To measure the speed of a car, we use miles per hour (miles/hour or mi/h or mph). To measure the rate of a reaction we use molar
concentration per second (M/s).Part AImagine that you took a road trip. Based on the information in the table, what was the average speed of your car?Time Mile marker3:00 pm 208:00 pm 241Express your answer to three significant figures and include the appropriate units. Use mi as an abbreviation for miles, and h for hours, or mph can be used to indicate miles per hour.Part BNow consider the following reaction and data:H2+2ICl→2HCl+I2Time(s) I2 concentration(M)5 1.1115 1.83What is the average rate of formation of I2?Express your answer to three decimal places and include the appropriate units.Part CBased on your answer to Part B, what is the average rate of formation of HCl?Express your answer to three decimal places and include the appropriate units.
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.
