⇒ Acids taste <em>sour, react with metals, react with carbonates, and turn blue litmus paper red</em>. Bases <em>taste bitter, feel slippery, do not react with carbonates and turn red litmus paper blue</em>.
The study of acids and bases is crucial to chemistry. The Lewis acid/base motif, which broadens the concept of an acid and base beyond H+ and OH- ions, is one of the most relevant theories.
Acids are ionic compounds, which means they have a positive or negative charge. In water, these ionic compounds separate to create hydrogen ions, or H+.
The quantity of H+ ions in the solution determines how strong an acid is. Acid is stronger the more H+ there is. Bases are ionic substances that separate in water to produce the negatively charged hydroxide ion (OH-). The quantity of Hydroxide ions in a base determines its strength (OH-). The strength of the base increases with OH- ion concentration.

Answer:
1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.
2. The image cannot be projected onto a screen also.
3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.
Thanks!
Answer:
Explanation:
From the question we are told that:
Radius r=13
Coefficient of static friction \mu=0.67
Given the Centripetal concept
Generally the equation for Velocity v is mathematically given by
The value of the minimum speed (in m/s) for the cyclist to perform the stunt is Given as
The correct answer for above statement is:
A. Heat energy is released by the substance.
Explanation:
The reverse of deposition is sublimation and therefore generally deposition is termed desublimation. One example of deposition is that the method by that, in sub-freezing air, water vapor changes on to ice while not initial changing into a liquid.It is a process of releasing energy.
