Answer:
Final temperature of calorimeter is 25.36^{0}\textrm{C}
Explanation:
Molar mass of anethole = 148.2 g/mol
So, 0.840 g of anethole = 
of anethole = 0.00567 moles of anethole
1 mol of anethole releases 5539 kJ of heat upon combustion
So, 0.00567 moles of anethole release 
of heat or 31.41 kJ of heat
6.60 kJ of heat increases 
temperature of calorimeter.
So, 31.41 kJ of heat increases 
or 
temperature of calorimeter
So, the final temperature of calorimeter = 
Answer:
It is Though the transfer of charges from one object to another, or (A).
Answer:
Identical
Explanation:
Both compounds are identical. If you rotate the compound on the left 60 degree anticlockwise you will get the compound on the right.
These are not isomers of each other because they have same structural and molecular formulas.
Also, they are related to each other because they are the same
Answer:
0.89M
Explanation:
Because moles of solute do not change, we can write
M1V1 = M2V2
M - molarity, V - volume of solution
2.0M*200mL = M2*450mL
M2 = 0.89 M
