I think it would be 2,510 kJ, or 2,510,000 J.
1 cm of copper. This is because copper atoms are heavier than aluminum atoms.
The land and the way the heat changes around there
None of them really sound like the answer, but my best guess would probably be the second one. It doesnt give much info.
61g/mol
Explanation:
The empirical formula of compound is its simplest formula. It shows the simplest ratio by which the atoms are combined.
In the formula C₄H₁₀O₄
we have:
4 moles of carbon 10 moles of hydrogen 4 moles of Oxygen;
4 : 10 : 4
The simplest ratio can be obtained by dividing through by the highest common factor which is 2;
4/2 10/2 4/2
2 5 2
the empirical formula is C₂H₅O₂
The formula mass is the sum of the atomic weights;
C₂H₅O₂ = (2 x 12) + (5x1) + (2x 16) = 24 + 5 + 32 = 61g/mol
