Which of the following are weak electrolytes in aqueous solutions? Select ALL that apply.

Mandarinka [93]

Answer:

Weak electrolytes are

HgCl2 and NH₃

Explanation:

Electrolytes are compounds that conduct electricity while in molten or aqueous form.
Electrolytes may therefore be decomposed by passing electric current through them.

They may be either strong or weak electrolytes.

Strong electrolytes are those that ionize completely to form mobile ions while weak electrolytes ionize partially to generate ions.

Examples of weak electrolytes are HgCl2, NH₃
Examples of strong electrolytes are LiOH, HClO₄, and HI.

Scientist can use trees to look at climates of the past. How? What information can they gather and how do they gather it? Explai

andrezito [222]

Explanation:

Scientist use trees a whole lot to look at climate of the past by examining tree rings.

These are layers of cambium in each successive years formed. They have an annual growth pattern and are known as tree rings.

Tree rings can be used to decipher the age of a tree.

These three rings can be used to interpret climatic patterns.
During a wet climate, the tree rings are more robust and bigger.
In a dry climate, the rings are thinner.
These alternating patterns can be used to decipher the climatic signatures in a tree.
Sometimes, it is possible to evaluate some certain isotopes that are useful in climatic studies.
