1.Chemical nomenclature, replete as it is withcompounds with complex names, is arepository for some very peculiar and sometimes startling names. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the consequence of simple juxtaposition. Some names derive legitimately from their chemical makeup, from the geographic region where they may be found, the plant or animal species from which they are isolated or the name of the discoverer.

How many moles of oxygen (O2) are present in 33. 6 L of the gas at 1 atm and 0°C? 1. 5 2 22. 4 32.
oee [108]

The number of moles of oxygen in the gas is 1.5 L.

The correct option is (A).

<h3>What are moles? </h3>

The mole is the International System of Units' foundation unit of material quantity.

Given,

The volume of gas is 33.6 L

Pressure is 1 atm.

Temperature is 0°C

Molar gas volume is 22.4 L

There is no temperature and pressure is 1 atm.

By formula of moles, volume is divided by molar mass

\bold{\dfrac{33.6}{22.4 } =1.5\; mole}

Thus, option A is correct. 1.5 L.

Answer:

17. D. Chemical change

18. C. Cell wall

19. D. To transfer matter and energy within and between organisms.

20. A. Transporting materials

21. C. Carbon dioxide

22. A. Cellular respiration

23. C. Produce food and give off oxygen

Explanation:

I have been able to supply the correct answers. The cell wall functions as a structure that provides structural support and protection to the cell. It is tough, flexible and at times rigid. In a chemical change, new materials with new properties are manufactured. So, the process of photosynthesis is a chemical change.

The endoplasmic reticulum actually transports material. It transports materials like protein and lipids made within the cell and sends it to where they are needed.

Carbon dioxide  is the the gas that animals give off and plants use it during photosynthesis. Cellular respiration involves the activities that result to the breaking down of food in order to release energy.
