<span>The
bent geometry of the water molecule gives a slight overall negative
charge to the oxygen side of the molecule and a slight overall positive
charge to the hydrogen side of the molecule. This slight separation of
charges gives the entire molecule an electrical polarity, so water
molecules are dipolar.</span>
Answer: 
Explanation:
Given
Mass of iron piece is 
Heat absorbed 
Temperature changes from 
i.e.
Heat absorbed is given by ![Q=mc\Delta T\quad [c=\text{specific heat of material}]](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T%5Cquad%20%5Bc%3D%5Ctext%7Bspecific%20heat%20of%20material%7D%5D)
Insert the values
Thus, the specific heat of iron is
Answer:
If a metal is less reactive than carbon, it can be extracted from its oxide by heating with carbon. The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal.
Explanation:
Answer:
B.
Explanation:
when you use punnett squares, you cross the different genes with themselves. if T is in the first box on both sides, the genome will be TT. if the box lines up to tt, it will be tt. the boxes on the left use the genes' first letter and the boxes on the right use the second letter.
