A chemistry student was asked to calculate the number of moles of iron required to react with 1.20 mol of oxygen to produce iron(III) oxide. His calculations is shown below. Is the student correct? Use evidence to support your answer.

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system

Large helium-filled balloons are used to lift scientific equipment to high altitudes. what is the pressure inside such a balloon if it starts out at sea level with a temperature of 10.0ºc and rises to an altitude where its volume is twenty times the original volume and its temperature is – 50.0ºc ?

Volume is a measurement of how fast particles of a substance are moving
