Question 1 A)Which statement correctly describes the classification of chemical reactions into different categories?(1 point) Responses All reactions fit into a category, and some reactions can fit into more than one category. All reactions fit into a category, and some reactions can fit into more than one category. Not all reactions fit into a category, and some reactions can fit into more than one category. Not all reactions fit into a category, and some reactions can fit into more than one category. Not all reactions fit into a category, and a reaction can fit into only one category. Not all reactions fit into a category, and a reaction can fit into only one category. All reactions fit into a category, and a reaction can fit into only one category. All reactions fit into a category, and a reaction can fit into only one category. Question 2 A)In a synthesis reaction, two atoms of sodium (Na) combine with one molecule of chlorine gas (Cl2) to produce sodium chloride (NaCl). How many molecules of sodium chloride are produced?(1 point) Responses two two one one three three four four Question 3 A)In the decomposition of water, why is twice as much hydrogen as oxygen formed?(1 point) Responses Hydrogen atoms are twice the size of oxygen atoms. Hydrogen atoms are twice the size of oxygen atoms. Some oxygen gas escapes the reaction, and hydrogen gas is conserved. Some oxygen gas escapes the reaction, and hydrogen gas is conserved. Hydrogen gas has two atoms, and oxygen gas has one atom. Hydrogen gas has two atoms, and oxygen gas has one atom. There are two atoms of hydrogen and one atom of oxygen in a water molecule. There are two atoms of hydrogen and one atom of oxygen in a water molecule. Question 4 A)Which component is transferred between substances in an oxygen-reduction reaction?(1 point) Responses electrons electrons oxygen oxygen energy energy protons protons Question 5 A)In a chemical reaction, substance A transfers electrons to substance B. Which statement is correct?(1 point) Responses Substance B is oxidized and acts as the reducing agent. Substance B is oxidized and acts as the reducing agent. Substance A is oxidized and acts as the oxidizing agent. Substance A is oxidized and acts as the oxidizing agent. Substance A is reduced and acts as the reducing agent. Substance A is reduced and acts as the reducing agent. Substance B is reduced and acts as the oxidizing agent. Substance B is reduced and acts as the oxidizing agent.
