Answer:
Intermolecular forces: forces attracting one molecule to its neighbors.
Explanation:
Hello,
Bonds are formed when two molecules are interacting (crashing or attracting to each other) and they are allowed to get joined via their valence electrons since we're talking about bonds. Those forces are called intermolecular forces as long as the molecules have charges that could attract or repeal another molecule (neighbors), of course, as we're considering bonds, we talk about attractive forces, making the bonding to be effective.
Best regards.
When paper burns, it releases two distinct forms of energy
Thermal Energy
Light Energy
Thermal Energy is heat energy, heat energy is formed from the flame on the paper, in this scenario.
Light energy comes from the reaction of the paper, the flame.
In conclusion, both energy's form from the reaction of the paper, and the combustion in the air. Thus, heat and light.
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
