the correct order of decreasing X-O-X bond angle is(X=H,F or Cl):
(A)H2O>Cl2O>F2O
(B)Ci2O>H2O>F2O
(C)F2O>Cl2O>H2O
(D)F2O>H2O>Cl2O
right answer is B how?
H2O<Cl2O<F2O answer is A F2O, Cl2O and H2O are all similar from the point of view that a single oxygen atom forms two single bonds with other atoms. In all...

C + 2 H2O CH4 + CO2 C + H2O CO + H2 ∆H = +131.3 kJ CO + H2O CO2 + H2 ∆H = -41.2 kJ CH4 + H2O 3 H2 + CO ∆H = +206.1 kJ
131.3+-41.2-206.1= 116kJ

Given the following information, what would the overall order of the reaction be?
C6H5N2Cl(aq)+H2O(l) C6H5OH(aq)+N2(g)+HCl(aq)
Rate=k[C6H5N2Cl]1
[H2O]0
Rate=k*[C6H5N2Cl]1*[H2O]0overall order of the reaction = 1 + 0 = 1Answer: 1

Using CO2 = -393.5 kj/mol and H2O = -285.8 kj/mol determine delta H for C4H10
The combustion of butane (C4H10)can be determined as following:C4H10 + 6.5O2 --> 4CO2 + 5H2OAccording to the equation:ΔHreaction = ΔHproducts - ΔHreactantsFrom here:ΔHreactants = ΔHproducts - ΔHreactionAs ΔHreaction = -2877.5 kJ/mol (table value)...

The reaction A + B + C > D + E is first order for reactant A, first order for B, and second order for C. What is the rate law equation for this reaction?
A first-order reaction has a rate proportional to the concentration of one reactant. rate=k[A], rate=k[B] A second-order reaction has a rate proportional to the product of the concentrations of two...
