I send my congratulations to Luiz Inácio Lula da Silva on his election to be the next president of Brazil following free, fair, and credible elections. I look forward to working together to continue the cooperation between our two countries in the months and years ahead.
@SarahCorfield5 @doc_kristy This bring us to: 2 molecules of butane reacts with 13 molecules of oxygen (dioxygen). Is the same mole ratio, but easy to read in terms of “molecules”.
@SarahCorfield5 @doc_kristy is right. Your O2 ratio is the number of moles, not molecules. As the challenge fix the C4H10 as 1.0 mole, then the O2 must be 6.5 moles. To read the equation in “molecules” you better x2 the whole equation:
2 C4H10 + 13 O2 = 8 CO2 + 10 H2O
