Concept explainers
Interpretation:
The nitrogen formed during a lightning strike reacts with oxygen gas to form nitrogen monoxide which further reacts with ozone gas to form a nitrogen dioxide gas and oxygen gas. A balanced overall equation for this process is to be written.
Concept introduction:
Some reactions occur in a sequence. In such type of reactions, a product of one reaction acts as a reactant for the next reaction. Hence, some substances are common to both reactions. For the stoichiometric purposes, the substance that is formed as a product and act as a reactant in the next reaction sequence is eliminated in an overall/net equation.
Following are the steps to write the overall equation for the reactions that take place in a sequence,
Step 1: Write the sequence of the balanced equations.
Step 2: Cancel the common substance(s) by adjusting the equations arithmetically.
Step 3: Obtain the overall balanced equation by the addition of the adjusted equations together.

- e. If (3R,4R)-3,4-dichloro-2,5-dimethylhexane and (3R,4S)-3,4-dichloro-2,5-dimethylhexane are in a solution at the same concentration, would this solution be expected to rotate plane polarized light (that is, be optically active)? Please provide your reasoning for your answer. [If you read this problem carefully, you will not need to draw out the structures to arrive at your answer...]arrow_forward1. How many neighbors does the proton that produces the multiplet below have? 2. 3. اللـ Draw a partial structure from the multiplet below.

Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forward
