उत्तर : 4. "it is either homogenous or heterogenous"
व्याख्या :

Answer: D) it is either homogenous or heterogenous Explanation: A mixture is the blending of two or more dissimilar substances.   Characteristics of a Mixture: 1. It has No formula. 2. It is an impure sustance 3. They can be mixed in any ratio. 4. The properties of the mixture are the properties of its constituents. 5. Constituents can e easily seperated by physical methods.eg: Heating, Drying, Crystallization, Distillation etc... 6. It is either homogenous or heterogenous.   A major characteristic of mixtures is that the materials do not chemically combine. Mixtures can be divided into those that are evenly distributed (homogeneous) and those that aren't (heterogeneous).

उत्तर : 3. "2"
व्याख्या :

Answer: C) 2 Explanation: Here the most stable carbocation is the option (2).   Carbocations are always hungry for electrons. The stability of carbocations increases from primary to secondary to tertiary. Here, option (c) shows the most stable carbocation because it can easily withdraw electrons from two other carbon atoms and the more electronegative oxygen atom.   Carbocation stability depends on hyperconjugation. The tertiary carbocation is stabilized by electron releasing inductive effect.

उत्तर : 4. "All the above"
व्याख्या :

Answer: D) All the above Explanation: Most of the emissions of greenhouse gases (GHG) come primarily from burning fossil fuels (coal, hydrocarbon gas liquids, natural gas, and petroleum) for energy use and the major greenhouse gas is of course carbon dioxide (CO2) which comes from burning fossil fuels and land-use change. But methane (CH4) and nitrous oxide (N2O), which mostly come from agriculture and waste, are also significant GHGs and shouldn't be discounted.

उत्तर : 2. "Stratosphere"
व्याख्या :

Answer: B) Stratosphere Explanation: The ozone layer is a region of Earth's Stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.   The Atmosphere is divided into 4 layers according to major changes in temperature. They are : 1. Troposphere, 2. Stratosphere, 3. Mesosphere  and 4. Thermosphere. The farther away from earth, the thinner the atmosphere gets.
