I hope this helps in some way. I forgot to mention that the question states they want to find THE NUMBER OF MOLES for H2O. Yherefore, you would want mol of H2O on top.

Define the following terms:
Marrrta [24]

Answer:

a)An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur eg Melting of ice, Evaporating liquid water

   b)An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light.eg a spark, flame, or flash), electricity , a battery), or sound , explosion heard when burning hydrogen).

c)By definition an exothermic reaction produces heat as part of it’s process. The heat generated just by being alive is an exothermic process as well. And as such we become aware of when we feel “too cold” or “too hot” and try to either adjust to the conditions we are in, or minimize them, if possible. It is not merely odd, but contrary to intelligent living, that we choose to increase our discomfort and also risk our health by intentionally increasing not only the exothermic reactions we use but also maximize them to our own detriment. In short, the increased use of inefficient exothermic reactions while inexpensive in current evaluations of financial cost are extremely expensive in terms of it’s effect upon living things, including ourselves. It is as though we are choosing our homes to not only be next to a furnace, but as close as possible to the process.

What is the suffix for -<br>✯ Alcohols<br>✯ Ketones<br>✯ Halogens<br><br>thankyou ~​
antoniya [11.8K]

Answer:

ane, al, keto

ol, al, keto

ol, al, one

ol, ane, one.

Explanation:

The suffix –ol is used in organic chemistry principally to form names of organic compounds containing the hydroxyl (–OH) group, mainly alcohols (also phenol). The suffix was extracted from the word alcohol. The suffix also appears in some trivial names with reference to oils (from Latin oleum, oil).

Functional group is a ketone, therefore suffix = -one

Hydrocarbon structure is an alkane therefore -ane

The longest continuous chain is C5 therefore root = pent

The first point of difference rule requires numbering from the left as drawn to make the ketone group locant 2-

pentan-2-one or 2-pentanone

CH3CH2CH2C(=O)CH3
