Calculate the number of moles in 7g of nitrogen gas​

Answers

Answer:

0.2498mol[tex]N_{2}[/tex]

Explanation:

7gN2 x [tex]\frac{1 mol}{2(14.01) g}[/tex]

=0.2498mol N2

Nitrogen gas has the formula [tex]N_{2}[/tex] so therefore that means you would have to multiply the mass in the molar by 2. To solve for the number of moles you need to cancel out the grams, you do this by using the molar mass of nitrgoen gas. You get the value on in the denominator from the periodic table (atomic mass of element). The grams will cancel out, leaving you with the number of moles when you divide 7/2(14.01).

Mitochondria are found within: A) All prokaryotic cells B) A cell's plasma membrane C) A cell's nucleus D) Eukaryotic cells E) None of these answers are correct

Answers

Answer:

The correct answer is - D) Eukaryotic cells.

Explanation:

The mitochondrion is found in all eukaryotic organisms with the exception of a few. It is a double-membrane-bound organelle within the cytoplasm of the cell that takes in nutrients, breaks them down, and creates energy that makes it the powerhouse of the cell.

It turns the chemical energy from nutrients in the cell to generate energy in a form usable to the host cell which is ATP. Prokaryotic cells lack mitochondria and other double membrane-bound organelles and it s found outside of the nucleus in the eukaryotic cells.

of the meter might be the most appropriate mea-

surement.

a. the distance between Chicago and Saint Louis

b. the size of your bedroom

c. the dimensions of this textbook

d. the thickness of a hair

Answers

Answer:

A) Km

B) m

C) cm

D) mm

Explanation:

A) The distance between Chicago and Saint Louis is quite a distance and would be best presented in the largest multiple of the SI unit of length.

For example if the distance is 500000 m, it's a bit bogus to write, so we can simplify by writing in terms of 10^(-3) m which is in km.

Thus, we can write as 500000 × 10^(-3) km = 500 km

B) By standard measurement, the size of a bedroom is usually: 3.6 m × 3.6 m.

This not complex to write and can be kept as it is in metres.

C) The average dimension of a textbook is around 0.25 m by 0.2 m.

Let's get rid of the decimal by converting to terms of 10² m which is expressed as cm.

Thus, dimension is now: (0.25 × 10²) by (0.2 × 10²) = 25 cm by 20 cm

D) Average thickness of a hair in metres is 8 × 10^(-5) m.

Now this is a bit long. So we can express is in terms of 10^(3) m which is an expression denoted by millimeter (mm).

Thus, thickness is 8 × 10^(-5) × 10³ = 0.08 mm

Answer:

B. Molecules of different types of atoms that are not attracted to each other.

Explanation:

On a broad basis, matter can be subdivided into pure or distinct substances and impure substances (mixtures);

Pure substances are distinct substances having the following properties:

All parts are the same throughout Composition is definite They cannot easily be separated or broken down into simpler substances by physical means. Separation by physical methods is not easy. They have a unique set of physical properties.

From this criteria, we see that the second choice is nullified. This is because pure substances have their molecules attracted to each other.

What is satellite?

Any object that circles a planet in a curved route is considered a satellite. There are several man-made (manufactured) satellites, most of which are closer to Earth than the moon, which is Earth's original natural satellite.

We must revisit our buddy Newton in order to comprehend why satellites move in this manner. Gravity, according to Newton, is a force that unites all of the universe's objects. Moon phases and moon placements have a role in determining this. The only major factor affecting the Moon's phase is where it is in relation to Earth and the Sun.

What volume of a 0.0250 M KCN solution contains 8.84×10−3 mol of KCN?

Express the volume to three significant figures and include the appropriate units.

Answers

Answer:

0.354L

Explanation:

Given parameters:

Molarity of KCN  = 0.025M

Number of moles  = 8.84 x 10⁻³mol

Unknown:

Volume of KCN  = ?

Solution:

The molarity of a substance is expressed as;

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

 Volume of KCN   = [tex]\frac{number of moles }{molarity}[/tex]

Now insert the parameters and solve;

  Volume of KCN  = [tex]\frac{0.00884}{0.025}[/tex]   = 0.354L

Can sedimentation and decantation be used for all types of mixtures? Explain
Is there a relationship between the mass of an object and the rate of settling? Explain.

Answers

Explanation:

1. Sedimentation and decantation cannot be used for all types of mixtures.

Decantation is a separation technique in which is used to separate immiscible liquids or mixtures containing liquid and solids within them.

In decantation, gravity is used to bring the denser materials to settle at the bottom.

For homogenous mixtures, it is not possible to use decantation. A solution of sugar and water will not decant.

2. Yes, mass of an object reduces the settling time of such object in a mixture.

The higher the mass, the faster the rate of settling. Also, as we know, mass is directly proportional to density. A body with a high density will settle faster in solution.

A bottle has a capacity of 1.2 liters. If the density of ether is 0.74 g/mL, what mass of ether can the bottle hold?

Answers

Answer:

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate as follows:

Volume = 60.0 g ( 1 mL / 0.70 g ) = 85.71 mL

Therefore, the correct answer is option B.

Explanation:

888 grams is a mass of ether that the bottle can hold.

Explanation:

The density of the substance is defined as a mass of substance present in the unit volume of the substance.

[tex]Density=\frac{Mass}{Volume}[/tex]

Given:

A bottle with a capacity of 1.2 Liters.

The density of ether = 0.74 g/mL

To find:

The mass of ether hold by a given bottle.

Solution:

The volume of bottle = V = 1.2 L

[tex]1 L = 1000 mL\\V = 1.2 L=1.2\times 1000 mL= 1200 mL[/tex]

The density of the ether = d = 0.74 g/mL

The mass of ether that bottle can hold = m

Volume of ether required = Volume of bottle = V = 1200 mL

Using the formula of density:

[tex]d=\frac{m}{V}\\0.74 g/mL=\frac{m}{1200 mL}\\m=0.74 g/mL\times 1200 mL= 888 g[/tex]

888 grams is a mass of ether that the bottle can hold.
