Answer:
0.00079
When you round 0.000789 to 2 significant figures you would get
0.00079
because the zeros are just place holders if they are right after the decimal and don't have other numbers between them
then 789 rounds up to 790, which is 79

Answer:
Explanation:
Hello.
In this case, for this calorimetry problem, since the acetylene is burned into the calorimeter causing a temperature increase, we can infer that the combustion of acetylene releases heat which is absorbed by the calorimeter, therefore, the following equation can be written:
Which can be written in terms of the energy of combustion and moles of the acetylene and the heat capacity and temperature change of the calorimeter:
Thus, since the molar mass of acetylene is 26.04 g/mol, the resulting energy of combustion of the acetylene turns out:
