Answer: Reaction 1 is non spontaneous.
Explanation:
According to Gibb's equation:

= Gibbs free energy
= enthalpy change
= entropy change
T = temperature in Kelvin
When
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
For the given reaction 1:

As for the reaction 1 , the value of Gibbs free energy is positive and thus the reaction 1 is non spontaneous.
<u>Given:</u>
Mass of calcium nitrate (Ca(NO3)2) = 96.1 g
<u>To determine:</u>
Theoretical yield of calcium phosphate, Ca3(PO4)2
<u>Explanation:</u>
Balanced Chemical reaction-
3Ca(NO3)2 + 2Na3PO4 → 6NaNO3 + Ca3(PO4)2
Based on the reaction stoichiometry:
3 moles of Ca(NO3)2 produces 1 mole of Ca3(PO4)2
Now,
Given mass of Ca(NO3)2 = 96.1 g
Molar mass of Ca(NO3)2 = 164 g/mol
# moles of ca(NO3)2 = 96.1/164 = 0.5859 moles
Therefore, # moles of Ca3(PO4)2 produced = 0.0589 * 1/3 = 0.0196 moles
Molar mass of Ca3(PO4)2 = 310 g/mol
Mass of Ca3(PO4)2 produced = 0.0196 * 310 = 6.076 g
Ans: Theoretical yield of Ca3(PO4)2 = 6.08 g
Answer:
The description is outlined in subsection downwards and according to the query given.
Explanation:
- Saponification seems to be a procedure that requires the conversion or transformation of fat, grease, or lipid by either the intervention of heating a mixture of aqueous alkali towards soap as well as an alcoholic. Soaps contain fatty acid salts, however, mono-fatty acids contain carbon atoms, such as sodium palmitate. Therefore, throughout the water, individuals were indeed soluble.
- However, on another hand, owing to large hydrocarbon strings, triglycerides do not partake in hydrogen bonding. Therefore in water, they aren't dissolved.
Answer:
B represents gas at room temperature and C represents hot gas.
Explanation:
- <em>As the temperature increases, the no. of particles that has higher energy increases.</em>
So, A represents the cold gas, because it has the lowest no. of particles that has high energy.
B represents the gas at room T because it has more no. of particles with higher energy.
C represents the hot gas, because it is the curve that has the highest no. of particles with high energy.
<em>B represents gas at room temperature and C represents hot gas.</em>
