The best symbolizes the hydrogen bonding between two water molecules is given in the diagram.
<h3 /><h3>What is hydrogen bonding?</h3>A hydrogen bond is an attraction between an electronegative atom carrying a single pair of electrons—the hydrogen bond acceptor—and a hydrogen atom that is covalently bonded to a more electronegative "donor" atom or group.
One definition of a polar covalent bond is one in which one atom has a stronger alternation for electron negativity difference between two bonds, the more polar the link.
Polar molecules like H2O have a mild partial negative charge in one area and a partial positive charge in another.

Answer:
Zero
Explanation:
The work done by a force on an object is given by:
where
F is the magnitude of the force
d is the displacement of the object
is the angle between the direction of the force and the displacement of the object
In this situation, the force is the force of gravity acting on the satellite. This force always points towards the centre of the trajectory, so it is always perpendicular to the direction of motion of the satellite (since the orbit is circular), so and
. Therefore, the work done by gravity is also zero.
Answer:
The developed pressure is 205.75 bar.
Explanation:
Given that,
Temperature of water =25°C = 273+25 = 298 K
Pressure = 1 bar
Increases temperature = 50°C = 273+50 = 323 K
Value of
Value of
Specific volume of liquid = 1.0030 cm³/g
We need to calculate the final pressure
Using formula for constant volume change
Put the value into the formula
Hence, The developed pressure is 205.75 bar.
