how much muriatic acid to lower alkalinity in pool

Answer:

I don't know what your asking

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 15 g

volume = 3 mL

We have

[tex]density = \frac{15}{3} = 5 \\ [/tex]

We have the final answer as

Hope this helps you.

Answer:

Its C

Explanation:

The law of conservation of mass says no atoms can be created or destroyed just rearranged so the mass at the beginning before the reaction would stay the same after it

Considering the Law of Conservation of Matter, the correct answer is the third option: the total mass of the products will be the same and has a value of 58.44 amu.

The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "the mass is not created or destroyed, only transformed."

This means that the reagents interact with each other and form new products with physical and chemical properties different from those of the reagents because the atoms of the substances are ordered differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the quantities of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends.

In other words, then the mass before the chemical reaction is equal to the mass after the reaction.

So, in this case, if the total mass of the reactants is 58.44 amu, the total mass of the products will be the same and has a value of 58.44 amu.

Finally, the correct answer is the third option: the total mass of the products will be the same and has a value of 58.44 amu.

We know that the electron clouds of two atoms overlapping is a bond, because that signifies that the electrons are being shared in a bond.

So, I'm going to go through some definitions of these different types of bonds, because they have very specific circumstances.

A hydrogen bond is a bond between an electronegative atom and a hydrogen molecule (which is not what this question says, this isn't stated anywhere).

A dipole is a difference in electron density on two different atoms (so this isn't even close to what the question is stating, a dipole is not even a bond)

An ionic bond is an unequal sharing of electrons between two atoms (because the question doesn't state this specific fact, then it can't be this option).

By process of elimination, we know the answer is covalent bond, but just in case, we can also look at the definition of a covalent bond: a bond that involves the sharing of electrons between atoms.

That is exactly what the question is asking for! Therefore, your answer is d. covalent bond

Answer:

Proxies enable scientists to recreate climate conditions in different parts of history.

Explanation:

Proxies are characteristics of the weather in a certain period of time that have been preserved for different weather measurements like temperature, humidity, wind direction, and amounts of precipitation. The reason scientists create proxies because it "enables them to recreate climate conditions from different parts of time to have a better understanding on what weather was like during that time period."

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 1892.6 g

volume = 200 mL

We have

[tex]density = \frac{1892.6}{200} \\ = 9.463[/tex]

Answer:

false

Explanation:

The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly

Explanation:

Answer:

1.heterogeneous mixture

2.element

3.compound

4.homogeneous mixture

Explanation:

The correct pairs are:

A cloud, which consist of small water droplets - Heterogeneous mixture

Distributed throughout the air

helium, a gas composed of identical atoms - Element

Rubbing alcohol, a liquid composed of chemically bonded - Compound

Carbon, Oxygen, and Hydrogen atoms

sugar thoroughly dissolved in water - Homogenous mixture.

In Heterogenous mixture, the composition of the mixture is not uniform. In Homogenous mixture, the composition is uniform throughout. Element is the combination of same atoms. Compound contains two or more elements.

Therefore, the correct pairs are,

A cloud, which consist of small water droplets - Heterogeneous mixture

Distributed throughout the air

helium, a gas composed of identical atoms - Element

Rubbing alcohol, a liquid composed of chemically bonded - Compound

Carbon, Oxygen, and Hydrogen atoms

sugar thoroughly dissolved in water - Homogenous mixture.

Streak

Explanation:

Streak is the microscopic remains of minerals in powder form after being rubbed with porcelain plates. The streaks do not have orderly arranged lattice structure or unit cells.

They are randomly arranged and microscopic size powders. The streak of minerals cannot be distinguished easily as it mostly appears similar for all minerals.

Thus, among the given options streak is one in the property of minerals. We can rely upon streaks as it cannot be easily affected by impurities.
