Which of the following lists describes characteristics of a base? (3 points)
mel-nik [20]

Answer:

slippery, high pH, and caustic (last option)

Explanation:

when we say base we should think soap. soap is slippery. Bases give OH- ion. when OH- is combined with H+ ion it will create water which raises the pH. Since base can dissolve fats, ex: using dish liquid to cut grease on pots and pans etc.. they are caustic. Biologically they can disrupt the cell memebrane making it caustic to cell tissue.

Predict and balance the following reaction:
balandron [24]

The prediction of the products and the balanced form of the above incomplete equation is as follows: Ag + Cu(NO3)2 → Cu + Ag(NO3)2 (option D).

<h3>How to balance a chemical reaction?</h3>

According to this question, silver reacts with copper nitrate to form products that were not stated.

However, this reaction is an example of a displacement reaction, hence, silver will displace or replace copper in the compound to form copper and silver nitrate as products. The reaction is given as follows:

Ag + Cu(NO3)2 → Cu + Ag(NO3)2

This chemical reaction is said to be balanced because the number of moles of each atoms on both sides of the equation is the same.
