Answer:

To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).

Explanation:

0.0917 grams of KOH are needed to neutralize 13.6 mL of 0.12 M HCl in stomach acid.

What is stomach acid?

Stomach acid, also known as gastric acid or gastric juice, is a digestive fluid that is produced in the stomach. It plays a vital role in the process of digestion by breaking down food and providing an acidic environment for the activation of digestive enzymes. Stomach acid is primarily composed of hydrochloric acid (HCl) along with other substances such as mucus, enzymes, and electrolytes.

The balanced equation for the neutralization reaction between HCl and KOH is:

HCl + KOH → KCl + H₂O

From the balanced equation, we can see that the stoichiometric ratio between HCl and KOH is 1:1. This means that for every mole of HCl, we need 1 mole of KOH to completely neutralize it.

First, let's calculate the number of moles of HCl in 13.6 mL of 0.12 M solution:

moles of HCl = volume (in L) * concentration (in mol/L)

= 0.0136 L * 0.12 mol/L

= 0.001632 mol

Since the stoichiometric ratio between HCl and KOH is 1:1, we need an equal number of moles of KOH to neutralize the HCl. Therefore, we need 0.001632 mol of KOH.

Next, we can calculate the mass of KOH using its molar mass:

mass of KOH = moles of KOH * molar mass of KOH

= 0.001632 mol * (39.10 g/mol + 16.00 g/mol + 1.01 g/mol)

= 0.001632 mol * 56.11 g/mol

= 0.0917 g

Therefore, 0.0917 grams of KOH are needed to neutralize 13.6 mL of 0.12 M HCl in stomach acid.

When a 5.0 mL volume of a 0.20 M stock solution is diluted to 20.0 mL, the resulting concentration is 0.05 M. Similarly, when a 10.0 mL volume of the same 0.20 M stock solution is diluted to 20.0 mL, the resulting concentration is 0.10 M.

formula for dilution: C1V1 = C2V2
where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.
C1 = 0.20 M, V1 = 5.0 mL, V2 = 20.0 mL
Let's plug these values into the formula:
(0.20 M)(5.0 mL) = C2(20.0 mL)
1.0 M mL = C2(20.0 mL)
Now, we can cancel out the mL units:
1.0 M = C2(20.0)
To solve for C2, divide both sides by 20.0:
C2 = 1.0 M / 20.0
C2 = 0.05 M
When 5.0 mL of a 0.20 M stock solution is diluted to 20.0 mL, the resulting concentration becomes 0.05 M.
Using the same formula, we can determine that when 10.0 mL of a 0.20 M stock solution is diluted to 20.0 mL, the resulting concentration is 0.10 M
C1V1 = C2V2
C1 = 0.20 M, V1 = 10.0 mL, V2 = 20.0 mL
Let's plug these values into the formula:
(0.20 M)(10.0 mL) = C2(20.0 mL)
2.0 M mL = C2(20.0 mL)
Now, we can cancel out the mL units:
2.0 M = C2(20.0)
By dividing both sides of the equation by 20.0, we can solve for C2:

C2 = 2.0 M / 20.0

This simplifies to C2 = 0.10 M.
Upon diluting a 10.0 mL portion of a 0.20 M stock solution to a total volume of 20.0 mL, the resulting concentration is determined to be 0.10 M.

The partial pressure (P) Xe = 203 mm Hg & (P) He = 648 mm Hg

According to Dalton's Law of partial pressure , Partial pressure of gas in mixture = X gas ( P total )

Where X gas is mole fraction of gas.

First calculate no. of moles & mole fraction of each gas.

We know that , No. of moles = Mass / Molar mass

therefore No. of moles of Xe ( n Xe ) = 9.81 g / ( 131.30 g /mol ) = 0.074 mol

therefore No. of moles of He ( n He ) = 0.946 g / ( 4.00 g / mol ) = 0.2365 mol

Mole fraction of Xe = Moles of Xe / Total moles of gas = n Xe / ( n Xe + n He )

therefore Mole fraction of Xe = 0.074 / ( 0.074 + 0.2365 ) = 0.2383

Mole Fraction of He = n He / ( n Xe + n He )

therefore Mole fraction of He = 0.2365 / ( 0.074 + 0.2365 ) = 0.7616

Partial pressure of Xe = 0.238 ( 851 mm Hg ) = 203 mm Hg

Partial pressure of He = 0.761 ( 851 mm Hg ) = 648 mm Hg

ANSWER : P Xe = 203 mm Hg & P He = 648 mm Hg

Leonard uses a gas stove in a poorly ventilated kitchen, the gas which could rise to dangerous levels in Leonard's kitchen is Carbon Monoxide, option B.

Carbon monoxide is a toxic, combustible gas that has no colour, flavour, or taste and is slightly less dense than air.

When carbon monoxide accumulates in your bloodstream, it causes carbon monoxide poisoning. When there is an excessive amount of carbon monoxide in the air, your body replaces the oxygen in your red blood cells with carbon monoxide. This can result in severe tissue damage or even death.

Carbon monoxide is a colourless, odourless, and tasteless gas that is created when gasoline, wood, propane, charcoal, or any fuel is burned. Improperly vented appliances and engines, particularly in a closely sealed or enclosed location, may allow lethal quantities of carbon monoxide to develop.

If you suspect that you or someone you're with has carbon monoxide poisoning, get some fresh air and seek immediate medical attention.

Answer:

Atoms are the building blocks of life (everything basically)

Explanation:

To find out how many moles of gas a container can hold, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

We know that P = 1.00 atm, V = 0.325 L, and T = 293 K. We also know that the ideal gas constant R = 8.314 J/mol·K.

We can use this information to find the number of moles n in the container:

n = (PV) / (RT)

n = (1.00 atm * 0.325 L) / (8.314 J/mol·K * 293 K)

n = 0.0094 mol

So, the container can hold 0.0094 moles of gas.

The solution is the mixture of the solute into the solvent particles. In 60 mL solution, 59.8 mL of solvent is added.

Solute and solvent are the components of a solution. They react and mix together to produce a homogenous mixture. The solute is a substance that is added to the solvent.

Solvents are substances that dissolve the added solute in them to make a homogenous solution.

Given,

Volume of Solute = 0.20 mL

Volume of Solution = 60 mL

The volume of solvent is calculated as:

Volume of solvent = Volume of solution - Volume of solute

= 60- 0.20

The most important chemical buffering system in the extracellular fluid is the bicarbonate buffering system.

The bicarbonate buffering system is the primary chemical buffering system in the extracellular fluid. It plays a crucial role in maintaining the pH balance of the body. The system involves the reversible conversion between carbon dioxide (CO2), water (H2O), and bicarbonate ions (HCO3-).

When excess acid is introduced into the extracellular fluid, it combines with bicarbonate ions to form carbonic acid (H2CO3), which can then dissociate into water and carbon dioxide. This reaction helps to remove excess hydrogen ions (H+) from the system, preventing a significant decrease in pH.

On the other hand, if the extracellular fluid becomes too alkaline, carbon dioxide reacts with water to form carbonic acid, which can then dissociate into bicarbonate ions and hydrogen ions, thus increasing the concentration of hydrogen ions and lowering the pH.

Overall, the bicarbonate buffering system acts as a vital mechanism in maintaining the acid-base balance of the extracellular fluid by adjusting the concentration of bicarbonate ions and hydrogen ions in response to changes in pH.
