Speed = Distance / Time = 400 meters / 50 seconds = 8 m/s.

2H2 + O2 → 2H2O. 1 mole of water weighs 18 g, so 2 moles produce 36 g. Thus, 18 g of water is produced from 1 mole of O2.

2 moles of H2 and 1 mole of O2 produce 2 moles of H2O. The molar mass of water is 18 g/mol, so 2 moles produce 36 g.

The side opposite to the 30-degree angle is half the hypotenuse, so it is 10/2 = 5 cm.

In a 30-60-90 triangle, the sides opposite the 30 degrees and 60 degrees are in the ratio 1:√3.

Total resistance R_total = R1 + R2 = 4 Ω + 8 Ω = 12 Ω. Using Ohm's Law, I = V/R = 12 V / 12 Ω = 1 A.

Expected male patients = 70% of 400 = 0.7 * 400 = 280.

Let the angles be 2x, 3x, and 4x. Then, 2x + 3x + 4x = 180, so 9x = 180, x = 20. The largest angle is 4x = 80 degrees.

Total points scored = 25 points/set * 4 sets = 100 points.

In an adiabatic process, as the temperature decreases, the pressure also decreases due to the ideal gas law.

From 2 moles of Fe, 2 moles of FeCl3 are produced. Therefore, from 4 moles of Fe, 4 moles of FeCl3 are produced.
