Answer: hydrogen
All acids have the hydrogen ion in common
Explanation:
According to Arrhenius theory, an acid is a substance which dissociate in water to produce hydrogen ions, H+;
For example: HCl --> H+ + Cl-
while a base is a substance which gives hydroxide ions, OH-, in water
For example: NaOH(s) --> Na+(aq) + OH-(aq)
Thus, all acids have the hydrogen ion in common
Chemistry is the branch of science that deals with the identification of the substances of which matter is composed.
There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit.
The molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
M1V1 = M2V2
Where;
- M1 = molarity of a base
- M2 = molarity of acid
- V1 = volume of base
- V2 = volume of acid
M1 × 200 = 50 × 5
200M1 = 250
M1 = 250/200
M1 = 1.25M
Therefore, the molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.

Answer:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). ... Interactions also occur among the spheres; for example, a change in the atmosphere can cause a change in the hydrosphere, and vice versa.
