Balance the following equation in basic solution, using the lowest possible integer coefficients. What is the coefficient of wat

zalisa [80]

Answer:

Balanced equation: $2Cr(OH)_{3}(s)+3H_{2}O_{2}(aq.)+4OH^{-}(aq.)\rightarrow 2CrO_{4}^{2-}(aq.)+8H_{2}O(l)$

The coefficient of water is 8

Explanation:

Oxidation: $Cr(OH)_{3}(s)\rightarrow CrO_{4}^{2-}(aq.)$

Balance O and H in basic medium: $Cr(OH)_{3}(s)+5OH^{-}(aq.)\rightarrow CrO_{4}^{2-}(aq.)+4H_{2}O(l)$

Balance charge: $Cr(OH)_{3}(s)+5OH^{-}(aq.)-3e^{-}\rightarrow CrO_{4}^{2-}(aq.)+4H_{2}O(l)$ ......(1)

Reduction: $H_{2}O_{2}(aq.)\rightarrow H_{2}O(l)$

Balance O and H in basic medium: $H_{2}O_{2}(aq.)\rightarrow 2OH^{-}(aq.)$

Balance charge: $H_{2}O_{2}(aq.)+2e^{-}\rightarrow 2OH^{-}(aq.)$ .....(2)

$[2\times equation(1)]+[3\times equation(2)]:$

$2Cr(OH)_{3}(s)+3H_{2}O_{2}(aq.)+4OH^{-}(aq.)\rightarrow 2CrO_{4}^{2-}(aq.)+8H_{2}O(l)$

The coefficient of water is 8.

The normal boiling point of methanol is 64.7Â°c and the molar enthalpy of vaporization if 71.8 kj/mol. the value of Î´s when 2.1

kvasek [131]

The value or amount of heat that is needed in order to vaporize the given amount of methanol (CH3OH) can be calculated through the equation,
H = (n)(hf)

where H is the amount of heat
n is the given amount in mol, and
hf is the molar heat of vaporization

Substituting the known values,

H = (2.15 mol CH3OH)(71.8 kJ/mol)
H = 154.37 kJ

<em>ANSWER: 154.37 kJ</em>
