Answer:
For A = 733.2 torr
For B = 740.1 torr
Explanation:
Given data:
For A
Height = 15.4 mm
Pressure of atmosphere = 0.985 atm ( 0.985 ×760 = 748.6 mmHg)
Pressure of gas = ?
For B
Height = 12.3 mm
Pressure of atmosphere = 0.99 atm ( 0.99×760 = 752.4 mmHg)
Pressure of gas = ?
Solution:
For A
P( gas) = P (atmosphere) - 15.4 mmHg
P( gas) = 748.6 mmHg - 15.4 mmHg
P( gas) = 733.2 mmHg or 733.2 torr
For B
P( gas) = P (atmosphere) - 12.3 mmHg
P( gas) = 752.4 mmHg - 12.3 mmHg
P( gas) = 740.1 mmHg
or
740.1 torr
Answer:
0.595 ml
Explanation:
Mass=Volume*Denisty. Substituting what we know, 6.25=V*10.5. Solving for volume, you will get 0.595 ml.
Answer:
D.- Using a sterile liquid and eliminating exposure to microorganisms.
Explanation:
Remember that Redi´s experiment is going to be with different jars cover the top. In this case, if the liquid is sterile that means any living thing is present there. so if by passing the time, there are no microorganisms, this is going to be the results that the spontaneous generation does not exist. From a non living liquid there can not produce a living thing.
Answer:
6080 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of car = 800 Kg
Acceleration (a) of car = 7.6 m/s²
Force (F) =?
The force experienced by the car can be obtained as illustrated below:
Force (F) = mass (m) × acceleration (a)
F = m × a
F = 800 × 7.6
F = 6080 N
Thus, the experience a force of 6080 N
Explanation:
Method of prepration of sodium thiosulphate - definition
In the laboratory, this salt can be prepared by heating an aqueous solution of sodium sulphite with sulphur or by boiling aqueous NaOH and sulfur according to this equation:
