A compound is known to contain 15% sulfur.
What mass of sulfur does this correspond to if there is a total of 200g of the compound containing sulfur?
Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.

Complete the Lewis structures for diazine (C5H4N2) showing the two most common resonance forms. Draw the Lewis structures with the formal charges minimized.
Answer:
See explanation and image attached
Explanation:
Lewis structures dot structures that show the number of valence electron in a molecule. Sometimes, we show bonded electrons using a single line as in the image attached.
Two images are shown. They are the both resonance structures of diazene. The both structures only differ in the arrangement of electrons as we can see from the image.

In continuing to think about the rock cycle, we know the phases can take thousands, even millions of years to occur. Which stage in the cycle can happen in mere hours or days?
a. Lithification and Erosion
b. Heat and pressure
C. Compaction and weathering
d. Cooling & Crystallization
Answer:
d. Cooling & Crystallization
Explanation:
One of the stages of the rock cycle that can take place under mere hours or days is cooling and crystallization.
Cooling and crystallization of lava on the earth surface is a very rapid and fast process.
When magma from within the earth reaches the surface, it becomes lava. Due to the nature of the surface, it cools rapidly and very fast to form very fine grained igneous rocks.

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Nucleus Nucleus Atom 1 Atorn 2 Nucleus Nucleus Atom 3 Atom 4 Which two atoms are of elements in the same group in the periodic table?
Explanation:
The atoms of elements on the same period on the periodic table typically have the same number of valence electrons.
They have the same electronic configuration.
Valence electrons are electrons in the outermost shell of an atom.
The number of electrons in an atom is a good indicator of elements that might potentially belong to the same group.
How much Ag can be produced if one is given 64 g of Ag2O?
mass Ag = 59.5 g
Further explanationGiven
64 g of Ag2O
Required
Mass of Ag
Solution
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
mass of Ag in Ag2O :
= ((2 x Ar Ag)/molar mass Ag2O )x mass Ag2O
[tex]\tt mass~Ag=\dfrac{2.Ar~Ag}{MW~Ag_2O}\times mass~Ag_2O[/tex]
Ar Ag : 107,8682 g/mol
MW Ag₂O = 231,735 g/mol
Input the value :
mass Ag = ( (2 x 107,8682 g/mol )/ 231.735) x 64 g
mass Ag = 59.5 g
Or we can use reaction
2Ag₂O ⇒ 4Ag + O₂
mol Ag₂O :
= 64 : 231.735
= 0.276
mol Ag :
= 4/2 x moles Ag₂O
= 4/2 x 0.276
= 0.552
mass Ag :
= 0.552 x 107,8682 g/mol
= 59.54 g

How can we separate a homogenous mixture (a solution)? For example, how can we separate salt that has been dissolved in water?
Answer:
Well, to separate salt from water, you would stir the two together to create a homogenous mixture. Then you would boil the mixture; all the water would evaporate, leaving behind the salt
Explanation:
The sample is made up of neutral atoms. Using the information in the diagram shown, determine the number of protons, neutrons, and electrons found in each atom of your sample
Explanation:
Atoms are generally made up of three fundamental particles which are the protons, neutrons and electrons.
Protons are the positively charged particles within an atom.
Electrons carry negative charges.
Neutrons do not carry any charges.
When an atom is neutral, the number of protons and electrons within the atom is the same.
A charged atom will have a difference in the number of protons and electrons they contain.

Answer:
2 : 2
Explanation:
The balanced chemical equation is given as:
2K + Cl₂ → 2KCl
From the balanced reaction equation, we can conclude that;
2 moles of K will react with 1 mole of Cl₂ 2 moles of K will produce 2 moles of KCl 1 mole of Cl₂ will produce 2 moles of KClTherefore, the mole ratio is 2:2 or 1:1 in the simplest form.

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
A
The gases reflect all of the heat from the Sun, preventing it from reaching Earth's surface.
B
The gases absorb all of the heat from Earth's surface, preventing it from radiating into space.
С
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface.
D
The gases reflect some of the heat from Earth's surface, holding it away from the surface in space.
Answer: The answer is c
Explanation:
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.
What is atmosphere?Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of the earth shields its people by absorbing dangerous sun rays and preserving a constant temperature. It protects Earth from many space hazards and enables life there. As a result, it is crucial for regulating climate and a source of life on planet.
The majority of the infrared energy from the Sun is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds, creating the greenhouse effect. This causes the lower atmosphere and the Earth's surface to warm.
Thus, the gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.
