Reaction arrows are used to describe the state or progress of a reaction. 2.1 The Chemical Reaction Arrow. The chemical reaction arrow is one straight arrow pointing from reactant(s) to product(s) and by-products, sometimes along with side products. A → B. It is the most widely used arrow.

Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust

The C5 (C5) fraction is a co-product of naphtha cracking and is used as a raw material for synthetic rubber and petroleum resins.

Deuterium

Deuterium is frequently represented by the chemical symbol D. Since it is an isotope of hydrogen with mass number 2, it is also represented by 2. H. .

Unimolecular Elimination (E1) is a reaction in which the removal of an HX substituent results in the formation of a double bond. It is similar to a unimolecular nucleophilic substitution reaction (SN1) in various ways. One being the formation of a carbocation intermediate.

Aqueous (aq.): In the presence of water, often meaning water is the solvent. Aqueous NaCl. Anhydrous NaCl.

Hydrogen is the chemical element with the symbol H and atomic number 1. ... Since hydrogen readily forms covalent compounds with most nonmetallic elements, most of the hydrogen on Earth exists in molecular forms such as water or organic compounds.

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.

Kp is the equilibrium constant calculated from the partial pressures of a reaction equation. It is used to express the relationship between product pressures and reactant pressures. It is a unitless number, although it relates the pressures.

Hope this helps a bit?

If you were asked to go to the chemical storage area and retrieve a bottle of “sulfate,” could you do so? Explain. (Assume you h
Evgesh-ka [11]

IT IS NOT POSSIBLE TO RETRIEVE A BOTTLE OF SULFATE BECAUSE SULFATE DOES NOT EXIST AS A DISTINCT CHEMICAL COMPOUND.

Sulphate is a polyatomic ion. A polyatomic ions refers to group of atoms that carry charges. Sulfate carries a charge of +2. Sulfate is a very reactive ion, thus, it can not be found existing on its own, it is always found in combination with other elements, such elements include H2SO4 and CaSO4.

for any substance solid liquid or gas mass increases as volume increases because density represnets mass per volume
Llana [10]

Answer:

A) False

B) True

Explanation:

The question is incomplete. The complete question is as follows.

There are two statements. Identify which statement is true or false.

A) For any substance, solid, liquid or gas, mass increases as volume increases.  

B) Density represents mass per volume.

Statement A

  1. Mass is defined as the amount of matter in an object. Its fixed and can't be changed.  
  2. Volume on the other hand is the amount of space an object takes up.  

Since the amount of matter is fixed, an increase in volume doesn't cause an increase in mass. For example, a test tube, with a volume of 10ml, contains liquid fragrance. When heated, the fragrance vaporizes and fill the entire room, until you can smell it in every corner. Note that previously the fragrance of same mass was occupying a 10ml space in the test-tube. After heating, the same mass of fragrance occupied the entire room (volume increased but mass remained constant).

It happened because as the fragrance is heated, the space between molecules increases causing them to occupy more space BUT in the whole scenarios, the number of molecules stayed unaffected. <u>Hence statement A is false. </u>

Statement B

Density measures the compactness of the substance. It's defined as the amount of mass per unit volume. It increases as the atoms/molecules in a substance comes closer. Density of solids are greatest as the atoms/molecules are tightly packed together. It is least in gases as the molecules are far apart from each other. <u>Hence the statement is true. </u>
