100 Which sample would contain more atoms: 12g of C or 12g of Mg? Why? 12g of C, Carbon atoms have less mass ∴ 12g of each, the smaller atom sample will contain a greater number of atoms.	100 Which graph best represents the best thermal equilibrium graph to represent mixing 200mL of 90°C water with 50mL of 20°C waterm,A sample of calcium has a mass of 80 g, how many moles are present? here is a larger volume of the higher temperature water, the equilibrium temperature will be closer to the higher temperature water,2 moles ca
200 What is evidence a chemical change occured? Color change, bubbles, temperature change, precipitate	200 now that you have avoided being grounded you get greedy and decide to add more sugar to the drink. How can you dissolve more sugar? 100 g of water was heated from 30C to 80C. The specific heat of water is 4.18 J/g*C. increas the tempature 20,900 j
300 List three intensive properties… List three extensive properties. Color, density, reactivity, state of matter, ect. Mass, volume, length	300 What are three ways to increase the volume of a balloon. The number of particles increases Lower pressure outside balloon Warm the balloon
400 Why can intensive properties be used to identify a substance? Why cannot extensive properties be used to identify a substance? They do not change based on amount They do change based on amount so it tells you almost nothing about composition without further study
500 Describe the change that occurs between points B → C. 00 gram block of copper at 20 ∘C lowered into 100 grams of water at 100 ∘C. Heat will flow from ____ to ______ until it reaches ________? The kinetic energy is constant & potential energy increases 100 gram block of copper at 20 ∘C lowered into 100 grams of water at 100 ∘C. Heat will flow from ____ to ______ until it reaches ________?
