You are so excited-your first summer job! You are a hot-tub maintenance assistant. You travel to homes, making sure the pH of their hot-tub water is correct (between 7 and 7.6), and adjusting and cleaning when necessary. But before you get started, you need to answer the following questions. What is pH? What do you use to test it? Why would it be important to keep the pH of hot-tub water between 7 and 7.6?

Answers

Answer 1

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 2

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.

Explanation:

Suppose you found a material in which 12.5% of the original radioactive atoms were present. If the half-life is 10years, how old is the material?

Answers

Answer:

The material is 30 years old.

Explanation:

The decay of radioactive isotopes can be modelled by the following ordinary differential equation:

[tex]\frac{dm}{dt} = -\frac{m(t)}{\tau}[/tex] (Eq. 1)

Where:

[tex]m(t)[/tex] - Current mass of the isotope, measured in grams.

[tex]\tau[/tex] - Time constant, measured in years.

[tex]\frac{dm}{dt}[/tex] - Rate of change of the isotope in time, measured in grams per year.

After some handling, we find that the solution of the differential equation is:

[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (Eq. 2)

Where:

[tex]m_{o}[/tex] - Initial mass of the isotope, measured in grams.

[tex]t[/tex] - Time, measured in years.

Now we clear time within the expression above:

[tex]t = -\tau\cdot \ln \frac{m(t)}{m_{o}}[/tex]

Besides, we determine the time constant in terms of the half-life ([tex]t_{1/2}[/tex]), measured in years:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)

If we know that [tex]t_{1/2} = 10\,yr[/tex] and [tex]\frac{m(t)}{m_{o}} = 0.125[/tex], then the age of the material is:

[tex]\tau = \frac{10\,yr}{\ln 2}[/tex]

[tex]\tau = 14.427\,yr[/tex]

[tex]t = -(14.427\,yr)\cdot \ln 0.125[/tex]

[tex]t \approx 30\,yr[/tex]

The material is 30 years old.

By the IUPAC Naming Convention followed by every chemical standards, the structure from the question is named as 4,4-dimethyl heptane.

IUPAC Stands for International Union of Pure and Applied Chemistry.This organisation issued some standards for naming any chemical components that is followed world wide.

According to the IUPAC Standards:

First of all we have to identify the longest carbon chain which is an alkane group according to this question.As a result of 7 carbon linked with single bonds it will be named heptane.Now moving to the other parts:

[tex]-CH3[/tex] is termed as methyl

As the both the methyl group( [tex]-CH3[/tex]  ) is linked with the fourth carbon the numbering is 4 for methyl.So,the IUPAC name of this compound in the image is 4,4-dimethyl heptane.

What is the chemical equation?

A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.

The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.

According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.

Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:

2N₂  +  O₂ → 2N₂O

The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.

Explanation:

Eric is investigating what happens when heat is added or removed from an object. First he places a mug of hot chocolate in this hand and records the temperature of the hot chocolate and the surface of his hand every five minutes for a total of 15 minutes. He repeats this procedure when investigating heat flow with an ice cube. Use the diagram to answer the question below. A flowchart illustration with two forward (right direction) arrows and two backward (left direction) arrows. The phrase Mug of chocolate is followed by the forward arrow A that leads to the word Hand. The word Hand is followed by the forward arrow C that leads to the phrase Ice cube. The word Ice cube is preceded by the backward arrow D that leads to the word Hand. The word Hand is preceded by a backward arrow B that leads to the phrase Mug of hot chocolate. What could Eric conclude about what happens when heat is added or removed from an object after he completed his test with the mug of hot chocolate? A. Arrow A shows the direction heat flowed because the temperature of his hand increased as heat was absorbed by his hand. B. Arrow A shows the direction heat flowed because the temperature of his hand increased as heat was released from his hand. C. Arrow B shows the direction heat flowed because the temperature of the hot chocolate changed as heat was absorbed by the mug. D. Arrow B shows the direction heat flowed because the temperature of the hot chocolate changed as heat was absorbed by his hand.

Answers

Answer:

A). Arrow A shows the direction heat flowed because the temp of his hand increased as the heat was absorbed by his hand.

Explanation:

As per the given description, Eric can conclude that when 'heat is either prepended or separated from an object after the completion of his test' as arrow A displays the direction in which the heat has flown because his hands' temperature increased after the heat was absorbed by his hand. It implies that heat is prepended when the temperature of his hand increases and vice versa when the heat is removed. Thus, option A is the correct answer.

letter A is right.

lonic bonds tend to form between two atoms with what characteristics?​

Answers

Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.

Explanation:

Ionic bonds tend to form between two atoms with a high electronegativity difference.

Explanation:

An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compounds

So, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

Answers

Answer:

D .The particles of matter are arranged in different ways for the different state.

Explanation:

The kinetic molecular theory is used to explain the forces between molecules and the energy the molecules possesses.

One of the key postulate of this theory is that;

The particles of molecules are continual state of motion. They posses kinetic energy. In gas, the particles are random and moves in a straight line motion. Liquids are less random and only slide past one another. Solids have a restricted space and the molecules are free to move about.

Therefore, we can see that the particles of matter are arranged in different ways for different state.
