Explanation:
Charles' law gives the relationship between the volume and the temperature of the gas. Mathematically,
Volume ∝ Temperature
i.e.
We have, V₁ = 1.6 L, T₁ = 278 K, T₂ = 253, V₂=?
So, the new volume is 1.45 L.

Answer:The correct answer is option C.
Explanation;
Water has unique property that is, it expands on freezing.Which is the reason for less density of ice than water. The cracking of the bottle was due to the expansion of water (present inside the bottle) on freezing.
Generally, density is inversely proportional to the volume of the substance.
As we know ,that water expands on freezing which means that volume increases. And with increase in volume of density decreases.
Hence, the correct answer is option C.
Each neutral carbon atom contains four valence electrons and may form up to four electron domains. Possible hybridizations include
, four electron domains, as in ethane
, three electron domains, as in ethene
, two electron domains, as in ethyne
Molecules of each of the three hybridization demonstrate spatial configurations that would maximizes the separation between the electron domains.
- Carbon atoms with a
- Carbon atoms with a
- Carbon atoms with a
Bond angles are characteristic of the spatial configuration of electron domains and identifies the hybridization of the central carbon atom.
Note that each hydrogen atom contains only one valence electron and would form only single bonds. It takes two valence electrons for oxygen atoms to achieve an octet such that each oxygen form only two bonds at a single time. Therefore given the fact that the carbon is bonded to both hydrogen and oxygen, only the following hybridizations are possible
