Answer:
Dinitrogen trioxide.
Explanation:
The correct name for the compound
is dinitrogen trioxide. The compound
also happens to be a <em>covalent compound</em>, and the nomenclature of covalent compounds involves the usage of numerical prefixes such as <em>"mono-"</em> and <em>"tri-"</em>.
Since there are two nitrogen atoms in the compound
, we can use the numerical prefix "di-", meaning two, to signify that.
Since there are three oxygen atoms in the compound
, we can use the numerical prefix "tri-", meaning three, to signify that.
Answer: I disagree. Elements form all pure substances, but some pure substances include elements bonded together to form molecules and compounds.
Explanation:
Pure substances are those that have a uniform and constant (invariable) composition.
That condition is met by both elements and compounds.
Elements are pure substances of one only kind of atoms. For example, gold, oxygen, sodium, hydrogen, are pure substances that arer elements. There are 118 elements known and they are all listed in the periodic table.
Compounds are pure substances formed by two or more different kind of atoms. Water (H₂O), table salt (NaCl), and ethanol (CH₃-CH₂OH), are examples of pure substances that are compounds. There are pratically infinite different compounds.
In conclusion, compounds are also pure substances, since every sample of a given compound has always the same kind of elements bonded in the same way.
Answer:
The answer is: the body contains chemicals called buffers that resist changes in pH
When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.

it just be like that sometimes my dude</h2>
What causes deep, cold currents to form in the oceans near the poles? The sinking of dense, cold water paired with high salinity.
Explanation:
Dissolve 93.52g of NaCl in about 400mL of distilled water, then add more water until final volume is 800mL. If starting with a solution or liquid reagent: When diluting more concentrated solutions, decide what volume(V2) and molarity (M2) the final soluble should be.
