is the final temperature of the given solution.
<u>Explanation</u>:
When heat is absorbed during reaction enthalpy is positive. To calculate amount of heat absorbed by solution:
To calculate no of moles of molar mass is 158.034 g/mol:
Hence quantity of heat can be calculated as given:
As considered that heat capacity of pure water is same as of solution (means to heat 1 gm of water by 1 degree Celsius the energy required) =
Now it is considered that due to dissolvation, no heat loss occurs and final temperature can be calculated by using specific heat capacity:
The final temperature of the solution is .

<u>Answer:</u>
Erlenmeyer flask can be heated up with a Bunsen burner.
<u>Explanation:</u>
A bunsen burner is a lab equipment that is used to heat things that aren't made up of anything flammable. The things that are to be heated with a bunsen burner are instruments of material like borosilicate like pyrex.
An Erlenmeyer flask that also goes by the names conical flask or even a titration flask can withstand a large amount of heat from the bunsen burner as it's made up of very thick and resistant glass. A graduated cylinder will not be able to withstand that amount of heat and a plastic pipette is sure to melt.
Answer:
Pure water has an acidity of about 7 on the pH scale. -is a chemical property of pure water. Pure water has an acidity of about 7 on the pH scale
