- (6.3)The volume of a gas is 0.953 L at 30.0 °C. If the gas is heated to 60.0 °C, what would be the volume of the gas (in L) at this temperature? O 1.05 L O 0.867 L O 1.91 L O 0.477 Larrow_forwarddoes it compare with the known melting and boiling point? (1) 9. The average kinetic energy of water molecules is a measure of the temperature of water. When the temperature of water remains constant the average kinetic energy of the molecules remains constant, even though the water is being heated by the Bunsen flame. So, energy is being taken in by the water, but it is not being used to increase the kinetic energy of the molecules. 9.1 What type of energy are the water molecules gaining during a phase change? (1) 9.2 Explain your reasoning (to question 9.1) with reference to the kinetic theory of matter. 10. Write the conclusion.

Determine if each of the following mixtures forms an unsaturated or saturated solution at 25 °C: (9.3) a. adding 10 g of LiCl to 15 g of H;O b. adding 25 g of LİCI to 50. g of H,0 c. adding 75 g of LiCl to 150. g of H,O ne on nearrow_forward6.(0-2) Black powder was invented in China in the 9th century. It was used as an explosive with propelling properties. Today it is used in fireworks, model rocket engines, and replica black powder weapons. Black powder consists of potassium nitrate (potassium nitrate, KN03), charcoal and sulfur. A variety of chemical reactions take place when this mixture is exploded. One of these is shown below. 2KNO, +S+ 30 → K, S+N, ↑+3C0, 1 Knowing that carbon makes up 15% of the black powder, calculate the total volume of gases (under normal conditions) released when 0.1 kg of black powder explodes. Assume that only the chemical reaction given above occurs.arrow_forward
