Answer:

b) water molecule has a bent shape

Explanation:

In the context of chemical bonds, polarity refers to the separation of charges i.e. the distribution of electrons between the atoms constituting the bond. This charge separation creates a dipole.

Similarly polar molecules are made of polar bonds in which the bond dipoles add up such that there is a net dipole moment.

In water(H2O), the central O atom is more electronegative than H which creates a dipole directed towards the O atom. In addition, due bent shape of H2O the dipole moments add up (instead of cancelling out if it were linear) resulting in a net dipole which makes water polar.

What is the kinetic energy of 3500 kg bus that is moving at 25 m/s
Bond [772]

Answer:

<h2>1093750 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

v is the velocity

m is the mass

From the question we have

k =  \frac{1}{2}  \times 3500 \times  {25}^{2}  \\  = 1750 \times 625 \\  = 1093750 \:  \:  \:  \:  \:

We have the final answer as

<h3>1,093,750 J</h3>

Hope this helps you
