify the physical state at room temperature of the subsequent 1.helium in a toy balloon. 2. Mercury in a thermometer. 3. Soup in a bowl
