What would be the balanced chemical equation for the complete combustion of butane ( C4H10 .)
1 answer:
The balanced chemical equation b. 2 C₄H₁₀ + 13 O₂ ⇒ 8 CO₂ + 10 H₂O
<h3>Further explanation</h3>Given
Butane (C₄H₁₀)
Required
Balanced equation
Solution
Formula
Hydrocarbon combustion reactions (specifically alkanes)
In the combustion process, the compound in the reactants is Oxygen (O₂)
If the oxygen needed for combustion is sufficient (or excess) then the combustion results are in the form of CO₂ and H₂O, but if not enough, CO and H₂O will be obtained.
The only answer that contains O₂ in the reactants is option B

Answer:
Molarity of solution is 0.612 mol/L
Explanation:
Number of moles of a substance = (mass of substance)/(molar mass of the substance)
Molar mass of = 214 g/mol
So, 562 g of =
moles of
= 2.63 moles of
Molarity of a solution = (number of moles of solute in solution)/(total volume of solution in liter)
Here solute is and solvent is water
Total volume of solution is 4.30 L
So, molarity of solution =
= 0.612 mol/L
Answer:
The correct option is;
A) x = 2, y = 1
Explanation:
Here we have
....................(1)
....................(2)
..............(3)
From experiment (1), (2) it is observed that [A] is held constant and [B] is doubled of which the rate is also observed to be doubled, therefore, when you double a reactant which result in the rate being doubled, the order of the reaction with respect to the reactant is order 1, therefore, y = 1.
Similarly between reaction (2) and (3) when the concentration of the reactant B is doubled and A is held constant the rate of the reaction is multiplied by a factor of 4, therefore, the reaction with respect to that reactant is order 2, therefore, x = 2.
Therefore, the correct option is x = 2, y = 1.
