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^(-)

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.

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

Due to the surface tension of water and the crystals ability of diffusion the crystals are placed at the bottom of the beaker of water​.

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.

Answer:

0 to +8, and −2

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

Melting point: 2,250° C (4,082° F)

and the most stable oxidation state of ruthenium is +8

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)

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

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.
