In this case, among the list of components given, the abiotic factors are water, rock, soil, and sun.
<h3>What is an abiotic factor?</h3>
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
Biotic and abiotic factors make up a community via interaction.
Biotic factors are considered living things (having "life") while abiotic factors are simply non-living things.
Hence, in this case, among the list of components given, the abiotic factors are water, rock, soil, sun

Answer:
For the formation of nitrogen dioxide, the reactants used are nitrogen monoxide and oxygen gas. 2 moles of nitrogen monoxide gas react with 1 mole of oxygen gas to produce 2 moles of nitrogen dioxide gas.
Explanation:
To balance this equation you would do whatever you did I TO one side to the other... so if there is 18 oxygen on the right side then there must be 18 on the left. So 18/2 equals 9... the. You equation will be balanced
Answer: b. accepts 
ions from acids
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions 
when dissolved in water and an acid is defined as a substance which donates hydronium ions 
in water.
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates ions and a base is defined as a substance which accepts ions.
Here water is donating ions, and thus act as acid and ammoia 
is accepting ions from water and thus is a base.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
Thus base is a substance which accepts ions from acids.
