Answer: well i guess we can say that  is a scale used to specify the acidity or basicity of an aqueous solution and it is important to keep ph of hot tub water between 7 and 7.6 because if it is not balanced the water  can negatively affect your tub.

Explanation:

pH is an extremely important chemical level to maintain in your spa's water chemistry. A high pH or a low pH will spell trouble for you and your spa. On the pH scale, a reading of 7.4-7.6 indicates perfectly balanced pH. Any number lower than 7.4 means that your water is now considered “acidic”.

Answer:

pH is a scale to measure the acidity or basicity of a substance such as water, it would be important to keep the pH of hot-tub water between 7 and 7.6 because if the acidity is too high, the walls of the hot-tub may be damaged, and if the pH is too low, the heating thing may get damaged.

Answer:

Vascular plants are successful due to better transportation for water, nutrients and reproduction.

Explanation:

I got it right at school and hope this helps you learn to STUDY.jk

According to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Plants with seeds, including flowering plants and conifers, produce pollen grains as a component of their reproductive process. They are often carried by wind or pollinators, such as bees, to the female reproductive organs of the same or different plant species, where they can fertilize female gametes (egg cells) and begin the development of seeds.

They carry the male gametes (sperm cells) of the plant. Many plant species depend on pollen grains for successful reproduction, and these grains have evolved a variety of forms, sizes, and surface features that make them easier to disperse and be recognized by pollinators.

Therefore, according to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Answer:

We refer to the atoms of the same element with different numbers of neutrons as "isotopes". While the particular isotope involved does not affect how an atom will react chemically, it does determine how the atom will behave in nuclear reactions.

Explanation:

Answer:

The # of neutrons equal the number of electrons and protons.

Explanation:

Look what I wrote above.

Answer: Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

Explanation:

The statement which best describes how scientists arrived at the current understanding of electromagnetic energy is (C)  Scientists debated the theories with each other and compared the theories with scientific observations. hence option (C) is correct.

Electromagnetic energy consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy.

It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.

A unification criterion holds that a theory is empirically successful, and thus confirmed, to the ex- tent that it predicts or explains a large number of empirical results by ap- pealing to only a relatively small number of basic principles.

Answer:

The atomic mass is 101.

Explanation:

Protons and neutrons are the only particles that contribute to mass. Electrons do have a mass, but it's so miniscule and insignificant that it doesn't contribute to the mass of an atom. In every instance of calculating atomic mass, add the number of protons to the number of neutrons.

Therefore,

44 + 57 = 101

number of protons + number of neutrons = atomic mass

Also, there can never be a negative amount of protons or neutrons, so if you get a negative number, there's something wrong.

Bonus Information:

Don't confuse mass with charge! As it says in its name, neutrons are neutral or have no charge. Protons (+) and electrons (-) are the only particles that have a charge, so calculating that would be different.

If you were calculating the atomic charge with the same numbers, your answer would be:

44 - 42 = 2

Charge = +2

What To Remember:

M = p + n

C = p - e

C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:

[tex]\frac{P}{T} =k[/tex]

Studying two different states, an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.

Finally, the pressure will increase by a factor less than three.

Standard International system is a system is used to measure physical properties.

The International System of Units (SI), is commonly known as the metric system. This system is used as the international standard for measurement. Most scientists use the International System of Units which is also known as the metric system in order to measure physical properties of elements. The metric system is a system of measurement that uses meter as base units of length (distance), liter for volume, and , and gram for weight or mass. We use units that are derived from the metric units in order to measure smaller or larger quantities.

So we can conclude that Standard International system is a system is used to measure physical properties.

Answer:

D. All of the above

Explanation:

Molecules, ions, and pure elements might be included in a chemical reaction. Therefore, option (d) is correct.

A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.

The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.

Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.

Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.
