What else can I help you with?
Ask us anythingUse the reaction I2(s) I2(g) H 62.4 kJmol S 0.145 kJ(molK) for question 10. What can be said about the reaction at 500 K?
At 500 K, the reaction will favour the formation of gaseous I2 since the positive change in enthalpy indicates the reaction is endothermic. The positive change in entropy suggests an increase in disorder, further favoring the formation of gaseous I2 at higher temperatures.
Which direction of the reaction is favored at 298 K?
At 298 K, the direction of a reaction is favored based on whether it is exothermic or endothermic. If the reaction is exothermic, it is favored in the direction that consumes heat, while for an endothermic reaction, it is favored in the direction that produces heat. The reaction will proceed in the direction that helps to minimize the overall energy of the system.
What is the coefficient distribution F of I2 between H2O and CCL4?
The coefficient distribution F of I2 between H2O and CCl4 refers to the partitioning of I2 between the two solvents. It quantifies the relative solubility of I2 in each solvent and is determined experimentally using a partition coefficient measurement. The coefficient distribution F is calculated as the concentration of I2 in CCl4 divided by the concentration of I2 in H2O at equilibrium.
How do you write a equation for idometry and iodimetry titration reaction?
Iodometry & iodimetry Iodometry An application of iodine chemistry to oxidation-reduction titrations for the quantitative analysis in certain chemical compounds, in which iodine is used as a reductant and the iodine freed in the associated reaction is titrated
Is I2 a compound or an element?
I2 is an Element. It is the chemical symbol for molecular iodine.
What is the value of 2i raised to the third?
(2i)3 = 8i3 = 8(i2)(i) = 8(-1)(i) = -8i
If x plus y equals -2 and xy equals 2 then what is x cubed plus y cubed?
x + y = -2 ∴ y = -2 - x xy = 2 ∴ x(-2 - x) = 2 ∴ -2x - x2 = 2 ∴ x2 + 2x + 2 = 0 ∴ x2 + 2x + 1 = -1 ∴ (x + 1)2 = -1 ∴ x + 1 = i ∴ x = i - 1 recall: y = - 2 - x ∴ y = - 2 - (i - 1) ∴ y = -2 - i + 1 ∴ y = - i - 1 ∴ x3 + y3 = (i - 1)3 + (- i - 1)3 = (i - 1)(i2 - 2i + 1) + (- i - 1)(i2 + 2i + 2) = i3 - 2i2 + i - i2 + 2i - 1 - i3 - 2i2 - 2i - i2 - 2i - 2 = i3 - i3 - 2i2 - i2 - 2i2 - i2 + i + 2i - 2i - 2i - 1 - 2 = -6i2 - i - 3 = 3 - i
Which reaction occurs when bromine is added to an aqueous solution of iodide ions?
The bromine oxidizes iodide ions to produce iodine and bromide ions. The overall reaction is 2I- + Br2 → I2 + 2Br-.
What is the balanced reaction equation between sodium thiosulfate and molecular iodine?
2KI+MnO_2+3H_2 SO_4→2I+2KHSO_4+MnSO_4+2H_2 O
What is the standard form of the expression I2 plus 1?
It is 2I + 1. The coefficient is put before the variable.
NaI plus Cl2 - NaCl plus I2?
4
What is the chemical formula for magnesium and iodine?
Mg2+ + 2I- ---> MgI2
Is ferric iodide possible?
Maybe, but not very stable because 2Fe3+ + 2I- --> 2Fe2+ + I2 is a favourable forward reaction (positive difference in (standard) electrode potential scale 73 (Fe3+) - 62 (I2) = 11 eV
What chemical is oxidized in the following reaction Br2(l) plus 2I-(aq) and rarr 2Br-(aq) plus I2(s)?
Bromine is the oxidizing element.
What is the net ionic equation for the reaction of chlorine gas into a aqueous solution of sodium iodide?
The net ionic equation for the reaction of chlorine gas with aqueous sodium iodide is: Cl2 + 2I- -> 2Cl- + I2. This represents the exchange of ions between chlorine and iodide ions, resulting in the formation of iodine gas and chloride ions.
Can x to the fourth power ever result in a negative number?
no even exponent of a real number can ever result in a negative number. If x is a complex number with the real and imaginary part having the same magnitude, then taking that to the fourth power will result in a real number, which is negative.Example: (2 + 2i)4, or (-2 + 2i)4, or (2 - 2i)4, or (-2 - 2i)4, Just take (2 - 2i)4, as one to see how it works. First take (2 - 2i)2, then we'll square that result.(2 - 2i)2 = 4 - 4i - 4i + 4i2 , but i2 is -1, so we have -8i, then square that is 64i2 which is -64.
