Answer:
2.33 *10^1 g
Explanation:
.595 mol *39.0983 g/1 mol = 23.2634 > 2.33 *10^1 g
Answer:
C.One molecules with two ester ends
Explanation: In intramolecular Claisen condensations, reactions occur for 1,6 and 1,7 diesters, as these substances result in the formation of compounds containing five and six membered rings, respectively.
Answer:
The elements are Tin (Sn) and Lead (Pb)
Explanation:
They are 4+ and 2+
For the 2+, this happens because of the loss of the outermost two P electrons and for the 4+, because of the loss of two electrons from the P orbital and another two electrons from the s-orbital.
Answer:
The chloroplasts absorb the Sun's energy and convert it into glucose
Explanation:
This is a combustion reaction, which always has the hydrocarbon and oxygen as reactants and then carbon dioxide and water (which is steam in this case) as products.
C8H18 + O2 —> CO2 + H2O
Balance your carbons first. You want to get 8 carbons on both sides.
C8H18 + O2 —> 8CO2 + H2O
Now balance your hydrogens. You want 18 hydrogens on both sides.
C8H18 + O2 —> 8CO2 + 9H2O
Now balance your oxygens. You have 2 on the left and 25 on the right. The O2 reactant needs a coefficient of 12.5 to balance this.
C8H18 + 12.5O2 —> 8CO2 + 9H2O
However, you can’t have decimals for coefficients in a reaction. So, multiply everything by 2.
2C8H18 + 25O2 —> 16CO2 + 18H2O
Now, use your mole ratio of 18 mol H2O for every 2 mol C8H18 to solve.
5.74 mol C8H18 • (18 mol H2O / 2 mol C8H18) = 51.7 mol H2O (steam)
