Answer: Atoms of different elements are found to have different number of protons, neutrons, and electrons. To distinguish one atom from another or to classify the various atoms, a number which indicates the number of protons in the nucleus of a given atom, is assigned to the atoms of each identified element. This number is known as the atomic number of the element. The atomic numbers for some of the elements which are associated with the study of semiconductors are given in the following table.
Explanation:
Element Symbol Atomic Number
Silicon Si 14
Germanium Ge 32
Arsenic As 33
Antimony Sb 51
Indium In 49
Gallium Ga 31
Boron B 5
Answer:
Dalton's law is fulfilled, since the elements in each compound of the example are related to each other in different proportions forming two different compounds; so for case a) and b) you have 15.54% and 9.323% P respectively for each compounds, that are equivalent to 0.2912 g P for every g Cl and the other produced 0,1747 g P for every g Cl.
Explanation:
Dalton's Law ( law of multiple proportions):
When two or more elements combine to give more than one compound, a variable mass of one of them joins a fixed mass of the other, and the first is related to canonical and indistinct numbers.
a) for the compounds A:
⇒ 0.2912 g P / gCl * ( 35.45 g CL / mol CL) * ( mol Cl / mol PCl ) * ( mol PCl / 66.427 g PCl ) = 0.1554 g P / g PCl
⇒ % P = 0.1554 * 100 = 15.54 %
b) for the compunds B:
⇒ 0.1747 g P / g Cl * ( 35.45 g Cl / mol Cl ) * ( mol Cl / mol PCl ) * ( mol PCl / 66.427 g PCl ) = 0.09323 g P / g PCl
⇒ % P = 9.323 %
Answer:
Hi, this is a super vague question, so its pretty confusing to answer. Could you please be a bit more specific?
If you are referring to chemistry, then how you tell "what is what" is by the molecular makeup of an element (Periodic table), and "how that..affects what", chemical reactions can occur between elements
the temperature, internal energy and kinetic energy
