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)
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.

Which statement is true concerning visible light and the electromagnetic spectrum?
A.
Visible light is a large portion of the electromagnetic spectrum.
B.
Visible light is a small portion of the electromagnetic spectrum.
C.
All electromagnetic radiation is considered to be visible.
Answer:
The true statement concerning visible light and electromagnetic radiation is considered to be - d. Visible light is a small portion of the electromagnetic spectrum.
The electromagnetic spectrum is the range of frequencies of electromagnetic waves or radiations. This spectrum also gives an idea about the wavelengths of electromagnetic radiations. The part of the spectrum on their higher to lower energy or frequency range from Hz to Hz are:
gamma rays
X-rays
ultraviolet radiation
visible light
infrared radiation
radio waves.
The visible light is the very small part of the electromagnetic spectrum that ranges from the to, Visible light is the light that the human eye can see.
Thus, the correct answer is- option d.

Explain how changing the amount of greenhouse gases in the atmosphere affects the flow of heat out of Earth's atmosphere.
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.
Explain why a hydrogen atom doesn’t have a neutron in its nucleus.

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)
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.

Which statement describes a shortcoming of Rutherford’s model of the atom?A.
It incorrectly placed most of the atom’s mass in the nucleus.
B.
It did not explain how electrons behaved and why they don’t collide with the nucleus.
C.
It did not account for the fact that atoms have equal numbers of protons and electrons.
A shortcoming of Rutherford’s model of the atom is it did not account for the fact that atoms have equal numbers of protons and electrons. Therefore, option C is correct.
What is rutherford's model ?Ernest Rutherford, a scientist who was born in New Zealand, developed the Rutherford model to explain an atom. Rutherford oversaw the Geiger-Marsden experiment, which, after Rutherford's analysis in 1911, indicated that J. J. Thomson's plum pudding model of the atom was flawed, in 1909.
The first person to recognize an atom's nucleus was Rutherford. He attacked gold with -particles and discovered that there was positively charged material inside the atom as a result.
It did not explain the distribution of the atom's negatively charged electrons around its positively charged nucleus.
Thus, option C is correct.

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.
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.
