Answer:
Yes but there are more hydrogen ions than hydroxide ions.
An acidic solution contains a large concentration of hydronium ions than hydroxide ions. Yes, an acidic solution contains hydroxide ions.
What are hydroxide ions?Hydroxide ions are produced from the ionization of water molecules carrying the positive charge on hydrogen.
A solution contains both the hydroxide OH⁻ and hydronium ions H⁺.
In order to make a solution acidic, a solution must contain more hydronium ions compared to hydroxide ions.
Yes, an acidic solution contains hydroxide ions.

( 15 points to whoever replies quickest no links pls ) a farmer has used a fertiliser containing ammonium nitrate, potassium nitrate and ammonium sulphate on his fields but some may have leached into a nearby river. If a sample of river water was tested, what colour would the flame be if there was fertiliser contamination
If water of the river was tested there would be orange color flame.
What is fertilizer?Millions of tons of air, natural gas, and mined ores are transformed into plant nutrition products based on the three crucial nutrients nitrogen, phosphorus, and potassium by the fertilizer industry.
The process begins by combining nitrogen from the air with hydrogen from natural gas at high temperature and pressure to produce ammonia, which is then used to make nitrogen-based fertilizers, the largest product category. Natural gas is used as a raw material for about 60% of the time, while the remaining 40% is used to power the synthesis process.
The nitric acid created from the ammonia is combined with it to create nitrate fertilizers like ammonium nitrate (AN). Urea can also be made by combining ammonia with liquid carbon dioxide. To create UAN (urea ammonium nitrate) solution, both of these products can be combined with water.
Therefore, If water of the river was tested there would be orange color flame.

some students observe four different lab investigations. The students record their observations in a table.
Investigation
Observations
1
A beaker of water is
heated on a hot plate. Bubbles form in
the water, and steam is given off.
2
Oil is added to a beaker of water. Oil forms a layer on top
of the water
3
Sand and iron filings are mixed in a beaker. A magnet is
then used to separate the iron filings from the sand.
4
A piece of chalk is placed in a beaker of vinegar Bubbles
form as a gas is given off.
Which investigation most likely involved a chemical reaction?
Answer:
Number 4 is an example of a chemical reaction
Explanation:
heThe chalk is reacting with the vingear which is creating a new substance. The new substance is the gas that the reaction gives off.

How does resource extraction affect local and national economies?
Answer:
The direct channels by which extraction can affect the economy are of particular interest. The development of mines or oil and gas fields can result in significant shocks to a regional economy, generating jobs and drawing in capital from other regions and countries.

What happens to salt water and fresh water when you try to mix them.
Answer:
the lighter fresh water rises up and over the salt water
Explanation:
this is because the salt water is denser
Answer:
When trying to mix fresh/salt water it leads to variable and dynamic chemical conditions, especially salinity because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.
