Answer:
It doesn't matter which chloride
Explanation:
Because Carboxylic acids reacts with any of these inorganic chlorides such as PCl3, PCl5 and SOCl2 to form acid chloride as the major product, then the acid chloride further reacts to form acid anhydride
Answer : The new volume of was, 5.17 L
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles of gas.
Mathematically,
![\frac{V_1}{T_1}=\frac{V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BT_1%7D%3D%5Cfrac%7BV_2%7D%7BT_2%7D)
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
![V_1=5.00L\\T_1=25^oC=(25+273)K=298K\\V_2=?\\T_2=35^oC=(35+273)K=308K](https://tex.z-dn.net/?f=V_1%3D5.00L%5C%5CT_1%3D25%5EoC%3D%2825%2B273%29K%3D298K%5C%5CV_2%3D%3F%5C%5CT_2%3D35%5EoC%3D%2835%2B273%29K%3D308K)
Putting values in above equation, we get:
![\frac{5.00L}{298K}=\frac{V_2}{308K}\\\\V_2=5.17L](https://tex.z-dn.net/?f=%5Cfrac%7B5.00L%7D%7B298K%7D%3D%5Cfrac%7BV_2%7D%7B308K%7D%5C%5C%5C%5CV_2%3D5.17L)
Therefore, the new volume of was, 5.17 L
Answer:
ΔH > O and ΔH > TΔS
Explanation:
When a reaction is non-spontaneous even though the standard entropy change of the reaction is large and positive the reason is the reaction is highly endothermic and dominates the term TΔS in the standard Gibbs free energy expression:
ΔG = ΔH-TΔS
Remember that for an endothermic reaction to be spontaneous ΔG < 0 and this can occur only if the term TΔS is greater than ΔH. This is not the case for quartz which requires a good quantity of energy to overcome its crystaline 3D lattice in which the oxygen are shared between 2 silicon atoms.
