Answer:

Fungi are a food source for animals and humans. This point do not apply on fungi.

Explanation:

Roles of fungi:

Penicillin and Cephalosporins are the antibiotics made by fungi. They are natural sources of antibiotics.

Fungi are eaten by animals examples are mushroom, agaricus and some animals even eat poisonous mushrooms.

Fungi destroy by releasing chemicals into the rock and they get iron this way and then deeply burrow the rocks and harming them.

Fungi acts as a decomposer to nourish the soil and improves vegetation.

Many infections are caused by fungus like ringworm infection, candida and Athlete's food are some examples.

please help I don’t understand the difference between ammonium and ammonium ion. I possibly did 9.a) correct but part b is a bit

ozzi

You may find the electron diagram of ammonia and the ammonium ion in the attached picture.

Explanation:

Ammonia NH₃ have covalent bonds with the hydrogen atoms in which for each bond one electron comes from nitrogen atom (blue dot) and the other from the hydrogen atom (red dot). You may see that the nitrogen remains with the lone pair of electrons that does not participate in bonding.

Ammonia NH₃ have a basic character and is able to accept a proton H⁺ from an acid to form the ammonium ion NH₄⁺. The fourth bond formed its called a coordinative-covalent bond that is created only with the nitrogen lone pair of electrons (blue dots).

What are the spectator ions in this equation?

dangina [55]

The given question is incomplete. The complete question is :

What is the net ionic equation for the following reaction?

$H_2CrO_4+Ba(OH)_2$

Answer : The spectator ions are $Ba^{2+}$ and $CrO_4^{2-}$

Explanation:

Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

$2H^+(aq)+CrO_4^{2-}(aq)+Ba^{2+}(aq)+2OH^-(aq)\rightarrow Ba^{2+}(aq)++CrO_4^{2-}(aq)+H_2O(l)$

The ions which are present on both the sides of the equation are barium and chromate ions. and hence are not involved in net ionic equation.

Hence, the net ionic equation is $H^++OH^-\rightarrow H_2O$

Featured snippet from the web
A solution is made when one substance called the solute "dissolves" into another substance called the solvent. Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules.
