Hello there!
Electronegativity is the atom's tendency to attract electrons in a chemical bond
There are two trends to electronegativity:
Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example) Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.
Sn belongs to group 4A (group 14) Sb belongs to group 5A (group 15)Te belongs to group 6A (group 16) I belongs to group 7A (group 17)As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity
Hope this helps!

If an ionic compound has a 2- charge how does that affect the total number of electrons in a Lewis structure
Answers
In the situation where an ion has a charge of -2, the Lewis structure is affected because it must add two additional electrons.
The Lewis structure is a term to refer to the graphical representation that shows the pairs of electrons in dashes or points of bonds between:
The atoms of a moleculeThe lone electron pairs that may existAdditionally, the charge of an ionic compound is calculated using the difference in electrical charge between the electrons. On the other hand, an ion is formed by adding or removing electrons, so the magnitude of the resulting charge depends on the number of electrons added or removed.
According to the above, if an ionic compound has a -2 charge, the Lewis structure must add two electrons.

Answers
Explanation:
The added greenhouse gases absorb the heat. They then radiate this heat. Some of the heat will head away from the Earth, some of it will be absorbed by another greenhouse gas molecule, and some of it will wind up back at the planet's surface again. With more greenhouse gases, heat will stick around, warming the planet.

Given the reaction below, how many grams of Li3N can be formed from 6.07 g of Li? Assume an excess of nitrogen.
6 Li(s) + N2(g) → 2 Li3N(s)
Answers
Answer:
About 10.2 g Li₃N.
Explanation:
We are given the reaction:
[tex]\displaystyle \text{6 Li(s) + N$_2$(g) }\longrightarrow \text{2 Li$_3$N(s)}[/tex]
And we want to determine the amount of Li₃N that can be formed from 6.07 g of Li and an excess of nitrogen.
To convert from g Li to g Li₃N, we can: (1) convert from g Li to mol Li, (2) mol Li to mol Li₃N, and (3) mol Li₃N to g Li₃N.
The molecular weight of Li is 6.94 g/mol. From the equation, six moles of Li yields two moles of Li₃N. And the molecular weight of Li₃N is 34.83 g/mol as shown below.Molecular weight of Li₃N:
[tex]\displaystyle \begin{aligned}\text{MW}_\text{Li$_3$N} & = (3 (6.94) + 14.01) \text{ g/mol} \\ \\ & =34.83\text{ g/mol} \end{aligned}[/tex]
This yields three ratios:
[tex]\displaystyle \frac{1 \text{ mol Li}}{6.94 \text{ g Li}}, \frac{2 \text{ mol Li$_3$N}}{6 \text{ mol Li}}, \text{ and } \frac{34.83 \text{ g Li$_3$N}}{1 \text{ mol Li$_3$N}}[/tex]
From the initial value, multiply:
[tex]\displaystyle 6.07 \text{ g Li} \cdot \frac{ 1 \text{ mol Li}}{6.94 \text{ g Li}} \cdot \frac{2 \text{ mol Li$_3$N}}{6 \text{ mol Li}} \cdot \frac{34.83 \text{ g Li$_3$N}}{1 \text{ mol Li$_3$N}} = 10.2\text{ g Li$_3$N}[/tex]
In conclusion, 10.2 g of Li₃N is formed from 6.07 g of Li and an excess of nitrogen.
How does the rock cycle and plate tectonics interfere with geochemists trying to determine the age of the Earth? Chose the best answer.

Explanation:
Rock cycle(Attachment-1)
The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.
What are rock cycle?The rock cycle is defined as the process through which the three main rock types i.e. igneous, metamorphic and sedimentary rock transfer from one type to another type.
The plate tectonics is defined as a theory that earth's outer shell is divided into large slabs of solid rocks known as "plates" that glide over earth mantle, the rocky inner layer above earth's core.
Thus, the rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.

If 8.0 g of sulfur dioxide came in contact with a cloud containing 2.2 g of oxygen, indicate the
Limiting Reactant and calculate the theoretical yield (in grams) of sulfur trioxide produced.
Answers
Answer:
Limiting reactant= SO₂, Theoretical yield = 9.6g SO₃
Explanation:
The first step is is to find the limiting reactant; you do this using stoichiometry.
The reactant that produces the smallest amount of sulfur trioxide SO₃, is the limiting reactant.
In this problem, SO₂ is the limiting reactant.
Now to find the theoretical yield we will use the smallest value of SO₃.

In a living organism, the organic material contains 0.22 Bq of 14C per gram of carbon. A sample of charcoal from a campfire contains 0.055 Bq of 14C per gram of carbon. How long ago was this campfire in use? (14C half-life is 5730 yr)
Answers
Answer:
6
Explanation:
The age of the charcoal sample in the campfire in use is equal to the time taken for the decay of 0.22 of C-14 to 0.055 Bq. Hence its age is 11552.45 years.
What is radioactive decay?Unstable radioactive isotopes of atoms undergo nuclear decay by the emission of charged particles such alpha or beta particles. Radioactive decay is a first order reaction. Thus, the decay constant is written as:
k = 1/t ln (W0 / Wt)
where W0 be the initial weight and Wt be the weight after time t.
The decay constant is related to the half life time of the sample by the expression:
k = 0.693 / t1/2.
Given that t1/2 of C-14 = 5730 years.
Thus, k = 0.693 /5730 = 0.00012 yr⁻¹.
Now, we can calculate the time t using the first order equation.
t = 1/k ln ln (W0 / Wt)
= [ ln (0.22 Bq/ 0.055 Bq) ] / 0.00012 yr⁻¹
= 11552.4 years.
Therefore, the age of the sample of charcoal is 11552.4 years.
