Answer:

. All redox reactions occur with a simultaneous change in the oxidation numbers of some atoms. At least two elements must change their oxidation numbers. When an oxidation number of an atom is increased in the course of a redox reaction, that atom is being oxidized

Explanation:

Answer:

A substance that tends to bring about oxidation by being reduced and gaining electrons

Explanation:

Answer:

An oxidizing agent is a substance that takes negatively charged electrons "away" from a substance or object; usually taking these electrons for itself it can also transport the electrons from an object and "give" them to another substance or object. The object that has been oxidized will then have a positive charge after losing the negative electrons and the substance receiving the electrons will become negative.

Answer:

Matter is anything that is made up of atoms. Whether its a computer, a drink, a suitcase, a telephone, whatever.

If it has mass, if it occupies space, and if it has volume, then it is matter.

Also, matter comes in the form of solids, liquids, and gasses.

In this case, the telephone is a solid.

Answer:

458.7 mmHg

Explanation:

Step 1:

Data obtained from the question. This includes:

Initial volume (V1) = 70L

Initial pressure (P1) = 600 mmHg

Initial temperature (T1) = 20°C

Final temperature (T2) = 15°C

Final volume (V2) = 90L

Final pressure (P2) =...?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This is illustrated below:

T(K) = T (°C) + 273

Initial temperature (T1) = 20°C

Initial temperature (T1) = 20°C + 273 = 293K

Final temperature (T2) = 15°C

Final temperature (T2) = 15°C + 273 = 288K

Step 3:

Determination of the new pressure of the gas.

The new pressure of the gas can be obtained by using the general gas equation as shown below:

P1V1/T1 = P2V2/T2

600 x 70/293 = P2 x 90/288

Cross multiply to express in linear form

P2 x 90 x 293 = 600 x 70 x 288

Divide both side by 90 x 293

P2 = (600 x 70 x 288) / (90 x 293)

P2 = 458.7 mmHg

Therefore, the new pressure of the gas is 458.7 mmHg

Answer:

HCl is a strong acid, it dissociates 100% (I.e. completely): [HCl]F = 0.020 M = [H3O+] So, pH = - log [H3O+] = -log [HCl]F = -log(. 020)=1.70 Voila!

Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

Explanation: homoestasis is the process by which the body keep it's internal environment constant, regardless of change in the external environment. The human body has a normal range in which it's system operates and it uses homoestasis to keep these at constant.

Homeostasis could be positive or negative. It usually involves a sensor which detects the changes in the body and passes the information to the control center, a control center which receive information from the sensor and sends signals to the effectors and the effector which acts on the information sent by the control center to effect normalcy.

In this case, when a person eats food,he gets glucose. Blood sugar most be kept at constant so the endocrine system release the hormone insulin. Insulin helps to convert glucose to glycogen, which is the form it can be stored in the liver

When the blood sugar levels is low, the brain which is the control center causes glucagon to be released . This hormone converts glycogen to glucose

Answer:

Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

Answer:

Frequency = Velocity / Wavelength

or

f = v / λ

Answer:

Surface area

Explanation:

The rate of a chemical reaction is increased when the surface area of a solid reactant is increased. This can be done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased, it implies more particles are exposed to the other reactant.

When a seltzer tablet is ground into powder, the idea is to expose more of its surface to the other reactant. Since rate reaction depends on effective collision between reactants, more exposed particles implies a greater degree of collision between reactants and a faster rate of reaction.

Answer:

Here's what I get  

Explanation:

Assume the initial concentrations of H₂ and I₂ are 0.030 and 0.015 mol·L⁻¹, respectively.

We must calculate the initial concentration of HI.

1. We will need a chemical equation with concentrations, so let's gather all the information in one place.

                   H₂ +    I₂    ⇌ 2HI

I/mol·L⁻¹:    0.30   0.15         x

2. Calculate the concentration of HI

[tex]Q_{\text{c}} = \dfrac{\text{[HI]}^{2}} {\text{[H$_{2}$][I$_{2}$]}} =\dfrac{x^{2}}{0.30 \times 0.15} = 5.56\\\\x^{2} = 0.30 \times 0.15 \times 5.56 = 0.250\\x = \sqrt{0.250} = \textbf{0.50 mol/L}\\\text{The initial concentration of HI is $\large \boxed{\textbf{0.50 mol/L}}$}[/tex]

3. Plot the initial points

The graph below shows the initial concentrations plotted on the vertical axis.

The initial concentration of the HI at the time 0 sec, has been 0.05 mol/L.

The balanced chemical equation for the reaction has been:

[tex]\rm H_2\;+\;I_2\;\rightarrow\;2\;HI[/tex]

The given initial concentration of hydrogen has been 0.030M, and the given concentration of iodine has been 0.015 M.

The reaction quotient for the following reaction has been:

Reaction quotient = [tex]\rm \dfrac{[HI]^2}{[H_2]\;[I_2]}[/tex]

The concentration of HI for the reaction quotient 5.56 has been:

5.56 = [tex]\rm \dfrac{[HI]^2}{[0.030]\;[0.015]}[/tex]

[tex]\rm [HI]^2[/tex] = 0.0025 M

HI = 0.05 mol/L or 0.05 M.

The concentration of the HI at the initial concentration has been 0.05 mol/L.

The graph attached has been plotted as the concentration as the function of time.

The initial concentration of hydrogen, iodine, and hydrogen iodide have been plotted as the function of time.

Answer:

a new substance is produced

Explanation:

i just took my test and got this question right

The best evidence that a chemical reaction occurs when coal burns is a new substance is produced. The correct option is A.

Coal is a carbon containing fossil fuel, which is formed when the organic matter is decomposed inside the earth with heat and pressure by the earth crust. It is the most used fossil fuel.

Carbon dioxide is a gas produce when these fossils fuel burned. It is a green house gas and increase the warmth of the earth when produced. It is taken by plants to make their food.

When coal burns, it produces carbon dioxide which is a gas and coal is a solid, so here the chemical reaction is happening which is producing a new substance.

Thus, the correct option is A. A new substance is produced.

Salt bridge

Explanation:

Salt bridge is used in an electrolytic cell to transfer electrons from the anode to the cathode.

Salt bridge are used because they do not interfere with the constituents of the cell I.e the anode (+very electrode) and cathode(-ve electrode).

Examples of salt bridges are AgNO₃, KCl etc.

Salt bridge can be described as a tool used to link the oxidation half cell and reduction half cell in an electrolytic set-up or galvanic cell.
