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.
Choloroplasts are unique to plant cells.
They are used to absorb light energy, which animals don’t.
Therefore plants contain chloroplasts and animals don’t.
Answer:
If the temperature increases the molecular movement as well, and if it increases the same it will happen with the molecular movement.
Pressure, volume and temperature are three factors that are closely related since they increase the temperature, the pressure usually decreases due to the dispersion of the molecules that can be generated, so the volume also increases.
If the temperature drops, the material becomes denser, its molecules do not collide with each other, their volume and pressure increases.
Explanation:
The pressure is related to the molecular density and the movement that these molecules have.
The movement is regulated by temperature, since if it increases, the friction and collision of the molecules also.
On the other hand, the higher the volume, the less pressure there will be on the molecules, since they are more dispersed among themselves.
(in the opposite case that the volume decreases, the pressure increases)
Answer:
Explanation:
First, calculate the molar mass of NH4SO2. The molar mass can determine the number of moles. Then use Avogadro's number to calculate the number of molecules.
Key Steps:
Step 1. Calculate the molar mass of your compound
Step 2. Divide 2.3 grams by the molar mass of NH4SO2, this gives us moles
Step 3. Multiply by Avogadro's number (6.02x10^23) this gives you molecules.
The answer should be chloride and sodium
