The description which accurately represents a water molecule is slightly negative oxygen pole, slightly positive hydrogen poles.
Water is a polar molecule. This means that the molecule has a dipole moment.
The polarity of water arises from the difference in electronegativity between hydrogen and oxygen.
Hence, in water molecule, oxygen is slightly negative and hydrogen is slightly positive thereby resulting in a dipole.

Answer:
A car stopped at the top of a hill
Explanation:
Potential energy is the energy that is stored in an object due to its position relative to some zero position.
therefore, the answer is the first option
=> A car stopped at the top of a hill
hope this helps and is right :)
First we must find the relative formula mass of NH3:
14+(1x3) = 17
Now we use the formula moles(n)= mass(g)/Mr
From substitution we get 34.0/17 = 2
The answer is 2M (M for Moles)
Answer:
The rate of disappearance of 
is 0.0766 M/s.
Explanation:
Rate of the reaction = R
![R=-\frac{1}{1}\frac{d[C_2H_4]}{dt}=-\frac{1}{3}\frac{d[O_2]}{dt}](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BC_2H_4%5D%7D%7Bdt%7D%3D-%5Cfrac%7B1%7D%7B3%7D%5Cfrac%7Bd%5BO_2%5D%7D%7Bdt%7D)
[te]R=\frac{1}{2}\frac{d[CO_2]}{dt}=\frac{1}{2}\frac{d[H_2O]}{dt}[/tex]
Rate of disappearance of 
=0.23 M/s
Rate of disappearance of 
R =0.07666 M/s
Rate of disappearance of 
![\frac{d[C_2H_4]}{dt}=1\times 0.23 m/s=0.0766 M/s](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BC_2H_4%5D%7D%7Bdt%7D%3D1%5Ctimes%200.23%20m%2Fs%3D0.0766%20M%2Fs)
The rate of disappearance of is 0.0766 M/s.
