9.34 A copper nail and an iron nail of the same mass and initially at the same room temperature are both put into a vessel containing boiling water. Which one would you expect to reach 100°C first? Why?
A helium-filled balloon spontaneously deflates overnight as He atoms diffuse through the wall of the balloon. Describe the redistribution of matter and/or energy that accompanies this process.
You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at the same pressure and temperature): 1. volume gas X + 2 volumes gas Y2 volumes compound I 2. volumes gas X + 1 volume gas Y2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.
What is the chemical element? X

C) Mass may be destroyed but not energy. D) Energy may be destroyed but not matter. E) The total mass and energy is constant.
The energy associated with the motion of particles in a substance is called chemical energy. heat. temperature. electrical energy. potential energy.
The symbol of K+ represents one?
Which of the following is correct regarding the laws of energy?a. Energy cannot be created or destroyed.b. Energy can be changed from one form to another.c. Energy is lost as heat when it is converted from one form to another.d. All of these are correct.
A 29.300 g piece of unknown metal was heated in a hot water bath at 99.20°C. The hot metal was then transferred to a coffee-cup calorimeter [Ccal = 21.0 J/°C] containing 50.0 mL of water. Time Temperature data was collected and plotted. From the plot, the initial and final temperatures for the water were determined to be 22.50°C and 26.89°C, respectively. Calculate the molar mass of the metal and identify it using the periodic table.
How does this formula (e = mc2) relate energy to matter?
If the mass of the hot water is -67.46 and initial temperature of hot water is 51.0 and mass of cold water is 52.27 and final temperature of the water is 39.0 and temperature of the cold water is 21.2 predict the final temperature of water
Using white and black circles to represent different kinds of atoms, make a drawing that accurately represents each sample of matter: a solid element, a liquid compound, and a heterogeneous mixture. Make a drawing (clearly showing before and after) depicting your liquid compound undergoing a physical change. Make a drawing depicting your solid element undergoinga chemical change.
