Ethanol is a product of fermentation.

Ethanol fermentation, also known as alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

A chemist dissolves 716.mg of pure potassium hydroxide in enough water to make up 130.mL of solution. Calculate the pH of the so

Natasha_Volkova [10]

<u>Answer:</u> The pH of the solution is 13.0

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

Given mass of KOH = 716. mg = 0.716 g (Conversion factor: 1 g = 1000 mg)

Molar mass of KOH = 56 g/mol

Volume of solution = 130 mL

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{0.716\times 1000}{56g/mol\times 130}\\\\\text{Molarity of solution}=0.098M$

1 mole of KOH produces 1 mole of hydroxide ions and 1 mole of potassium ions

To calculate hydroxide ion concentration of the solution, we use the equation:

$pOH=-\log[OH^-]$

We are given:

[tex[[OH^-]=0.098M[/tex]

Putting values in above equation, we get:

$pOH=-\log(0.098)\\\\pOH=1.00$

To calculate the pH of the solution, we use the equation:

pOH + pH = 14

So, pH = 14 - 1.00 = 13.0

Hence, the pH of the solution is 13.0

Which has greater Mass 10 mL of steel (Density

masya89 [10]

The steel would have a mass of 78g and the mercury would have a mass of 68g. So the Steel has greater mass.

Explained: This picture I also attached explains that whenever you have an equation dealing with density and volume alone, you will multiply the 2 together to get your answer for mass. And when your dealing with mass and rather volume or density you will divide the mass by whatever the volume or density is. For example if you need to find the density of an object that is 25g and 14ml you will write out this equation 25g/14ml= 1.78 g/ml. And if you need to find the mass of an object that is 27ml and 14g/ml you will write an equation like this 27mlX14g/ml= 378g. I hope this helps with your understanding.

A particular kind of Spanish orange is completely fat free. If one of the oranges has 40 Calories total and a test shows that it

LenaWriter [7]

Answer:

9 grams of Carbohydrates

Explanation:

The energies contained by each class of these compounds are as;

(i) Fats:

1 grams of Fat contains 9 Calories

(ii) Proteins:

1 grams of Proteins have 4 Calories

(iii) Carbohydrates:

1 grams of Carbohydrates contains 4 Calories

(iv) Vitamins and Minerals:

Vitamins and Minerals have no Calories

Solution:

As 1 gram of Protein Contains 4 Calories so, we will subtract 4 Calories from the total Calories contained by the Juice as,

Calories by Carbohydrates = Total Calories - Calories by Protein

Calories by Carbohydrates = 40 - 4

Calories by Carbohydrates = 36 Calories.

Hence,

As,

4 Calories were contained by = 1 gram of Carbohydrate

So,

36 Calories will be contained by = X grams of Carbohydrates

Solving for X,

X = 36 Calories × 1 gram / 4 Calories

X = 9 grams of Carbohydrates
