Magnesium (24.30 g) reacts with hydrogen chloride (X g) to produce hydrogen gas (2.04 g) and magnesium chloride (96.90 g). How much hydrogen chloride was used in the reaction?

Answers

Answer:

[tex]74.64\ \text{g}[/tex]

Explanation:

Reactants

Magnesium = 24.3 g

Hydrogen chloride= x g

Products

Hydrogen gas = 2.04 g

Magnesium chloride = 96.9 g

As the mass of the reactions is conserved we have

Mass of reactants = Mass of products

[tex]24.3+x=2.04+96.9\\\Rightarrow x=2.04+96.9-24.3\\\Rightarrow x=74.64\ \text{g}[/tex]

Mass of hydrogen chloride is [tex]74.64\ \text{g}[/tex].

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.

The particles in liquids and gases show random motion. What does that mean and why does it occur??

Answers

Answer:

Liquids and gases show random movements because of potential and kinetic energy.

It happens when heat is applied to the particles and they gain more potential and kinetic energy and move around faster. With gases, they have the most energy.

If anything doesnt make sense, make sure to message me

Answer:

The particles show random motion because liquid and gas particles do not have a rigid structure, unlike solid particles. They are free to go anywhere.

What is the mass of 0.0467 mol of the element sodium (Na)

Answers

Answer:

Explanation:

All periodic tables list different amounts of elemental masses. I'm going to round Sodium to 23

1 mol of sodium = 23

0.0467 mol sodium = x

Cross multiply

1*x = 0.0467 * 23

x = 1.0741 grams

You can also do it this way

The equation to find
moles(n) = m(g)/M(g.mol^-1)

Therefore if you rearrange the equation to find the mass(g) you can solve.

m = nM
m = (0.0467mol) * (22.99g.mol^-1)
m = 1.0736g

SOLVED!!

n = moles
m = grams
Molar mass = g.mol^-1 = grams per moles

*= multiplying

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.

1. Hermione is trying to replicate the Polyjuice Potion that they created in their second year at Hogwarts. The problem is that she doesn’t have the exact ingredients that she needsandshe is trying to substitute imitation bat wings instead of real bat wings. She knows that they are not as strong as the original so she is making three batches in the same cauldrons over the same fire so she can test which amount of imitation bat wing will work. The potion will turn green when the correct amount is added.

Test (independent) Variable: ___________________________________

Result (dependent) Variable: _______________________________________________

Constants: ____________________________________________

Answers

Answer:

A) Test(independent) variable is bat wings.

B) Result (dependent) Variable is the Polyjuice Potion.

C) Cauldrons and fire

Explanation:

A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.

Now, in this experiment, what is being tested is are the bat wings.. Thus;

Test(independent) variable is bat wings.

B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.

Thus, Result (dependent) Variable is the Polyjuice Potion.

C) The constants are things that don't change with respect to any of the other variables. In this case, they are; cauldrons and fire

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.
