Answer:
10.56 g
Explanation:
C4H10(g) + 13/2O2 (g) -------> 4CO2(g) + 5H2O(l)
Number of moles of butane = 3.49g/ 58 g/mol = 0.06 moles
1 mole butane yields 4 moles of CO2
0.06 moles of butane = 0.06 × 4/1 = 0.24 moles of CO2
Number of moles of oxygen = 17.1g/32g/mol = 0.53 moles of oxygen
6.5 moles of oxygen yields 4 moles of CO2
0.53 moles of oxygen yields 0.53 × 4/6.5 =0.33 moles of CO2
Butane is the limiting reactant
Theoretical yield of CO2 = 0.24 moles × 44g/mol = 10.56 g
I believe the percent yield is 56% if going by the formula of mass of actual yield/theoretical yield x 100%/
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.
Answer : The number of moles of HCl neutralize is, 0.00824 moles.
Explanation :
The given balanced chemical reaction is:
First we have to calculate the moles of 
Molar mass of = 144 g/mol
Now we have to calculate the moles of HCl.
From the balanced chemical reaction we conclude that,
As, 1 mole of react with 4 moles of HCl
So, 0.00206 mole of react with 
moles of HCl
Thus, the number of moles of HCl neutralize is, 0.00824 moles.
The organism could adapt over time and find another way to satisfy this need, it could move to a new location, or the organism could eventually die off.
