Answer:
CH
Explanation:
92.26% = 92.26 g
7.74% = 7.74 g
carbon is 92.26 x 1 mole/12.011 = 7.68
hydrogen is 7.74 x 1 mole/1.008 = 7.68
carbon 7.68 ÷ hydrogen 7.68 = 1
so 1 is your subscript for both carbon and hydrogen
Answer:
In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.
Explanation:
Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in.
Answer:
Sound waves required a medium.
Explanation:
In space, there is only vacuum hence no any medium for sound wave travel.
Since sound waves are mechanical waves, they require a material medium such as air, hence no sound transmission.
Answer:
Explanation:
The steps of the Ostwald process:
Combinning the equations:
+
+
=
Simplifying:
The overall reaction is endothermic becuase the formation of new chemical bonds requires energy consumption.
Answer:
- Both accurate and precise.
Explanation:
The experimental data is characterized as the data that is generated through a specific test or measurement with the purpose of analysis or evaluation. As per the question, the minuteness of the given data(29.27, 29.32, and 29. 27)most aptly describes that the experimental data collected by the student possesses 'accuracy and precision' apt and specific. It would yield the most worthy and reliable conclusion.
