Answer: The given reaction is a double displacement reaction.
Explanation:
A chemical reaction equation in which both positive and negative ions of two different reactants are exchanged then it is called a double displacement reaction.
For example,
Here, hydrogen ions of are replaced by the sodium ions of . Also, sulfate ion of are replaced by oxygen ion of .
Thus, we can conclude that the given reaction is a double displacement reaction.
Answer:
Thermal energy.
Explanation:
Thermal energy is used to cook food. Thermal energy is heat. It's converted from either electrical potential energy or chemical potential energy, depending on the cooking appliance.
Answer:
Explanation:
The percent yield is the ratio of the actual yield to the theoretical yield.
- The actual yield is the amount obtained from performing a chemical reaction. For this problem, it is 14.8 grams.
- The theoretical yield is the potential amount from performing a chemical reaction at maximum performance. For this problem, it is 23.5 grams.
We can substitute the known values into the formula.
Divide.
Multiply.
The original measurements for the theoretical and actual yields have 3 significant figures, so our answer must have the same. For the number we calculated, that is the tenths place.
The 7 to the right, in the hundredths place, tells us to round the 9 up to a 0. Since we rounded up to 0, we have to move to the next place to the left and round the 2 up to a 3.
The percent yield is approximately <u>63.0 percent.</u>
They are very stable. they have a "full table" so to speak. they have no valance electrons. they do not give electrons and they do not take them either. there are very few if an elements that can be paired with noble gasses
