Interpretation:
In the statement, “Your body converts excess intake of food into fat molecules”, whether a
(b)
Interpretation:
In the statement, “Sodium reacts with water”, whether a chemical reaction is releasing energy and causing work to be done or an outside source of energy is forcing a chemical reaction to occur has to be decided.
(c)
Interpretation:
In the statement, “Sodium azide in an automobile air bag decomposes, causing the bag to inflate”, whether a chemical reaction is releasing energy and causing work to be done or an outside source of energy is forcing a chemical reaction to occur has to be decided.
(d)
Interpretation:
In the statement, “An egg is hard-boiled in a pan on your kitchen stove”, whether a chemical reaction is releasing energy and causing work to be done or an outside source of energy is forcing a chemical reaction to occur has to be decided.

Chemistry: The Molecular Science
- As a child plays on a swing, at what point in her movement is her kinetic energy the greatest? At what point is potential energy at its maximum?arrow_forwardChlorine dioxide, ClO2, is a reddish yellow gas used in bleaching paper pulp. The average speed of a ClO2 molecule at 25C is 306 m/s. What is the kinetic energy (in joules) of a ClO2 molecule moving at this speed?arrow_forwardParticles in the illustration below undergo a chemical change. Which among the remaining boxes, a through d, can represent the products of the chemical change? If a box cannot represent the products of the chemical change, explain why. a b c darrow_forward
- Explain the economic importance of conversions between different forms of energy and the inevitability of losses in this process.arrow_forwardThe flashlight in the photo does not use batteries. Instead, you move a lever, which turns a geared mechanism and finally results in light from the bulb. What type of energy is used to move the lever? What type or types of energy are produced?arrow_forwardBicycling Describe the energy conversions that occur when a bicyclist coasts down a long grade, then struggles to ascend a steep grade.arrow_forward
- A particulate-level illustration of the reaction AB+CDAD+CB is shown below. a Identify the reactants and products in this reaction. b Is the change shown chemical or physical? c Is the mass of the product particles less than, equal to, or greater than the mass of the reactant particles? d If the reaction takes place in a container that allows no energy to enter or leave, how does the total energy in the container after the reaction compare with the total energy in the container before the reaction?arrow_forwardA piece of iron was heated to 95.4C and dropped into a constant-pressure calorimeter containing 284 g of water at 32.2C. The final temperature of the water and iron was 51.9C. Assuming that the calorimeter itself absorbs a negligible amount of heat, what was the mass (in grams) of the piece of iron? The specific heat of iron is 0.449 J/(gC), and the specific heat of water is 4.18 J/(gC).arrow_forward
