Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl)
Bitter taste, high pH, and caustic Bitter are the characteristics of base.
<h3>What are the characteristics of base?</h3>
Bases have bitter taste, soapy feel, turn red litmus paper blue. Bases are substances that contain metal oxides or hydroxides. Its pH is higher than 7 up to 14.
So we can conclude that bitter taste, high pH, and caustic Bitter are the characteristics of base.

Answer:
<u>because of the process of refraction of light.</u>
Explanation:
Note, the term refraction refers to the process which results in the <em>bending of light </em>as it passes through a medium. This bending of light can make objects become magnified (or larger), or even smaller.
In this scenario, as the light passes slowly through water it affects how we perceive the objects (the words on the paper) behind the jar (more likely a glass jar). In other words, the light combined with the water refracts (changes direction of) the lights our eyes can see, making the letters seem to change size.
Answer:

Explanation:
Hello there!
In this case, for this general calorimetry problem, it turns out possible for us to calculate the required heat by using the general heat equation in terms of the mass, specific heat and temperature change:

Thus, by plugging in the mass, the initial and final temperatures and the specific heat of ice, 2.05 in SI units, we obtain:
