Answer:
All the statements are correct but "all chemical reactions can be classified as one of the five general types".
Explanation:
Hello,
In this case, I assume you are looking for the wrong statement as long as the following ones are correct and matches with the foundations of chemical reactions:
- The only way to determine the products of a reaction is to carry out the reaction. This is clear, because after the chemical reaction is done, one identifies the products.
- Complete combustion has occurred when all the carbon in the product is in the form of carbon dioxide. This is clear due to a 100% conversion.
- A single reactant is the identifying characteristic of a decomposition reaction. All decomposition reactions have only one reactant which breaks into less complex species.
So the wrong statement is:
- All chemical reactions can be classified as one of five general types. This is wrong because there are four widely known chemical reactions: synthesis, decomposition, simple displacement and double displacement.
Best regards.
Change the core from wood to iron. This is because iron is a magnetic material while wood is not magnetic hence cant acquire magnetism. Other factors that would increase the strength of electromagnet would be; increasing the amount of electric current, and increasing the number of winding's.
<u>Answer:</u> The volume of solution is 1.13 L
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 2.09 M
Given mass of silver nitrate = 400. g
Molar mass of silver nitrate = 170 g/mol
Putting values in above equation, we get:
Hence, the volume of solution is 1.13 L
