10: The total number is the product of the coefficient in front of the chemical formula and the subscript immediately following the symbol of the element asked about. If there is no subscript, a subscript of 1 is inferred.
The combustion of 2-dimethylpropane (C5H12) in oxygen involves the reaction between the hydrocarbon and oxygen gas to produce carbon dioxide (CO2) and water (H2O) as the main products. The balanced chemical equation for the combustion of 2-dimethylpropane is: C5H12 + 8O2 -> 5CO2 + 6H2O.
The balanced equation for the combustion of heptane (C7H16) with oxygen (O2) is: C7H16 + 11O2 → 7CO2 + 8H2O
The balanced chemical equation for the combustion of pentane C5H12 is: C5H12 + 8O2 → 5CO2 + 6H2O Therefore, for every 1 mole of pentane, 8 moles of oxygen gas are required. So, 0.100 mol of pentane will require 0.100 mol * 8 = 0.800 mol of oxygen gas to react completely.
If you mean atoms then two, if molecules one.
The heat combustion of pentane involves reacting pentane with oxygen to produce carbon dioxide and water, releasing heat energy in the process. The chemical equation for the combustion of pentane is: C5H12 + 8O2 -> 5CO2 + 6H2O + heat.
The balanced equation is: C5H12 + 8O2 → 5CO2 + 6H2O. Therefore, the coefficient for oxygen in the balanced equation is 8.
C5h12 + 8o2 --> 5co2 + 6h2o
In one (1) molecule CO2 there are 3 atoms ( 1 C-atom and 2 O-atoms), so in 5 molecules CO2 (5CO2) there are 5 x 3 (= 15) atoms. Thus fifteenis the answer to you.
The combustion of 2-dimethylpropane (C5H12) in oxygen involves the reaction between the hydrocarbon and oxygen gas to produce carbon dioxide (CO2) and water (H2O) as the main products. The balanced chemical equation for the combustion of 2-dimethylpropane is: C5H12 + 8O2 -> 5CO2 + 6H2O.
I get 2C6H14+19O2------->12CO2+14H2O
Burning pentane, C5H12, is a combustion reaction in which pentane and oxygen will react to form carbon dioxide and water. The chemical equation is C5H12 + 8O2 --> 5CO2 + 6H2O
The balanced equation for the combustion of heptane (C7H16) with oxygen (O2) is: C7H16 + 11O2 → 7CO2 + 8H2O
The balanced chemical equation for the combustion of pentane C5H12 is: C5H12 + 8O2 → 5CO2 + 6H2O Therefore, for every 1 mole of pentane, 8 moles of oxygen gas are required. So, 0.100 mol of pentane will require 0.100 mol * 8 = 0.800 mol of oxygen gas to react completely.

C5H10OH + 7O2 -> 5CO2 + 6H2O
First balance H and C:9 H --> 4.5*(2H in H2O) thus multplying by 2to get round figures gives:18 H = 9*(2H in H2O)2*(5 C) --> 10 (C in CO2)So now you've got this incompletely balanced equation (?? O2)2 C5H9O + ?? O2 --> 10 CO2 + 9 H2OThis counts for 10*2 + 9 * 1 Oxygen atoms at right side which will balance with 2 (O in C5H9O) and 27 (O in O2, thus 13.5 O2) and after multplying all molecular's by 2 to get round figures 4 C5H9O + 27 O2 --> 20 CO2 + 18 H2O Control:C: 4*5 = 20 C atoms = 20*1H: 4*9 = 36 H atoms =18*2O: 4*1 + 27*2 = 58 O atoms = 20*2 + 18*1
