Ch+8+Chemical+Reactions


 * High School Content Expectations **** (HSCE) **
 * Ch 8 Chemical Equations and Reactions **
 * Ch 8:1 Describing Chemical Reactions**
 * C3.4A – ** Use the terms endothermic and exothermic correctly to describe chemical reactions in the laboratory.
 * C3.4B – ** Explain why chemical reactions will either release or absorb energy.
 * C5.2B –** Distinguish between chemical and physical changes in terms of the properties of the reactants and products.
 * Ch 8:2 Balancing Chemical Equations**
 * C5.2A – ** Balance simple chemical equations applying the conservation of matter.
 * C5.2 – ** Chemical changes can occur when two substances, elements, or compounds interact and produce one or more different substances whose physical and chemical properties are different from the interacting substances. When substances undergo chemical change, the number of atoms in the reactants is the same as the number of atoms in the products. This can be shown through simple balancing of chemical equations. Mass is conserved when substances undergo chemical change. The total mass of the interacting substances (reactants) is the same as the total mass of the substances produced (products).
 * Ch 8:3 Classifying Chemical Reactions**
 * C5.2x – ** A balanced chemical equation will allow one to predict the amount of product formed.
 * C5.6b – ** Predict single replacement reactions.

= = Science Geeks Reaction TypesWrite out the reaction and include the reaction type. Check and submit your answers.

Include the reaction, what tool you used to decide whether it happens or not and the explantion of your response. Check your answers on the site.
example response Rxn including states of matter 2 NaBr (aq) +I2(g) → 2NaI +Br2(g) Rxn type Single replacement or Double Replacement Tool used Activity series p. 832 or Solubility chart p. 473 Explanation No the rxn will not occur because Iodine won’t replace Bromine because it is less reactive.
