True
Explanation:
The physical properties and the chemical reactivity of halogens are best investigated in several different compounds. Compounds of a substance gives us good knowledge about how they behave and exists in nature.
- Halogens are very reactive group of elements.
- Due to their high electronegativity, they are the most reactive on the periodic table.
- They tend to find one electron to complete their octet by all means.
- They favor reactions where they have easy access to electrons.
- When atoms combines, they have different chemical properties.
- When the molecules combine to form intermolecular bonds, it tells on their physical properties.
- The compounds of halogens is a very good way to investigate their chemical reactivity and physical properties.

The answer is A, when these particles are heated they tend to speed up.
Answer:
diplode-diplode interactions
Explanation:
Answer:By their movement, by their wastes, and by their metabolic.
Explanation:The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. This occurs as animals and plants consume nutrients found in soil, and these nutrients are then released back into the environment via death and decomposition.
Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
