Answer:
If the hydronium concentration increases, the pH decreases, causing the solution to become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution.
Answer:
D. Chemoautotrophs
Explanation:
Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.
Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.
Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.
Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.
Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.
Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.
Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

The acronym that is commonly used to remember the elements of a valid and enforceable contract is COAL.
What is the COAL acronym?
- Any contract must contain four basic features in order to be valid.
- In other words, a real estate contract must include these important characteristics in order to be legally binding.
- The abbreviation COAL might help you remember the four important contract elements.
- Consideration is defined as a value exchange. The parties' values exchange could be equal, but it is not needed.
- A proposal must be made. The buyer typically makes the offer in real estate negotiations.
- In a real estate contract, the offeree, who could be the seller or bidder depending on whether there were any counter-offers, will do this.
- The goal of the real estate deal must be legitimate.
