The pH of a solution with a Hydronium (H30+) ion concentration of 0.001M is

Answers

Answer 1

Answer:

The pH of a solution with a Hydronium (H₃O⁺) ion concentration of 0.001 M is 3.

Explanation:

pH, short for Hydrogen Potential, is a measure used to establish the level of acidity or alkalinity of a solution.

pH indicates the amount of hydrogen ions present in a solution or substance. Mathematically the pH is the negative logarithm of the molar concentration of hydrogen ions or protons (H⁺) or hydronium ions (H₃O⁺).

pH= - log [H⁺]= - log [H₃O⁺]

The pH scale goes from 0 to 14. Values less than 7 indicate the range of acidity and those greater than 7 indicate alkalinity or basicity. The value 7 is considered neutral.

In this case, [H₃O⁺]= 0.001 M.

Replacing in the definition of pH:

pH= - log (0.001 M)

Solving:

pH= 3

The pH of a solution with a Hydronium (H₃O⁺) ion concentration of 0.001 M is 3.

When calcium carbonate is heated strongly, carbon dioxide gas is evolved. CaCO3(s) → CaO(s) + CO2 (g) If 4.74 g of calcium carbonate is heated, what volume of CO2 (g) would be produced when collected at STP?

Answers

Answer:

1.06 liters of gas are produced

Explanation:

Our reaction is:

CaCO₃(s) → CaO(s) + CO₂ (g)

This is the decomposition of calcium carbonate.

Ratio is 1:1:1

1 mol of carbonate can decompose to 1 mol of oxide and 1 mol of oxygen.

We convert mass to moles:

4.74 g . 1 mol /100.08g = 0.0474 moles

These are the moles of oxygen produced.

We know that 1 mol of any gas at STP is contained in 22.4L

0.0474 mol . 22.4L /mol = 1.06 L

What effect does an increase in carbon dioxide (CO 2 ) have on the concentration of hydrogen ions (H^ + ) in the blood?

Answers

Answer:

As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right.

cutting paper is not an example of chemical change.

Explanation:

cutting paper is physical change, its physical properties (size, shape ) change but chemical composition remain same.

The cutting paper is not a example of chemical change of a chemical reaction.

What is chemical reaction?

The kind of reaction in which one kind of element get converted into another kind of elements or molecule is referred as chemical reaction.

What is chemical changes?

Chemical changes take place when a material combines with the other to generate a new substance, a process known as chemical synthesis, or when a molecule decomposes into more than one separate chemicals, a process known as chemical decomposition. These processes are known as chemical reactions, and they are generally irreversible unless they are followed by more chemical reactions.

Cutting paper is just a physical change not chemical change since the paper's characteristics did not change; only the shape, which would be a physical attribute, changed. The term "chemical change" refers to a change in a substance's chemical properties. Burning of paper, for example, or rusting of iron.

Therefore, cutting paper is not a example of chemical change.

How much so you can be dissolved and 50 mL of water at 30 Celsius see chart:)

Answers

Answer:

The correct answer is - 100 grams.

Explanation:

The solubility graph is a very useful tool because it tells you the amount of solute that can be dissolved per 100 mL of water in order to have a saturated solution of potassium nitrate at a given temperature.

In order to find the solubility of the salt at 30 ∘ C , start from the 30 ∘ C

mark on the graph and move up until you intersect the curve. At the point of intersection, move left until you intersect the y axis and read off the value that you land on which is 200. However, it is for 100 ml so half the value you read:

200/2 = 100 gram .

So, solubility ≈ 100 g / 50 mL water

So, a saturated solution of solute will hold about 100 g of dissolved solute, that is of dissociated solute, per 50 mL of water at 30 ∘ C .

A sample of gas is inside of a rigid container with fixed volume of 350mL. The initial pressure of the system is 366kPa, and the initial temperature is 88 degrees Celsius. How would the pressure of the system change if the temperature was increased to 110 degrees Celsius?

Answers

Answer:

457.5kPa

Explanation:

Given data

V1=V2=350mL (fixed volume )

P1=366kPa

T1= 88 degrees Celsius

P2=??

T2= 110 degrees Celsius

For the general gas equation

P1V1/T1= P2V2/T2

V1=V2

P1/T1= P2/T2

Substitute

366/88= P2/110

Cross multiply we have

P2*88=366*110

P2*88= 40260

P2= 40260/88

P2= 457.5 kPa

Hence the pressure will change to 457.5kPa

A gas made up of homonuclear diatomic molecules escapes through a pinhole 3.98 times as fast as oxygen gas. Write the Chemical formula of the gas.

Answers

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

Graham's law:

[tex]\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }[/tex]

Where V is the speed of the gases and m the molar mass of those:

As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)

[tex]3.98 =\sqrt{\frac{32g/mol}{m_A} }[/tex]

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

how much heat is required to increase the temperature of 20 grams of water by 26 degrees celsius?

Answers

Answer: 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.

Explanation:

Given: Mass = 20 g

Change in temperature = [tex]26^{o}C[/tex]

The standard value of specific heat of water is [tex]4.184 J/ g^{o}C[/tex]

Formula used to calculate the heat energy is as follows.

[tex]q = m \times C \times \Delta T[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat of substance

[tex]\Delta T[/tex] = change in temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times \Delta T\\= 20 g \times 4.184 J/g ^{o}C \times 26^{o}C\\= 2175.68 J[/tex]

Thus, we can conclude that 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.

How does temperature relate to energy?

Answers

Temperature, the average kinetic energy of particles, tells you how warm something is. Thermal energy, the total kinetic energy of the particles, tells you the extent to which a substance or object can transfer heat or make something else warmer. If an object's temperature increases, its thermal energy increases also.

Answer:

temperature a measurement of the average amount of energy PER UNIT OF STUFF

Heat Energy is TOTAL ENERGY IN THE STUFF

So, that's why the difference. If you have two things at the same temperature, then any one mole (which is the same as how many molecules or atoms it takes to make up the molecular weight of something in grams.. so one mole of Hydrogen weighs 1 gram, 1 mole of helium weighs 2 grams, 1 mole of Gold weight 196 grams) of the stuff will have the same amount of energy as one mole of the other stuff. If you measure by total mass though, then you realize that there are more water molecules than gold ones in the same volume of stuff, and heat is about volume and molecular density, not mass.

This is why some Stirling engine folks who have made solar plants use Helium as the working gas.. it contains a huge amount of heat for its volume (also because it is very compressible)

So.. Delta Q goes with moles, not mass.
