Froggy Jumps TERM 1 EXAMOnline version CHEMICAL REACTION AND EQUATION by Dee Rivera 1 Which statement best describes what happens to atoms during a chemical reaction? a Atoms disappear when products form. b Atoms are rearranged to form new substances. c New atoms are created from released energy. 2 Which scientific law states that the total mass remains constant during a chemical reaction in a closed system? a Law of definite proportions b Law of conservation of mass c Law of multiple proportions 3 Why must a correctly written chemical equation contain the same number of each kind of atom on both sides? a Atoms have equal sizes in every substance. b Reactants and products must have equal volumes. c Matter is conserved as atoms are rearranged. 4 A sealed flask has a mass of 185.6 g before vinegar and baking soda are mixed. What should its mass be after the reaction is complete? a Less than 185.6 g because a gas formed b Exactly 185.6 g because the system is closed c More than 185.6 g because new substances formed 5 A group mixes substances in an open cup and records a lower final mass. Which evaluation best explains the result and improves the investigation? a Mass was destroyed; repeat with a larger cup. b The balance failed; estimate the missing mass. c A gas escaped; repeat in a sealed setup and compare total mass. 6 Which substance is a common acid? a Hydrochloric acid b Sodium hydroxide c Sodium chloride 7 What color does blue litmus paper usually turn in an acidic solution? a Blue b Green c Red 8 A solution turns red litmus paper blue. How should the solution be classified? a Acidic b Basic c Neutral salt only 9 Four clear liquids are tested. Sample P turns blue litmus red; Q turns red litmus blue; R changes neither; S turns blue litmus red. Which sample is most likely sodium hydroxide? a P b Q c R 10 A student must distinguish dilute hydrochloric acid, sodium hydroxide, and saline solution using red and blue litmus. Which plan gives the most defensible identification? a Smell each sample and confirm with one litmus paper. b Use only red litmus and label unchanged samples saline. c Test each with both papers: an acid turns blue litmus red, a base turns red litmus blue, and saline changes neither paper. 11 When balancing an equation, which part may be changed? a Element symbols b Subscripts in formulas c Coefficients before formulas 12 What is the coefficient of O2 in the balanced equation 2H2 + O2 -> 2H2O? a 1 b 2 c 3 13 Why is H2 + O2 -> H2O not balanced? a Water must always have a coefficient of 1. b The reactants contain more kinds of elements. c There are two oxygen atoms on the left but one on the right. 14 Which equation shows equal numbers of sodium and chlorine atoms on both sides? a Na + Cl2 -> NaCl b 2Na + Cl2 -> 2NaCl c Na2 + Cl2 -> NaCl 15 Balance: N2 + H2 -> NH3. Which coefficient set is correct for N2, H2, NH3? a 1, 1, 1 b 1, 2, 2 c 1, 3, 2

Which statement best describes what happens to atoms during a chemical reaction?

Which scientific law states that the total mass remains constant during a chemical reaction in a closed system?

Why must a correctly written chemical equation contain the same number of each kind of atom on both sides?

A sealed flask has a mass of 185.6 g before vinegar and baking soda are mixed. What should its mass be after the reaction is complete?

A group mixes substances in an open cup and records a lower final mass. Which evaluation best explains the result and improves the investigation?

Which substance is a common acid?

What color does blue litmus paper usually turn in an acidic solution?

A solution turns red litmus paper blue. How should the solution be classified?

Four clear liquids are tested. Sample P turns blue litmus red; Q turns red litmus blue; R changes neither; S turns blue litmus red. Which sample is most likely sodium hydroxide?

A student must distinguish dilute hydrochloric acid, sodium hydroxide, and saline solution using red and blue litmus. Which plan gives the most defensible identification?

When balancing an equation, which part may be changed?

What is the coefficient of O2 in the balanced equation 2H2 + O2 -> 2H2O?

Why is H2 + O2 -> H2O not balanced?

Which equation shows equal numbers of sodium and chlorine atoms on both sides?

Balance: N2 + H2 -> NH3. Which coefficient set is correct for N2, H2, NH3?
