5 0

Answer:

There would be 25 moles

True or false: chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals
wel

Answer:

False

Explanation:

The octet rule forms the basis for chemical reactions. The octet rule states that; an atom is only stable when it has eight electrons around its outermost shell.

This implies that the driving force behind chemical reaction is the attainment of an octet structure(eight electrons in the outermost shell of each of the bonding atoms).

An atom that has only six electrons in its outermost shell is not yet stable according to the demand of the octet rule. Hence, the statement "chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals" is false.

Anastaziya [24]

Answer:

Compound

Explanation:

The given specie is a compound.

  • The properties of a compound are distinct and different from those of the individual elements that are combined in its make-up.
  • For this given specie, the elements are carbon, hydrogen and oxygen.
  • So, this is a compound.

Elements are distinct substances that cannot be split - up into simpler substances. Such substances consist of only one kind of atom

PLEASE HELP MEEE I WILL MARK BRAINLIST FOR THIS ITS SUPER SIMPLE....BUT U MUST TYPE EVERYTHING needed ASAP
Ilia_Sergeevich [38]

Answer:

Because when they brought the cows back the Autumn Buttercup began to thrive. They took the cows out of the pasture thinking that the Autumn Buttercup would grow better. They noticed that the Autumn Buttercup was thriving in a field nearby where there were cows grazing.

a.) When the cows ate the grass in the fields, it made the grass shorter that the mice couldn't live there and be safe from their predators.

b.) When the cows walk on the soggy ground it pushes up the soil on the sides of the cow print where the buttercup like to grow and not directly in the soggy soil.

Nature has been developing its habitats for thousands and thousands of years. In time there is a balance where there aren't too many plants and animals, but enough food for each. When there is a change in any habitat and something is taken out or introduces, then it changes the population of different species where it may deplet one type of species and let another type of species overpopulate. It can cause species to extinct. It will take nature hundredsof years to find balance again.
