3. 4. Is the periodic table useful to you as a student? Justify your answer. If you were to create a simple product using metals, nonmetals, and metalloids, what would your product be like? Sketch the design and composition of your product. Then, briefly explain what properties of each material are utilized in each part of the product.
Chemical reactions occur when molecules or atoms collide in a way that the bonds between atoms break and new bonds form. Breaking the bonds of the reactants requires energy, whereas bond formation releases energy. Select the true statements regarding energy changes during a reaction. When the activation energy is high, the reaction rate is fast. If the heat of reaction, AH, is positive, the energy of the products is lower than the energy of the reactants and the reaction is exothermic. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. The energy of a collision between atoms or molecules must be greater than or equal to the activation energy, Ea, for bonds to be broken. Increasing the concentration of reactants increases the number of collisions, and the reaction goes faster. Reactants must collide with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur. The activation…
