There are several types of keboard designs and research is ongoing to improve their efficiency e,g QWERTY, QWERTZ and AZERTY keyboards
<h3>Types of Keyboards</h3>
Bellow is an extended list of the various types of keyboards
- Qwerty Keyboards
- Wired Keyboards
- Numeric Keypads
- Ergonomic Keyboards
- Wireless Keyboards

Answer:
See explanation
Explanation:
When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.
When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.
Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.
The final temperature on the block is 25 degrees.
Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.
Data given;
- M1 = 3.33g
- T1 = 25 degrees
- M2 = 44g
- T2 = 25 degree
- C1 = 124.5 J mol K
- C2 = 0.89 J/g K
<h3>Heat Transfer</h3>
Applying the principles of heat transfer,
Heat loss = Heat gain
From the calculation above, the final temperature on the block is 25 degrees.
