Neither F2 nor Br2 are polar because they are nonpolar. It is a good rule of thumb to know that any diatomic molecules like F2 or Br2 are always going to be nonpolar. Another way to determine this is to use the acronym SNAP ( symmetrical=nonpolar, asymmetrical=polar). Since both F2 and Br2 are symmetrical molecules, they must be nonpolar.
I hope this helps.
There is one simple way to determine between solids, liquids, and gases. Are you able to move the substance? And if you are, how does it move? If it takes on the shape of its new container, it is a liquid. For example, if you pour water from a cup into a bowl, it will fill the bowl, not stay in the same shape as it was in the cup. However, if you put a marble in a cup and then pour the marble into the bowl, it will remain the same shape, and is therefore a solid. If you move a gas into a container, and the container is not sealed, it will not remain in the same shape.
Hi! To find the amount of grams in 2.34 moles of cobalt, you must use the following equation:
2.34 mol Co * (58.93 g Co)/(1 mol Co)
The answer would therefore be 137.9 grams
The most used temperature scale by scientists is the Kelvin scale.
Answer:Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds. Elements cannot be divided into smaller units without large amounts of energy.
