CCl4(l) is placed in a previously evacuated container at 30°C , and some of the CCl4(l) evaporates. In the box below, draw a particulate diagram to show the species in the container after some of the CCl4(l) has evaporated. The phases of the species should be indicated by the spacing and distribution of the particles in the diagram. Some of the species shown in the legend will not be used.
Answers
Answer:
The phases of the species should be indicated by the spacing and distribution of the particles in the diagram
Explanation:
Evaporation would be a phase change from liquid to gas where intermolecular forces are broken CCl4 (l) -> CCl4 (g)
Diagram is attached below
We have that from the diagram that when CCl4(l) is placed in a previously evacuated container at 30°C , and some of the CCl4(l) evaporates that the molecules of CCl4(g) becomes loosely held and apart from while in its closely held in its liquid state.
From the question we are told

Which of these elements has an electron configuration of [Kr]5s2?
barium
calcium
rubidium
strontium
Answers
Strontium has an electron configuration of [Kr]5s²
Further explanationIn an atom there are levels of energy in the shell and sub shell
This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is
s: 2 electrons
p: 6 electrons
d: 10 electrons and
f: 14 electrons
From an electron configuration of [Kr]5s² can be concluded :
element is in period 5 (5 = shell)element is group 2(valence electron =2 and block s) has atomic number 38 (Kr = 36 + 2(valence elektron from 5s²)If we look at the periodic system, the elements that meet the requirements in question are Strontium (Sr)

If Maria winks exactly 5 times every minute while she is awake and she sleeps exactly 8 hours a day, how many times does Maria wink in a day? winks/day.
Answers
Answer:4,800
Explanation:
5 winks a minute, 60 minutes in an hour.
300 winks an hour, 16 hours a day.
4,800.
Answer:
The answer is 4,800 winks per day.
Explanation: There are 24 hours in a day, 24 minus the 8 hours shes asleep is 16. There are 60 minutes in an hour. 5 x 60 is 300. 300 winks an hour multiplied by the 16 hours she's awake is 4,800.

You are an employee at "cash for gold" and a customer comes in looking to exchange gold for money. They claim to have 3.47 gram nugget of fold. How many particles (atoms) of gold are in one nugget? With work shown
Answers
Answer:
The number of atoms in 3.47 gram nugget of gold is approximately 1.0606 × 10²² atoms
Explanation:
The given mass of gold = 3.47 grams
The molar mass of gold = 196.96657 g/mol
The number of moles of gold in 3.47 grams of gold = 3.47 grams/(196.96657 g/mol)
The number of moles of gold in 3.47 gram nugget of gold = 0.01762 moles
The number of atoms in one mole of gold = 6.02 × 10²³ atoms
The number of atoms in 0.01762 moles of gold = 6.02 × 10²³ atoms/mole × 0.01762 moles
The number of atoms in 0.01762 moles of gold ≈ 1.0606 × 10²² atoms
∴ The number of atoms in 3.47 gram nugget of gold ≈ 1.0606 × 10²² atoms.

b.
It causes the global concentration of carbon dioxide to decrease.
c.
The water in the melting glaciers can cause sea levels to rise.
d.
None of the above is true.
Please select the best answer from the choices provided
A
B
C
D
Answers
Answer:
The correct answer is option "C"
The water in the melting glaciers can cause sea levels to rise.
The increase in annual melt season indicates a prolonged melting (hot) season which is primarily due to the impact of global warming. Global warming is increasing the highest temperature mark in the hot seasons on the planet which is adversely affecting the polar regions of earth. The ice in these Polar Regions has started melting. This ice when converted into liquid form flows through regions to reach sea and oceans and thus causes the rising of sea level
The annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.
What is the annual melt season?The annual melt season refers to a period of time when the ice in cold and polar regions of the world begin to melt to form warm.
The melting of ice in these regions such as Antarctica results in a rise in the global sea levels.
Therefore, the annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.
