Cyclopropane and propylene isomers both have the formula c3h6. based on the molecular structures shown, which of these isomers w
Hoochie [10]

The measure of randomness or uncertainty  of the substance is known as the entropy of the substance.

Under the standard state, the entropy of one mole of substance is known as its standard molar entropy.

The structure of cyclopropane and propylene is shown in the attached image.

Since, the structure of propylene is an open chain structure thus, possessing high randomness. Whereas the structure of cyclopropane is ring (closed) structure and thus, not that much free to move and has less randomness.

Hence, the structure of propylene will have the higher standard molar entropy.

A hydrate of zinc nitrate has the formula Zn(NO3)2 . xH2O. If the mass of 1 mol of anhydrous zinc nitrate is 63.67% of the mass
weqwewe [10]

MM Zn(NO₃)₂ = 189.36 g/mol

mass 1 mol Zn(NO₃)₂ = 189.36 g

mass hydrate = 100 / 63.67 x 189.36 = 297.409 g

mass 1 mol hydrate = 297.409 g

MM hydrate = 297.409 g/mol

MM hydrate = MM Zn(NO₃)₂ + MM xH₂O

297.409 = 189.36 + x(18)

x = 6

How could you demonstrate boiling point?
EleoNora [17]

A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.

The solid anhydrous solid CoCl2 is blue in color. Because it readily absorbs water from the air, it is used as a humidity indica
MrRissso [65]

Answer:

CoCl_{2}.(H_{2}O)_{6} is formed and it has three unpaired electrons.

Explanation:

Blue CoCl_{2} reacts with water to produce pink colored CoCl_{2}.(H_{2}O)_{6} complex.

In this complex, Co^{2+} ion forms an octahedral complex with six H_{2}O ligands.

As H_{2}O is a weak field ligand therefore Co^{2+} ion remains in low spin state.

Hence electronic configuration of Co^{2+} ion in this octahedral geometry is t_{2g}^{5}e_{g}^{2} with total three unpaired electrons.
