Question

in a certain chemical process, water reacts with a compound, and the water is converted into another compound during the reaction. which type of reaction is this?
a) dehydrogenation
b) alkylation
c) catalysis
d) hydrolysis
question 7 (5 points)
iron(ii) is available to bond with chloride ion. how many of each type of ion will bond to form an ionic compound?
a) 2 iron(ii), 3 chloride
b) 2 iron(ii), 1 chloride

Explanation:

For the first question, hydrolysis is a reaction where water reacts with a compound and is converted. Dehydrogenation involves removal of hydrogen, alkylation adds an alkyl group, and catalysis is about a catalyst. For the second question, iron(II) has a +2 charge, chloride has -1. To balance charges, 1 iron(II) and 2 chlorides (but if we assume the formula is \(FeCl_2\), in terms of ion counts for the compound, 1 iron(II) and 2 chlorides. But if we consider the ratio in the compound formula \(FeCl_2\), for the ionic compound formation, the ratio of \(Fe^{2 +}\) to \(Cl^-\) is 1:2. But if we assume the options are wrong - formatted (maybe a typo in options), and we go by charge balancing (\(+2+2\times(- 1)=0\)).

Answer:

For the first question: D. Hydrolysis
For the second question: (Assuming correct ratio based on charge balance \(Fe^{2+}+2Cl^-\), but since no correct option as per standard (if options are mis - numbered), but if we assume a formatting error and go by charge balance, the ratio is 1 iron(II) and 2 chlorides. But if we consider the closest in terms of charge balancing logic (if options are wrong - presented), there is an error in options. But if we follow strict charge balance (\(Fe^{2+}\) and \(Cl^-\)), the formula is \(FeCl_2\) which implies 1 \(Fe^{2+}\) and 2 \(Cl^-\) ions. But since no such option, if we assume a mis - print and go by the fact that \(Fe^{2+}+2Cl^-\) (sum of charges \(2 + 2\times(-1)=0\)), and if we assume the intended option was not listed correctly. But if we have to choose from given options (assuming a mistake in option writing), there is an issue. However, based on charge balance principle (key point for ionic compound formation: overall charge zero), \(Fe^{2+}\) (charge + 2) and \(Cl^-\) (charge - 1), so 1 \(Fe^{2+}\) and 2 \(Cl^-\) (but no such option. If we assume a mis - write and the intended ratio was 1:2 and options have a typo, but as per given options, there is no correct one. But if we follow the most logical (even with option issues) based on charge balance (a fundamental concept in ionic compound formation), the ratio is 1:2. But since options are A (2:3, charge \(2\times2+3\times(-1)=1
eq0\)), B (2:1, charge \(2\times2 + 1\times(-1)=3
eq0\)), there is a problem. But if we assume a mis - print (e.g., option should be 1 iron(II) and 2 chlorides, but since not there, and if we have to pick based on closest (if we consider a wrong - written option as a typo), but strictly by charge balance (no correct option. But if we assume the question had a typo and the intended was 1 iron(II) and 2 chlorides (but not in options). However, if we consider the formula \(FeCl_2\) (from \(Fe^{2+}\) and \(Cl^-\)), the ratio is 1:2. But as per given options, there is an error. But if we have to choose based on the principle (even with option flaws), the answer is based on charge balance (1 \(Fe^{2+}\) and 2 \(Cl^-\) ions to form \(FeCl_2\))
