chemical, is the answer your looking for
Helium is found in the 1st period of the periodic table. It also is part of the noble gases group in the last column (18th) of the table.
Answer:
Sodium nitrate and CH4
Explanation:
Acids have an "H" at the start and bases have a hydroxide (OH)
Answer:
It has a different value at different temperatures.
Explanation:
For any system in equilibrium, the molar concentration of all the species on the right hand side are related to the molar concentrations of those at the left side by a constant known as the equilibrium constant.
The equilibrium is a constant at a given temperature as it is temperature dependent.
A change in temperature of an equilibrium system shifts the system to a new equilibrium point. A rise in temperature actually shifts equilibrium position to the direction that absorbs heat and vice versa.
The shift in equilibrium as a result of temperature change is actually a change in the value of the equilibrium constant. Equilibrium constant is represented as ![K_{eq}](https://tex.z-dn.net/?f=K_%7Beq%7D)
The derivation of the equilibrium constant is based on the Law of Mass Action which states: the rate of a chemical reaction is proportional to the product of the concentrations of the reacting substances.
<span>The best answer among
the choices is the first option. The chemical property of soda is that it is a
highly basic substance. It's chemical name is sodium carbonate. It is more
basic than sodium bicarbonate. Adding soda ash in a solution would increase the
pH of the solution.</span>
