how does tungsten most common isotope relate to the average atomic mass of the element
Answer:
It has the most quantitative effect on the average atomic mass of the element.
Explanation:
Tungsten's most common isotope will have the most quantitative effect on the average atomic mass.
The most common isotope of tungsten will represent its most abundant isotope.
The proportion by which each element occurs in nature is the geonormal abundance. The geonormal abundance is used to calculate the average atomic mass.The isotope with the most geonormal abundance will have the highest effect on the average atomic mass of an element.

What would the total mass of a 4.9 mole sample of Barium (Ba) be if its Molar Mass is 137g?
O 132g
O 142g
O 671g
Answer:
m = 671 grams
Explanation:
Given that,
No of moles, n = 4.9
Molar mass of Barium, M = 137 g
Mass divided by molar mass is equal to no of moles. It can be given by the formula as follows :
[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=4.9\times 137\\\\m=671.3\ g[/tex]
or
m = 671 grams
So, the total mass of the sample of Barium is 671 grams.

The mass spectrum of the element Sb is most likely represented by which of the following?
A. 122 Atomic Mass
B. 121 and 123 Atomic Mass
C. 120, 123 and 124 Atomic Mass
D. 120,121 and 124 Atomic Mass
i know the answer is b i just need an explanation
Mass spectrometry is the technique that measures the ratio of mass to charge. The spectrum of the element Sb is most likely represented by 121 and 123 atomic mass. Thus, option B is correct.
What is Mass spectrometry?Mass spectrometry plots the spectrum representing the ratio of mass-to-charge by the signals generated by the ions. The spectrum estimates the mass and isotopes of the sample elements. They also determine the chemical properties and structures.
The spectrometry detects the isotopes that are stable and are known to have the same atomic number. It can be used to determine the isotopes of an element based on their peaks generated on the mass spectrum. Antimony has two stable isotopes with atomic masses 121 and 123.
Therefore, option B. the spectrum of the element Sb is most likely represented by Sb-121 and Sb-123.

Use the following chemical equation to answer the question:
2 K + MgBr2 ⟶ 2 KBr + Mg
Which elements or compounds are the reactants?
1. K and MgBr2
2. MgBr2 and Mg
3. KBr and Mg
4. K and KBr
Answer:
Option 1. K and MgBr2
Explanation:
From the question given above, we obtained the following data:
2K + MgBr2 —> 2KBr + Mg
In a chemical reaction, the reactants are located on the left side of the equation while the products are located on the right side.
The reactants are separated from the products by an arrow sign.
Considering the question given above,
Element /compound >>> location
K, MgBr2 >>>>>>>>>>>>> Left
KBr, Mg >>>>>>>>>>>>>> Right
From the illustration above, the reactants (i.e element/compound on the right side) are K and MgBr2

If carbon lost one proton, what atom would be formed
Answer:
boron
Explanation:
boron has 5 protons and carbon has 6, so if carbon lost a proton, it would become boron since each element has a unique number of protons.
As each element has a different number of protons, boron has five and carbon has six, so if carbon lost one of its protons, it would change into boron.
What is proton ?Every atom has a proton, a subatomic particle, in its nucleus. The particle possesses an electrical charge that is positive and opposite to the electron's.
In the reaction, a proton is forfeited. Keep in mind that when the number of protons changes, the atomic number also changes, creating a new element. Carbon-14 is the end result as a result. It is a new element, yet it has the same mass as nitrogen-14.
When carbon creates covalent bonds, pairs of electrons are shared between the atoms instead of being gained or lost as happens with chemical bonds. The ability of carbon to construct lengthy chains of atoms and so create intricate biological compounds is due in part to this feature.
Thus, If carbon lost one proton, boron atom would be formed.

The atomic weight of iodine is less than the atomic weight of tellurium. However, Mendeleev listed iodine after tellurium in his original periodic table because he suspected the atomic weights for these elements were inaccurate. What was Mendeleev's reason for this suspicion?
Explanation :
As we know that Mendeleev arranged the elements in horizontal rows and vertical columns of a table in order of their increasing relative atomic weights.
He placed the elements with similar nature in the same group.
According to the question, the atomic weight of iodine is less than the atomic weight of tellurium. So according to this, iodine should be placed before tellurium in Mendeleev's tables. But Mendeleev placed iodine after tellurium in his original periodic table.
However, iodine has similar chemical properties to chlorine and bromine. So, in order to make iodine queue up with chlorine and bromine in his periodic table, Mendeleev exchanged the positions of iodine and tellurium.
As we know that the positions of iodine and tellurium were reversed in Mendeleev's table because iodine has one naturally occurring isotope that is iodine-127 and tellurium isotopes are tellurium-128 and tellurium-130.
Due to high relative abundance of tellurium isotopes gives tellurium the greater relative atomic mass.

Explain how plate tectonics have changed Earth's surface over time. Include the role of plate tectonics in the creation of landforms.
Answer: The theory of plate tectonics tells us that the earth's surface sits on plates that shift due to the built up pressure underneath. When the pressure gets too much, it has to escape somewhere so it goes to the edges of the plate and causes earthquakes. This in turn causes the surface to shift.
