45.0 mL of a Naoh solution is titrated with 0.12 M HCl. If 29.6 mL is required for neutralization,what is the concentration of the NaOH solution?

Answers

Answer 1
Answer:

Answer:

M(NaOH) = 0.0789 M

Explanation:

NaOH + HCl ---> NaCl + H2O

M(NaOH)*V(NaOH) =M(HCl)*V(HCl)

M(NaOH) *45.0 mL (NaOH) = 0.12 M(HCl) * 29.6 mL(HCl)

M(NaOH) = 0.12*29.6/45.0  = 0.0789 M

Which of the following did Antoine Lavoisier incorrectly characterize as matter? light silicone dioxide mercury

Answers

AntoineLavoisier incorrectly characterize light as matter. The correct option is A.

Who was Antoine Lavoisier?

He is best known for discovering the role of oxygen in combustion. Antoine Lavoisier was a Frenchchemist who discovered that air is the source of combustion and acidity. He developed the metric system and debunked the phlogistontheory.

A diligent researcher, Antoine-Laurent Lavoisier, fundamentally changed chemistry. Among his many accomplishments, he established the law of conservation of mass, discovered that combustion and respiration are caused by chemical reactions with what he called "oxygen," and helped systematize chemicalnomenclature.

An element, according to Lavoisier, is a chemicalsubstance that cannot be decomposed using current analyticalmethods.

Mendeleev defined an element as a substance made up of atoms with the same atomic weight. Light is incorrectly described as matter by AntoineLavoisier.

Thus, the correct option is A.

Suppose you are digging a hole in the ground. You notice that the soil is in two layers. Each layer has particles of different sizes. You observe the soil closely and find that the bottom layer is made up mostly of sand and the top layer is made up mostly of clay. What do you think caused the soil to have two different layers?

In liters, occupied by 2.18 miles of N2 gas

Answers

Answer:

The volume occupied by 2.18 moles of N_(2) is 48.832L

Explanation:

The volume occupied by 1 mole of N_(2) is 22.4 L

The volume occupied by 1 mole of any gas is 22.4 L

The number of moles of N_(2) = 2.18 moles

The volume occupied by 2.18 moles of N_(2):

Volume=2.18*22.4=48.832L

Hence, the volume occupied by 2.18 moles of N_(2) is 48.832L

Which of these is a mixture?a. oxygen
b. air
c. carbon dioxide
d. carbon

Answers

Answer is: b. air.

Homogeneous mixture (air) has the same proporties of its components (nitrogen, oxygen, carbon dioxide) throughout any given sample.

Together, nitrogen (N₂) and oxygen (O₂) by volume account for 99,03% of the gases composing the dry air in the lower atmosphere.

Volume of nitrogen in air is 78,08%.

Volume of oxygen in air is 20,95%.

Together: 78,08% + 20,95% = 99,03%.

Why is it important that the polymer membrane in a PEM fuel cell allows only protons to move through it? It forces the electrons to move through an external circuit, where they can do work. It prevents the protons from reacting with the compounds in the rest of the fuel cell. It allows the protons to build up potential energy and release more energy when they react with oxygen. It keeps the electrons from corroding the interior of the PEM fuel cell.
