Answer:
use the equation Mass= RFM*Moles
Explanation:
use your periodic table
and create a little table
Answer:
63.6 dm³
Explanation:
Volume of gas= no. of moles ×24dm³
Thus, volume of N₂O
= 2.65 × 24
= 63.6 dm³
Here are the choices:
Warm air rises while cold air falls.
The warmer air contains less water vapor per unit of volume.
The warmer air contains more water vapor per unit of volume.
Moist air has lower density than dry air does.
The best answer is: <em>The warmer air contains more water vapor per unit of volume.
</em>
Answer:
The answer is the B. Proteins
Explanation:
It is known that Ribosomes are the factory to synthesize proteins. This is their function. In cell zones where ribosomes are abundant, proteins are actively produced
Answer:
1) chemical property
2) physical property
3) chemical property
4) physical property
Explanation:
Physical properties:
Physical properties are those properties which can be measured without changing the composition of mater. We can observe the object and tell its physical properties like its texture, physical appearance, color, melting point, boiling point, odor, density etc.
Chemical properties:
Chemical properties involve chemical reaction or we can say that change is happen in mater during chemical reaction and the properties, we measured during this or as a result of this reaction is called chemical properties. Like flammability, toxicity, combustion, decomposition etc.
1) Water can split into hydrogen and oxygen
chemical property
2) water is liquid at room temperature
physical property
3) water react with certain metals
chemical property
4)The density of water is 1.0 g/cm³
physical property
