Solve :-

a) 2NO(g) + O2(g) → 2NO2(g)

ΔH1 = −116 kJ

b) 2N2(g) + 5O2(g) + 2H2O(l) → 4HNO3(aq)

ΔH2 = −256 kJ

c) N2(g) + O2(g) → 2NO(g)

ΔH3 = +183 kJ

Propane (C3H8) is burned with excess air to ensure complete combustion. If 55 kg of CO2 and 15 kg of CO are obtained when propane is completely burned with 500 kg of air, determine the following:

- Mass of propane burnt.
- Percent excess air.
- Composition of product gas.

Reactions are : C3H8 + 5 O2→ 3 CO2 + 4 H2O

C3H8 + 3.5 O2→ 3 CO+ 4 H2O

For light of wavelength 589 nm, calculate the critical angles for the following substance when surrounded by air.

polystyreneWhile looking at her image in a cosmetic mirror, Dina notes that her face is highly magnified when she is close to the mirror, but as she backs away from the mirror, her image first becomes blurry, then disappears when she is about 40.0 cm from the mirror, and then inverts when she is beyond 40.0 cm. Based on these observations, answer the following questions about the mirror.

(a) What type of mirror does Dina have? convexconcave(b) What is the focal length of the mirror?

Bank robbers leave the bank with the bounty. The cops get alerted right away, but it takes them 3 minutes before they start in hot pursuit. The police station is 10 miles down the road from the bank in the direction opposite to that in which the robbers are heading. If the robbers travel at 95 mph how fast must the cops go to catch them before they reach the state line 45 miles away? Round your answer to nearest mile per hour.

Enumerate the possible values of the total angular momentum j and mj for states in which the orbital angular momentum l = 3 and the spin s = 1/2.

Why are lower energy photons filtered out in medical x-ray imaging?

A. They are quickly attenuated by tissue and therefore do notpenetrate the body well.

B. They do not contribute to the image formation.

C. They only contribute to the patient exposure to the harmfulradiation.

D. All of the above are reasons why these photons are filteredout.

The chemical potential for a conduction electron in a certain metal is −0.3 eV. Electrons are fermions, so no more than one electron may occupy a given state (n = 0 or 1 only). At room temperature (295 K), what is the probability that a state of energy −0.27 eV is (a) occupied, (b)un occupied?

The Earth's orbit around the sun is not a perfect circle; it is, in fact, elliptical. In January, the Earth is 147 million kiometers from the Sun. In July, the Earth is 152 kilometers from the Sun. If the tide-generating force from the Sun is F(sun)=1/r^2, how do you think the amplitude of the spring tides in winter would compare with those of the spring tides in the summer (assuming northern hemisphere seasonality)?

A railroad car containing explosive material is initially traveling south at a speed of 4.5 m/s on level ground. The total mass of the car plus explosives is 2.9x 10^4 kg. An accidental spark ignites the explosive, and the car breaks into two pieces, which then roll away along the same track. If one piece has a mass of 1.9x 10^4 kg and a final speed of 2.3 m/s toward the south, what is the final speed of the other piece?
