I think the highest theoretical temperature would be 36.5°C.
Hope I helped, sorry if not.
Answer:
0.595 ml
Explanation:
Mass=Volume*Denisty. Substituting what we know, 6.25=V*10.5. Solving for volume, you will get 0.595 ml.
The answer is B.
First write a balanced equation, which is
4Fe + 3O2 => 2Fe2O3.
Then divide the grams of Fe by the molar mass of Fe (16.7/55.85).
You now know the number of moles of Fe, so perform dimensional analysis.
(.299*2*159.70)/(4*1) = 23.9 g
The empirical formula : Na₂Cr₂O₇

Given
170 g sample contains :
29.84 g sodium, 67.49 g chromium, and 72.67 g oxygen
Required
The compound's empirical formula
Solution
mol ratio of elements :
Na : 29.84 : 23 g/mol = 1.297
Cr : 67.49 : 51,9961 g/mol = 1.297
O : 72.67 : 16 g/mol = 4.54
Divide by 1.297
Na : Cr : O = 1 : 1 : 3.5 = 2 : 2 : 7
