Explanation:
To mark the upper fixed point, the thermometer is placed in a hypsometer containing water as shown in the figure. The bulb of the thermometer should be outside the water. When the mercury level becomes stationary at a temperature of steam, the level is marked, which represents the upper fixed point of the thermometer.
Answer:
Buckminsterfullerence is called an allotrope of carbon because it was discovered during an experiment involving a cluster of beam which uses laser to vapourise a graphite rod in a helium atmosphere to produce carbon plasmas.a mass sectrometry evidence from the experiment showed that carbon molecules with C60 were forming with a spheroidal geometry.so therefore it was included as an allotrope of carbon.
7.) Yes, both are insects.
8.) Homologous since the organisms are closely related
Answer:
, The partial pressure of O2 is = 21 atm
Explanation:
The concept is the pressure exerted by each gas is independent of one another or in other words independent of the pressure exerted by all other gases present.
This means that total pressure is the sum of the individual pressure of each gas by dalton's law.
So, putting the given values we get
43 = P_O2 +15+7
P_O2 = 21 atm
Therefore, The partial pressure of O2 is = 21 atm
Answer:
x = 5 kg
Explanation:
Given data:
Number of bushel = 0.20
Mass of 0.20 bushel apples = 2 kg
Mass of 0.50 bushel apples = ?
Solution:
The given problem will solve by cross multiplication.
0.20/ 2.0 = 0.50 / x
x = 2/0.20 × 0.50
x = 10 × 0.50
x = 5 kg
