Answer:
Which statement is true about the particles of a solid when the solid changes into a liquid? (5 points)
a. They stop vibrating.
Selected: b. Their kinetic energy increases. This answer is correct.
c. They move closer to each other.
d. The attractive force between them increases.
Explanation: when a solid turns to a liquid it means it was melted and it needs to be heated to melt meaning the kinetic energy increases because the solid was heated up. Also this was on my test and i got it right so yeah.
Answer:43800 mins
Explanation:
Each hour is equal to 60 mins so multiply it with the number of hours in a month 24x30=480 then multiply it by 60 which is equal to the answer
The answer is D. Ammonia is a weak electrolyte and a weak base. Ammonia produces ions when dissolving but remains predominantly as molecules that are not ionized. This is what makes it a weak electrolyte. Ammonia also does not fully ionize in a solution. This is what makes is a weak base.
The number of mole of the gas present in the sample which occupies a volume of 350 mL at 25 °C and 1 atm is 0.0143 mole
From the question given above, the following data were obtained:
Volume (V) = 350 mL = 350 / 1000 = 0.35 L
Temperature (T) = 25 °C = 25 + 273 = 298 K
Pressure (P) = 1 atm
Gas constant (R) = 0.0821 atm.L/Kmol
<h3>Number of mole (n) =? </h3>
With the application of the ideal gas equation, the number of mole of the gas present in the sample can be obtained as follow:
<h3>PV = nRT </h3>
1 × 0.35 = n × 0.0821 × 298
0.35 = n × 24.4658
Divide both side by 24.4658
n = 0.35 / 24.4658
<h3>n = 0.0143 mole </h3>
Therefore, the number of mole of the gas present in the sample is 0.0143 mole
