Question

24) Why can’t we give Granny a cigarette when she is in the oxygen tent?

You’re not in her will yet. Patience.

Granny gets oxidized and oxygen gets reduced (fast)

She’s not interested in smoking tobacco….

Second hand smoke.

.

25) How do you make a glass:

Rapidly cool a melt

Slowly cool a melt

Dissolve a salt

Add acid to base

.

26) Kinetics describes?

Whether or not something can happen (is favorable)

How fast something happens

The mechanism by which something happens

The basis for Scientology.

Please answer all of them without guessing!!! Thanks

Explanation / Answer

24. The second option basically because the other three are reasons too ilogic, because you don't have enough information to say that. However, the chemical explanation would be that as your granny is in the oxygen tent, is she smokes a cigarrete there, the oxygen of the tent will be reduced and she'll be out of oxygen. That's why.

25. There are two methods for making glass. One of them involves dissolving salts, so this is the correct option. And explanation would be this:

Obtain silica sand. Also called quartz sand, silica sand is the primary ingredient in making glass. Glass without iron impurities is sought for clear glass pieces, as the iron will cause the glass to appear greenish when present.

Add sodium carbonate and calcium oxide to the sand. Sodium carbonate (commonly called washing soda) lowers the temperature necessary to make glass commercially. However, it permits water to pass through the glass, so calcium oxide, or lime, is added to negate this property. Oxides of magnesium and/or aluminum may also be added to make the glass more durable. Generally, these additives take up no more than 26 to 30 percent of the glass mixture.

These are the first two steps, and the second involves the dissolution of salt.

26. Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction.

Chemical kinetics deals with the experimental determination of reaction rates from which rate laws and rate constants are derived.

the free energy change (G) of a reaction determines whether a chemical change will take place, but kinetics describes how fast the reaction is. A reaction can be very exothermic and have a very positive entropy change but will not happen in practice if the reaction is too slow.

Therefore, option B is the correct option.
