Answer:
The stable ion the sulfur would form is the sulfide ion,
Explanation:
When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.
Sulfur is an elemental atom that has an atomic number of 16 and an atomic mass of 32.065 amu. If the sulfur atom gains three protons then potassium will be formed.
What is a proton?A proton has been a sub-atomic particle that has been known to carry a positive charge and are tend to remain inside the nucleus with the neutrons bonded together by the nuclear force.
The proton of the atom is the characteristic property of the element in the periodic table. They are the sole sub-atomic particle that gives the atomic number of the elemental atom.
The sulfur atom has the atomic number 16 which means it has 16 protons, so if three protons are added to it then the number f protons become 19 which is an atomic number of the potassium (K) element.
Therefore, a potassium element is formed.

A. 1C2H6 + 502 – 2002 + 3H20
B. 2C2H6 + 502 + 4002 + 6H20
O C. 2C2H6 + 702 4CO2 + 6H20
O D. 2C2H6 + 1002 > 4CO2 + 6H20
Answer:
C
Explanation:
Assuming you had a few typos in the equations, I would say C
I am going to assume the reaction
_C2H6 + _O2 → _CO2 + _H2O
Right now, there is enough hydrogen to make 3 water molecules, but since oxygen comes in groups of 2, it wouldn't work.
Therefore, we need 2 ethane molecules.
2C2H6 + _O2 → _CO2 + _H2O
Then balance the right side with the carbons and hydrogens
2C2H6 + _O2 → 4CO2 + 6H2O
So we need 4 O2's in carbon dioxide and 3 O2's in water (Since water uses 1 oxygen molecule per 2 hydrogens). Hence we will need 7 oxygens
2C2H6 + 7O2 → 4CO2 + 6H2O
And assuming errors in the typing, C should be the answer (if this matches)

The minimum stream velocity necessary to transport a sediment particle that is 0.1 centimeter in diameter is closest to
Answer:
5.0 cm/s
Explanation:
Q = V * A
given that the diameter of the particle = 0.1 cm
V = stream velocity , A = cross sectional area of stream , Q = stream flow
For a particle with a diameter of 0.1 cm,
To determine the stream velocity we will use a stadia rod to measure at least 5 meters down ( depth of stream ) three times and then take the average value which will be used to determine the cross sectional area of the stream but Given that the width of the stream is not given the closet value to the stream velocity will be = 5.0 cm/s

Which reaction type is really part of another type of reaction but treated separately? Explain
Answer:
Oxidation - reduction reaction which is called redox reaction.
Explanation:
The type of reaction that is a part of another type but treated separately is called Oxidation - reduction reaction.
Thus is because they usually involve 2 separate half reactions which are oxidation reactions that involve loss of electrons and then reduction equations which involve gain of electrons.
They are treated separately for example when sodium reacts with chlorine to form sodium chloride.
2Na + Cl2 = 2NaCl
Now, sodium undergoes oxidation by loosing elctrons and it's half reaction is;
2Na → 2Na^(+) + 2e^(-)
Meanwhile chlorine undergoes reduction by gaining electrons and its half reaction is;
Cl2 + 2e^(-) → 2Cl^(-)

Balance the following chemical equation by providing the correct coefficients:
[ ]HBr + [ ]Ba(OH)2 -> [ ]BaBr2 + [ ]H20
Answer:
2HBr + Ba(OH)2 → BaBr2 + 2H2O
Explanation:
Hydrogen Bromide + Barium Hydroxide = Barium Bromide + Water
The balanced chemical equation with the correct coefficients is 2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O.
First balancing the barium (Ba) atoms first. There is one barium atom on the left side and one on the right side, so no coefficients are needed for barium.
HBr + Ba(OH)₂ → BaBr₂ + H₂O
There is one hydrogen atom on the left side and two hydrogen atoms on the right side. To balance the hydrogen, place a coefficient of 2 in front of HBr:
2HBr + Ba(OH)₂ → BaBr₂ + H₂O
There are two bromine atoms on the left side and two bromine atoms on the right side, so they are already balanced.
2HBr + Ba(OH)₂ → BaBr₂ + H₂O
There is one barium atom on the left side and one barium atom on the right side, so they are already balanced.
Balance the oxygen (O) atoms. There are two oxygen atoms on the left side and only one on the right side. To balance the oxygen, place a coefficient of 2 in front of H₂O.
2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O

What does q = 0.75 g x 0.897 J/g•°C x 22°C equal?
Answer:
14.8005 Joules
Explanation:
This question is describing the calculation for the amount of heat (Q) a substance absorbs or releases. The amount of heat, Q, is calculated using the formula:
Q = m × c × ∆T
Where;
Q = amount of heat (Joules)
m = mass of substance (g)
c = specific heat of substance (J/g°C)
∆T = change in temperature of substance i.e. final temperature - initial temperature (°C).
According to this question, the following expression is given:
q = 0.75 g x 0.897 J/g•°C x 22°C
To calculate this further, this will equal to: 14.8005
This means that the amount of heat, q, absorbed or released by that substance is equal to 14.8005 Joules.

A certain element has only two naturally occurring isotopes: one with 18 neutrons and the other with 20 neutrons. The element forms I- charged ions when in ionic compounds. Predict the identity of the element. What number of electrons does the charged ion have?
Answer:
[Cl-18]⁻ & [Cl-20]⁻
Explanation:
By definition isotopes are elements with the same number of protons by different number of neutrons. Elements X-18 & X-20 have 17 protons and represent Chlorine isotopes Cl-18 & Cl-20 each with 17 protons and 18 electrons to give the isotopes a -1 oxidation state. Both isotope of chlorine have 7 electron in its valence shell and 10 electrons in its core structure. Gaining 1 electron fills the valence octet and establishes a -1 oxidation state.

Explanation:
Answer:
In addition to carbonyl and organometallic compounds in the low oxidation states −2, 0, and +1, ruthenium forms compounds in every oxidation state from +2 to +8. Very volatile ruthenium tetroxide, RuO4, used in separating ruthenium from other heavy metals, contains the element in the +8 oxidation state.
Valence: 1, 2, 3, 4, 5, 6, 7, 8

What is diffusion?Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.
