Answer:
d. A water particle and an air particle
Explanation:
The force of gravity (F) between two objects of masses m1 and m2 and separated by a distance r is given as:
where G is the gravitational constant
This force is therefore, directly proportional to the masses and inversely related to the distance between them.
Based on the given options, since the masses of the water and air particles are very small (masses of earth, moon and sun is relatively huge), the gravitational force between them would be negligible and difficult to measure.
Hydrogen bonds are present in the following molecules: HF AND NH3
Dipole dipole inter molecular forces occurs the molecules of H2S AND H2.
Hydrogen bonding is an electrostatic attraction between two polar groups that occur when hydrogen atom covalently bound with highly electronegative atoms.
Well according to me Cesium releases enough energy that even a small piece blows up in water. Francium is below cesium on the table and would react more readily and violently.
Answer:
Increasing the speed of the particles
Explanation:
The energy absorbed in the phase B is used to increase the speed of the particles.
We can see a positive slope which shows that the temperature is increasing considerably with increasing time.
At this phase the reaction rate is become faster as the temperature change has a considerable effect on reaction rates.
Temperature is directly proportional to the average kinetic energy of reacting particles.
