Write a net ionic equation for the reaction that occurs when excess hydrochloric acid (aq) and potassium sulfite (aq) are combin
Ket [755]

<u>Answer:</u> The net ionic equation for the given reaction is 2H^+(aq.)+SO_3^{2-}(aq.)\rightarrow H_2O(l)+SO_2(g)

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are the ions which do not get involved in a chemical equation. It is also defined as the ions that are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of hydrochloric acid and potassium sulfite is given as:

2HCl(aq.)+K_2SO_3(aq.)\rightarrow 2KCl(aq.)+SO_2(g)+H_2O(l)

Ionic form of the above equation follows:

2H^+(aq.)+2Cl^-(aq.)+2K^+(aq.)+SO_3^{2-}(aq.)\rightarrow 2K^+(aq.)+2Cl^-(aq.)+SO_2(g)+H_2O(l)

As, potassium and chloride ions are present on both the sides of the reaction, thus, it will not be present in the net ionic equation.

The net ionic equation for the above reaction follows:

2H^+(aq.)+SO_3^{2-}(aq.)\rightarrow SO_2(g)+H_2O(l)

Hence, the net ionic equation for the given reaction is written above.

ankoles [38]
It will sink below the surface. Since dish soap is a surfactant, it will alter the water's surface tension. Lowering the surface tension, the water will no longer be able to support the mass of the twig.

Which of the following threats to biodiversity is a result of cutting down forests? (4 points)
Maslowich

Answer:

Explanation:

When I was growing up, one of the most popular cartoons was a little possum whose name was Pogo. He often said

“We have met the enemy and he is us.”

It is something Pogo said more than once. We are the problem with biodiversity being threatened.

We clear land for agriculture, not only in Canada and the United States, but in places like Brazil where it matters what is done to the environment. Those trees are the planet's lungs. Whole environmental groups are devoted to stopping the harvesting of trees that are hundreds of years old.

Our oceans have become cesspools of plastic.

Our rivers have become dumping grounds for all kinds of pollutants like paint and car tires to name just a couple.

Our landscape has been cluttered by billboards advertising things that are hundreds of miles away.

There's mining, oil, and other industries that make Mother Nature shudder every time they come near her.
