Question 1 (true/false worth 2 points) (04.03 lc) when pb and alcl3 react together, lead (pb) can replace aluminum (al) in the compound because lead is lower on the activity series. true false question 2(multiple choice worth 4 points) (04.03 mc) which of the following equations has the correct products and is balanced correctly for a reaction between na3po4 and koh? na3po4 + 3koh → 3naoh + k3po4, because k retains the same charge throughout the reaction na3po4 + koh → na3oh + kpo4, because k increases in charge from 1+ to 3+ when it is replaced na3po4 + koh → 3naoh + k3po4, because k retains the same charge throughout the reaction na3po4 + koh → na3oh + k3po4, because k increases in charge from 1+ to 3+ when it is replaced question 3(multiple choice worth 4 points) (04.03 lc) which of the following is a single replacement reaction? ba(oh)2 + h2so4 → baso4 + 2h2o 2mg + o2 → 2mgo h2o+ co2 → h2co3 zn + h2so4 → znso4 + h2 question 4(multiple choice worth 4 points) (04.03 mc) sodium metal reacts with water to produce hydrogen gas. what best describes this reaction? a single replacement reaction takes place because sodium is less reactive than hydroxide ions. a double replacement reaction takes place because sodium is less reactive than hydroxide ions. a double replacement reaction takes place because sodium is more reactive than hydrogen. a single replacement reaction takes place because sodium is more reactive than hydrogen. question 5 (true/false worth 2 points) (04.03 lc) a single replacement reaction is a reaction in which one element replaces a similar element within a compound. true false question 6(multiple choice worth 4 points) (04.03 mc) the table shows the nature of reactants and products formed in a certain type of chemical reaction. nature of reactants and products reactants products metal + ionic compound metal + ionic compound which of the following is true about the type of chemical reaction? it is a single replacement reaction, and the anions in the two ionic compounds are different. it is a single replacement reaction, and the cations in the two ionic compounds are different. it is a double replacement reaction, and the anions in the two ionic compounds are different. it is a double replacement reaction, and the cations in the two ionic compounds are different.
