Which of the following materials is not considered to be a semiconductor? germanium tin silicon aluminum

Answers

Tin and Aluminum are not considered as semiconductors but rather conductors themselves because they are metals. Semiconductors are in general elements from column IV or or compounds of columns III and V of the periodic table.

Germanium and silicon are semiconductors because they are metalloids.
Aluminium is not considered to be a semiconductor.

Identify the following as True or False? 1. The limiting reactant is the reactant that is completely consumed in a chemical reaction.
2. The reactant in excess is any reactant that occurs in a quantity greater than that is required to completely react with the limiting reactant.
3. The amount of product can be calculated based on the amount of limiting reactant.

Answers

Answer :

(1) The limiting reactant is the reactant that is completely consumed in a chemical reaction.  → True

(2) The reactant in excess is any reactant that occurs in a quantity greater than that is required to completely react with the limiting reactant.  → True

(3) The amount of product can be calculated based on the amount of limiting reactant. → True

Explanation :

Excess reagent : It is defined as the reactants not completely used up in the reaction.  The given moles are more than the required moles.

Limiting reagent : It is defined as the reactants completely used up in the reaction.  The given moles are less than the required moles.

Theoretical yield : It is calculated from the amount of the limiting reagent present in the reaction.

Actual yield : It is experimentally determined.

All the given statements are true.

Final answer:

The limiting reactant is the reactant that is completely consumed in a chemical reaction. The reactant in excess is any reactant that occurs in a quantity greater than that required to completely react with the limiting reactant. The amount of product can be calculated based on the amount of limiting reactant.

Explanation:

1. True. The limiting reactant is the reactant that is completely consumed in a chemical reaction. It determines the amount of product that can be formed.

2. True. The reactant in excess is any reactant that occurs in a quantity greater than that required to completely react with the limiting reactant.

3. True. The amount of product can be calculated based on the amount of limiting reactant using stoichiometry.

Which kind of wave increases in height due to strong winds?

Answers

The kind of wave that increases in height due to strong winds is a surface wave. Surface wave is a type of mechanical wave where it propagates along the interface of two different media. They have larger amplitudes and longer wavelengths. The height of these waves depends on the two different medias.

Answer: Ocean surface wind

Explanation: Ocean surface wind are generated in the ocean due to the abrasion or rubbing between the prevailing wind and the surface waves. They are formed at the top of the ocean surface.

When the wind is very strong, it generates surface waves of bigger wavelength and bigger height. But at the bottom, the waves moves at a slower rate. This waves are formed due to the wind.

This waves can rise upto hundreds of feets during tsunamis. Thus, this waves breaks as they reach the shoreline.

Is a White Dwarf a star? yes or no

Answers

Answer: Yes.

Explanation:

     A white dwarf is the last "stage" for low- and medium-mass stars, it is what stars become after they have exhausted their fuel. They are verydense stars as they are the remaining core of stars. They're typically the size of a regular planet. White dwarves are not the type of stars we usually think of, but they are still stars.

The mass number of an isotope of uranium is 238, and its atomic number is 92. Which symbol best represents this isotope of uranium?

Answers

Answer: The isotope will be represented  by symbol ^(238)_(92)U .

Solution:

The isotope of an element is represented by:

^(A)_(Z)X

X = Symbol of an element

Z = Atomic Number of that element = Total number of electrons or protons

A = atomic mass of that element = Z+ total number of neutrons

So the uranium isotope with atomic mass of 238 and atomic number of 92 will be written as:

^(238)_(92)U

Answer:

B. 238/92 U
