Answer:
the gas particles strike the walls of the container more often
Explanation:
Following Boyle's law, if the amount of gas and the temperature remain constant, the product of the pressure for the volume remains constant, but when altering any of these conditions this value changes and is expressed through the equation:
<em> </em>
<em></em>
So, when the volume decreases, the distance that the particles have to travel is smaller and therefore more collisions between particles and between the walls occur per unit of time, that is, the system pressure increases.
Answer: option A. to decrease the solubility of the organic product in water
Explanation: sodium chloride solution act as a drying agent to remove water from an organic compound that is in solution. The salt water works to pull the water from the organic layer to the water layer,therby decreasing
Answer:
Both student have same percent error.
Explanation:
Given data:
Actual mass of object = 0.54 g
Measured value by one student = 0.59 g
Measured value by second student = 0.49 g
Percent error = ?
Solution:
Formula
Percent error = (measured value - actual value / actual value) × 100
Percent error of first student:
percent error = (0.59 g - 0.54 / 0.54 ) ×100
percent error = 9.3 %
Percent error of second student:
Percent error = (0.49 g - 0.54 / 0.54 ) ×100
Percent error = - 9.3 %
Both student have same percent error. The only difference is that first student measure the greater value then actual value and second student measure the less value then actual, however difference was same and gives same percent error.
Answer:
Third figure shows the best relationship.
(c) is correct option.
Explanation:
Given that,
The diagram best represents the relationship masses of subatomic particles.
We know that,
The mass of proton and neutron are same.
The mass of electron is less than mass of the proton and neutron.
We need to find the best represents the relationship masses of subatomic particles
According to figure,
Third figure shows the best represents the relationship masses of subatomic particles.
Hence, Third figure shows the best relationship.
(c) is correct option.
