Answer:

D

Explanation:

Gases have low densities. Density is the mass of an object divided by its volume. Mass of gases are quite small. Since the mass is related to mass of the particles itself. However the volume is great since the gases are far apart due to how weak the forces of attraction are ( gases take the shape of the container which means they take up a good bit of space which means greater volume). A small mass divided by a large volume gives a small value (small density).

Answer:

Answer:

AB = 17 cm

Explanation:

NOTE: This is a mathematics question. Nevertheless, the answer to the question is given below

Please see attached photo for diagram.

The length of AB can be obtained as follow:

Angle A = 54°

Adjacent = 10 cm

Hypothenus = AB =?

Using the Cos ratio, we can simply obtain the length of AB as follow:

Cos A = Adjacent /

Cos 54 = 10 / AB

0.5879 = 10 /AB

Cross multiply

0.5879 × AB = 10

Divide both side by 0.5878

AB = 10 / 0.5878

AB = 17 cm

Answer: In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

Answer:

c. main energy level of an electron

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are considered to be the building blocks of matter and as such defines or determines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these includes; protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

The principal quantum number, denoted by n, represents the main or overall energy level of an electron.

Basically, this property of an electron determines its energy level, as well as its distance from the nucleus of an atom of any chemical element. Also, as the distance of each orbital from the nucleus increases, the energy level increases respectively. Thus, sets of orbitals having the same principal quantum number (n) are generally referred to as an electron shell.

Answer:

Answer: A. the outer core is more dense and farther from the surface than the mantle

Explanation: There are two mantle‘s. But both of them are closer to the surface than the outer core. the outer core is the liquid layer outside of the inner core. The mantle is the next layer after the outer core. It goes: inner core, outer core, stiffer mantle, asthenosphere, ridged mantle, then the earth’s crust.

Answer:

You must change the size of each ingredient by the size of the product. Let's say my recipe calls for 1 bag of flower and 2 eggs. I want to double the amount of product that I make, so I must multiply each of my ingredients by 2. I would now use 2 bags of flower and 4 eggs.

Answer:

Smashing the cube into pieces

Explanation:

The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.

The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.

The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.

It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.

The amount of reactants, the temperature, and the catalyst all influence the reaction rate.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.

The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.

Thus, C is the correct answer.

Answer:

Explanation:

Na₂S₂O₃ + 4Cl₂ + 5H₂O → 2NaHSO₄ + 8HCl.

                4 moles                               8 moles

4 moles of Cl₂ forms 8 moles of HCl

.25 moles of Cl₂ forms 8 x .25 / 4 moles of HCl

HCl formed = .50 moles .

E is the answer .
