In a typical experiment, 100 mL of water is placed in the polystyrene foam cup and the initial temperature of the water recorded.5.05 g potassium nitrate, KNO3(s), is added to the water while stirring. The temperature of the solution falls and the minimum temperature acheived is recorded as the final temperature. The results of the experiment are shown in the table below. volume of water =100 mL mass of KNO3(s) = 5.05 g initial temperature = 25.0°C final temperature = 21.7°C. Determine the heat of solution of potassium nitrate.​

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l

Modern weaponry has increased the number of deaths in wars and violent conflicts.

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
