How many asymmetric centers are present in the open chain form of the aldohexose d-(-)-gulose?
a_sh-v [17]
Answer:
             FOUR <span>asymmetric centers are present in the open chain form of the Aldohexose d-(-)-Gulose.

Explanation:
                   Here the word Asymmetric center means those carbon atoms which contains atoms or group of atoms different from each other. All the four atoms or group of atoms attached to carbon atom are different and have different molecular masses. Such carbon atoms are also called as Chiral carbons. The structure of </span>d-(-)-Gulose is drawn below, and all Four Asymmetric centers are pointed by " * "

Answer:

1. The enthalpy change for the backward reaction is –20 KJmol¯¹

2. The forward reaction is endothermic.

3. The activation energy for the forward reaction is +70 KJmol¯¹.

Explanation:

Considering the diagram given above, the following data were obtained:

1. The enthalpy change for the forward reaction being is +20 KJmol¯¹ and so, the enthalpy change for the backward reaction is –20 KJmol¯¹

2. The heat energy of the product is higher than that of the reactant. Therefore, the forward reaction is endothermic.

3. Activation energy is the minimum energy needed to be overcome in order for the reaction to proceed to product. It can be obtained from the energy profile diagram by considering the energy between the reactants and the peak.

For the question given above, Activation energy = 20 + 50

Activation energy = +70 KJmol¯¹

How many grams of methane gas (CH4) need to be combusted to produce 12.5 L water vapor at 301 K and 1.1 atm? Show all of the wor
tangare [24]
Answer is: 4.45 grams of methane gas <span>need to be combusted</span>.
Balanced chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O.
Ideal gas law: p·V = n·R·T.<span>
p = 1.1 atm.
T = 301 K.
V(H</span>₂O) <span>= 12.5 L.
R = 0,08206 L·atm/mol·K.
</span>n(H₂O) = <span>1.1 atm · 12.5 L ÷ 0,08206 L·atm/mol·K · 301 K.
</span>n(H₂O) = 0.556 mol.
From chemical reaction: n(H₂O) : n(CH₄) = 2 : 1.
n(CH₄) = 0.556 mol ÷ 2 = 0.278 mol.
m(CH₄) = 0.278 mol · 16 g/mol.
m(CH₄) = 4.448 g.
