Answers

The use of the pH scale and litmus paper are the ways which can determine whether the solution is an acid or base.

How pH scale and litmus paper tell about acidic and basic solution?

The pH scale is the way which determine the acidic or basic nature of a solution. If the pH of a solution is less than 7, it is considered as acidic. If the pH is 7, the solution is neutral and if the pH is greater than 7,the solution is basic.

While on the other hand, litmus paper also tells us about acidic and basic nature of solution. if the litmus paper turns red, it means the solution is acidic whereas if the litmus paper turns blue it means basic.

Argon gas has a temperature of 180°C at a pressure of 900 torr. If the gas is heated to 370°C, what is the new pressure of Argon gas in atmospheres (atm)? (Hint: 1 atm = 760 torr)

Answers

Based on the calculations, the final pressure of this gas sample at 370°C is equal to 2.66 atm..

Given the following data:

Initial temperature = 180°C.

Final temperature = 370°C.

Initial pressure = 900 torr.

Conversion:

760 torr = 1 atm.

900 torr = 1.29 atm.

How to determine the final pressure.

In order to calculate the final pressure of an ideal gas at constant volume, we would apply Gay Lussac's law.

Mathematically, Gay Lussac's law is given by this formula;

[tex]P\;\alpha \;T\\\\P=kT[/tex]

Where:

P is the pressure.T is the temperature.k is the constant of proportionality.

Substituting the given parameters into the formula, we have;

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2} \\\\\frac{1.29}{180} =\frac{P_2}{370} \\\\0.0072 =\frac{P_2}{370}\\\\P_2 = 0.0072 \times 370[/tex]

Final pressure = 2.66 atm.

Assume you added 40.0 mL of Vitamin C stock solution instead of 25.0 mL when preparing Solution. How would this affect the reaction rate?

Answers

The reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

What happen when the vitamin C is added in lower amount?

If you added 40.0 mL of Vitamin C stock solution instead of 25.0 mL when preparing Solution, the reaction rate is affected because of the lower amount of reactant for the chemical reaction. If the reactants are present in larger amount then the products are also produced in large concentration.

So we can conclude that the reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

Answers

Answer:

FalseTrueTrueFalseFalseTrueFalseTrueTrueTrue

Explanation:

Sucrose is a polar carbohydrate. The negative and positive regions on the polar sucrose molecules are attracted by the polar water molecules, causing sucrose to dissolve in water. A polar substance like sucrose cannot be dissolved by a nonpolar substance like mineral oil.Because hydrogen bonding gives ethanol a stronger intermolecular force than acetone, ethanol has a higher boiling point than acetone. Because vapor pressure is proportional to boiling point in an indirect manner, acetone has a higher vapor pressure at 25° than ethanol.The Ostart text, O, end text atom hogs electrons and keeps them away from the Hstart text, H, end text atoms because oxygen is more electronegative (electron-hungry). This results in a partial negative charge on the oxygen end of the water molecule and a partial positive charge on the hydrogen end.The stability of DNA double-helical structures is aided by aromatic stacking and hydrogen bonding between nucleobases, which are two of the most important interactions. Hydrogen bonds are noncovalent interactions that are weak, yet the enormous number of hydrogen bonds between complementary base pairs in a DNA double helix combine to endow the structure with a lot of stability.'Boron, silicon, germanium, arsenic, antimony, and tellurium are metalloids. These elements resemble metals but do not conduct electricity as effectively as metals, making them semiconductors.The strength of a liquid's intermolecular forces determines its vapor pressure. The vapor pressure of a liquid with weak intermolecular interactions is higher. The vapor pressure of a liquid with higher intermolecular interactions is lower than that of a liquid with less intermolecular forces.The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point.When an ion interacts with a non-polar molecule, it causes an ion-induced dipole force. The charge of the ion produces a distortion of the electron cloud in the non-polar molecule, generating a brief partial charge, similar to a dipole-induced dipole force.water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil.

how many CO grans are produced from 1.80 mol of sulfur dioxide2

Mols become useful when we learn that, for any element on the periodic table, 6.02 X 10^^23 atoms of that element have a mass equal to the atomic mass in grams. So, on the periodic table carbon has an atomic mass of 12.011. That means: 12.011 grams of carbon is made up of 6.02 X 10^^23 atoms.

The above question is tricky.

If the question considers 1 molecule of SO2 as a particle, then the answer is 1.80 * 6.02 X 10^^23

If the question considers the S as one particle, and the O2 as 2 more particles, then the answer is: 3 * 1.8 * 6.02 X 10^^23.

Answer:

Explanation:

alculate the (H3O+) for a solution whose pH is 6.79

Note: blank 1 should have three significant figures

The answer is: Blank 1 X 10^Blank 2

The pH of a solution is the negative logarithm of H₃O⁺ ion concentration.The concentration of H₃O⁺ ions in a solution with a pH of 6.79 is 1.6 × 10⁻⁷M.

What is pH ?

pH of a solution is the measure of its acidity or basicity. Mathematically it is the negative logarithm of its  H₃O⁺ ion concentration. A solution with a pH of 7 is neutral.

The solution with a pH below 7 is acidic and above 7 is basic. Thus, the higher H+ ion concentration, then the pH will be lower and more acidic the solution.

It is given that the pH of the solution is 6.79. The concentration of  H₃O⁺ ions in the solution is calculated is calculated as follows:

pH   = -log ( H₃O⁺)

6.79 = -log( H₃O⁺

[ H₃O⁺] = antilog (-6.79)

             =  1.6 × 10⁻⁷M

Hence, the  hydronium ion H₃O⁺ ion concentration of the solution of pH 6.79 is  1.6 × 10⁻⁷M.

Taking into account the definition of molarity,  the concentration of Na₃PO₄ in solution is 0.192[tex]\frac{moles}{lliter}[/tex].

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{lliter}[/tex].

Concentration of Na₃PO₄ in solution

Being the molar mass of Na₃PO₄ 163.94 g/mole, that is, the amount of mass that a substance contains in one mole, the amount of moles that contains 23.6 g sample of Na₃PO₄ is calculated as:

[tex]23.6 gramsx\frac{1 mole}{163.94 grams} = 0.144 moles[/tex]

Then you know:

number of moles= 0.144 molesvolume= 750 mL= 0.750 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

[tex]Molarity=\frac{0.144 moles}{0.750 L}[/tex]

Solving:

Molarity= 0.192[tex]\frac{moles}{lliter}[/tex]

Finally, the concentration of Na₃PO₄ in solution is 0.192[tex]\frac{moles}{lliter}[/tex].

Option B

As per the given balanced reaction, 0.75 moles of aluminum metal requires 0.56 moles of oxygen gas for completely reaction. One mole of oxygen gas is 32 g. Then, mass of 0.56 moles is 18 g.

What is aluminum oxide ?

Metals and metal like elements such as aluminum Al are more reactive towards atmospheric oxygen and forms their oxide layers in the metallic surface.

Al₂O₃ is an essential mineral of aluminum formed by the reaction with oxygen as given in the balanced chemical equation. As per this equation, 4 moles of Al requires 3 moles of oxygen for complete reaction.

The number of moles of oxygen required by 0.75 moles of Al is:

(0.75 × 3) /4 = 0.56 moles.

one mole of oxygen weighs 32 g/mol.

mass of 0.56 moles of O₂ = 32 × 0.56 = 18 g.
