A substance with a ph of 6 is called

Answers

Answer 1

Answer: An acid has a pH of 1-6, while 7 is neutral, commonly used for water.

A substance with a pH of 6 is an acid that is not strong because its close to 7.

Answer 2

Answer:

Final answer:

A substance with a pH of 6 is considered slightly acidic. The pH scale, which measures the concentration of hydrogen ions, ranges from 0 to 14 where a pH of 7 is neutral. A substance with a pH below 7 is acidic, while a substance with a pH above 7 is considered basic or alkaline.

Explanation:

A substance with a pH of 6 is often considered slightly acidic. The pH scale measures the concentration of hydrogen ions (H+) in a substance and ranges from 0 to 14 where a pH of 7 is considered neutral. Anything below 7 indicates an acidic solution, and anything above 7 is considered basic or alkaline. So, a substance with a pH of 6 is closer to the neutral point, but is still acidic as it falls below 7. Since one unit on the pH scale represents a decrease in hydrogen ion concentration by a factor of 10, a solution with a pH of 6 is 10 times less acidic than one with a pH of 5, but 10 times more acidic than a neutral solution at pH 7.

How does the number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen?1) 1 mol of oxygen has fewer molecules.2) 1 mol of oxygen has more molecules.3) Each sample has the same number of molecules.4) The molecules cannot be compared without knowing the mass.

Answers

The number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen is that each sample has the same number of molecules. The answer is number 3

Answer:

3) Each sample has the same number of molecules

Explanation:

1 mol are 6,022x10²³ particles. Moles of a chemical substance represent the number of molecules that this chemical has.

Thus, one mol of oxygen are 6,022x10²³ molecules of oxygen and one mol of nitrogen are 6,022x10²³ molecules of nitrogen.

Right answer is:

3) Each sample has the same number of molecules.

If the system 2CO(g)+O2(g) 2CO2(g) has come to equilibrium and then more CO(g) is added,

Answers

If more CO is added the reaction will shift to the right and produce more products to maintain the equilibrium constant. This can be explained through Le Chatlier principles. I hope this helps. Let me know if anything is unclear.

2) D. self-ionization
3) B. basic
4) C. HCl is a strong acid; HC2H3O2 is a weak acid.
5) Kb = [OH-][C5H5NH+]/[C5H5N]

Answer: 1. B. 1.3

2. D. self-ionization

3. A. acidic

4. HCl is a weak acid; $CH_3COOH$ is a weak acid.

5. A. $K_b=([OH^-][C_5H_5NH^+])/([C_5H_5N])$

Explanation:

1. pH is the negative logarithm of hydrogen ion concentration.

$pH=-log[H^+]$

Given: $[H^+]=5.0* 10^(-2)=0.05$

$pH=-log[0.05M]=1.30$

2. An acid is a substance which donates $H^+$ ions when dissolved in water.

A base is a substance which donates $OH^-$ ions when dissolved in water.

Thus as water ionizes to give both ions, it acts as both acid and base.

$H_2O\rightarrow H^++OH^-$ which is called as self ionization.

3. pH is the measure of acidity or alkalinity of a solution. \Acids have pH less than 7, neutral solutions have pH of 7 and basic solutions have pH more than 7.

As the given solution has a pH of 6.8 which is less than 7, it is an acidic solution.

4. Strong acids are those acids which undergo complete dissociation when dissolved in water.

$HCl\rightarrow H^++Cl^-$

Weak acids are those acids which do not undergo complete dissociation when dissolved in water.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

5. Dissociation constant is the ratio of product of concentration of products to the product of concentration of reactants each raised to their stochiometric coefficients.

$C_5H_5N+H_2O\rightarrow C_5H_5NH^++OH^-$

$K_b=([OH^-][C_5H_5NH^+])/([C_5H_5N])$

The concentration of water is ignored as it is in large excess and thus does not effect the dissociation of pyridine.

Carbon -14 is an example of dating

Answers

Carbon-14 is a radioactive isotope of carbon and is used primarily in radiocarbon dating at archaeological sites since we know the half life for carbon-14 and the ratio of carbon-12 and carbon-14 a living thing probably had when it died and the difference in that ratio can tell us how old the object is.

Why would you add boiling chips/stones to a solution that is to be refluxed? when should you add them?

Answers

Chip stones should be added to a solution that is to be refluxed as they act as nucleation sites for formation of solvent bubbles.

This should be added when the temperature of the liquid is still low.

What are Boiling Chips?

These are usually added to a solution as they contain trappedair which

helps in the reflux process.

The high surface area ensures it acts as nucleation sites and the best time

to dd is when the temperature of the solution is still low for best results.

Answer:

H3AsO4 → As2O5 + H2O

Explanation:

The first equation is balanced:

H3AsO4 → As2O5 + H2O

Here's a breakdown of the balanced equation:

Reactants:

H3AsO4: 3 hydrogen atoms, 1 arsenic atom, and 4 oxygen atoms

Products:

As2O5: 2 arsenic atoms and 5 oxygen atoms

H2O: 2 hydrogen atoms and 1 oxygen atom

As you can see, the number of atoms of each element is the same on both sides of the equation. This means that the equation is balanced.
