Write the number of each atom in the chemical formulas for all of the possible combinations of positive and negative ions found

on the cards. You can use the cards to figure out the formula by making as many copies of the cards as necessary to get them to line up exactly equally.
Example:

Na__Cl___

The chemical formula is NaCl, so you would place a 1 in the box for both Na and Cl.

A chemical formula is obtained from the number of atoms in a compound.

Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.

For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

____ demonstrated that electrical stimulation of certain areas of the brain could be reinforcing.
stepladder [879]

Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.

<h3>Electrical brain stimulation</h3>

it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.

<h3>What is the purpose of brain electrical stimulation?</h3>
  • Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
  • Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.

Olegator [25]

Answer:

In case of Yucca plant and Yucca moth,they cannot survive without each other.Yucca moth larvae feed on seeds of Yucca plant and Yucca plant have a single pollinator i;e, Yucca moth. Yucca moth collects pollen from anther and fly to another flower and transfer that pollen to other flowers stigma. In this way they transfer the pollen , usually they make a hole in the ovary to lay eggs and directly transfer pollen to the inside of the stigma.

After laying eggs they mark it with some special kind of pheromone which alerts other moths not to lay egg inside the same flower or lay some eggs not much. So that they can be protected inside the flower and can be developed well.
