The addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.

An acid-base titration is one in which an acid is added to a given volume of base in order to neutralize it.

When more of acid is added to a solution of a base than is required to neutralize it, the solution becomes acidic.

Similarly, when more base is use to neutralize an acid than is required, the solution becomes alkaline.

In the given simulation, (H3O+) is the acid while (A-) is the base.

By adding increasing the quantity of acid added, the number of H3O+ particles will increase. This will reduce the pH of the solution.

Also, the adding more base to the solution, the number of A- particles in the solution will increase. This will increase the pH of the solution.

Therefore, addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.

Answer:

205 calories.

Explanation:

According to the USDA, "Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram." 9 grams of fat at 9 calories per equals 81 calories + 6 grams of protein at 4 calories per gram which equals 24 calories + 25 grams of carbohydrate at 4 calories per gram which is equal to 100 calories.

Total that all up and you get 81 cal + 24 cal + 100 cal=205 calories.

I don't know what kind of course this is for, but if they are incredibly picky, what we refer to as "calories" are actually kilocalories, which are equal to one thousand "real" calories each. However, I'm very confident that the correct answer is 205 calories.

The sandwich will provide 205 calories.

A calorie is an energy unit. It's the quantity of heat needed to increase the temperature of one gramme of water by [tex]1^{0} C[/tex] at one atmosphere of pressure.

Its is given that, Fat = 9 g, protein = 6 g, carbohydrate = 25 g.

It is known that, fat contains 9 calories / gram , carbohydrate contains 4 calories / gram and protein contains 4 calories / gram.

Now, adding all terms.

Total calories = (9×9) +(6×4) +(25×4)

= 205 calories.

Therefore, the sandwich will provide a total of 205 calories.

Answer:

Electronnegativity

Explanation:

There are three important structural features: Hybridization, Bond angels, and Electron Geometry.

The not so important structural feature found by the number of electron rich regions is electronegativity. Hence option c is correct.

Structural feature is defined as the modeled as a directed acyclic graph (DAG), with the variable names as pathways and the variable values as nodes. The study of the construction of biological molecules is known as structural biology. Scientists study molecules in three dimensions using a range of imaging techniques to examine how they are put together, how they work, and how they interact.

Electronegativity is defined as the propensity for atoms involved in covalent bonds to draw the bonding electrons. The negatively charged electrons are drawn to the positively charged protons in the nucleus. The electronegativity or attraction will rise with the number of protons in the nucleus. Therefore, in a row of the periodic table, electronegativity rises from left to right.

Thus, the not so important structural feature found by the number of electron rich regions is electronegativity. Hence option c is correct.

Answer:

880.5

Explanation:

Express the result of adding 856.6g and 23.86g to the correct number of significant figures.

856.6 +23.86  = 856.6 + 23.9 = 880.5

The result of adding 856.6 g and 23.86 g after rounding off to correct significant figures is 856.6 + 23.9=880.5.

Significant figures are used for establishment  of a number which is presented in the form of digits. These digits give a meaningful representation  to the numbers.

The significant figures are the significant digits which convey the meaning according to the accuracy. These provide precision to the numbers and hence are called as significant numbers.There are rules for counting significant figures which are as follows:

1)All non-zero digits are significant .

2)All zeroes which occur between non-zero digits are significant.

3)All zeroes to the left and right of  a non-zero digit are not significant.

4) All zeroes on right  of decimal are significant if a non-zero number follows them.

5)All zeroes on right side of non-zero digit are significant.

The molecules of the two gases will have the same kinetic energy at room temperature.

The average kinetic energy of gaseous molecules can be calculated using the formula:

Kinetic Energy = 3/2RT, where R = constant and T = temperature in Kelvin

This means that the kinetic energy of a gaseous molecule is dependent on the temperature of the molecule only.

In other words, the molecular mass of molecules of gases has no bearing on the kinetic energy of each molecule.

The atomic and molecular interactions unveil the bulk properties of matter in our environment by ways of the fact that everything in the whole universe is made of either atoms, molecules or even ions

It has been proven practically everything in the whole universe is matter and everything which interact with matter is also matter. This explains to us the reasons why matter could be atoms, molecules or ions.

That being said, some substances (matter) is made up of atoms of elements, some made up of molecules or atoms and molecules and others ions or both. However, matter is anything which has mass and occupies space.

In conclusion, we can now conclude from the explanation above that the properties of matter are as a result of the interaction which exists between matter at the atomic and molecular level.

Answer:

see below

Explanation:

1. The temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance.

2. solid, liquid, gas

3. The forces between water molecules break, and the bonds between the atoms in water are unchanged.

4. The forces strengthen, and the molecule structure becomes more rigid.

5. The intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.

The the degree of intermolecular interaction between molecules determines the magnitude of boiling point of the substance.

During phase change, a substance moves from one state of matter to another. The temperature at which a phase change occurs is determined by the strength of the forces between molecules in the substance. The relative magnitude of intermolecular forces between molecules in different states of matter is solids > liquids > gases.

During boiling, energy is imparted to the molecules of a liquid. When this occurs, the forces between water molecules break, and the bonds between the atoms in water are unchanged.

We must recall that the molecules of a substance are in constant random motion. The average kinetic energy of molecules is proportional to temperature. As a sample of  calcium carbonate is cooled, the forces between molecules strengthen, and the molecule structure becomes more rigid.

The magnitude of intermolecular interaction affects the boiling point of a liquid. The stronger the magnitude of intermolecular interaction,the higher the boiling point. As such, ethanol having hydrogen bonds between its molecules has a higher boiling point than acetone which only posses weaker dipole - dipole interactions.

Answer:

Sound requires a medium to move through; light does not.

Sound and light are similar in that both are forms of energy that travel in waves.

Explanation:

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.

Light waves DO NOT require a medium, they travel fastest in empty space; Sound waves REQUIRE a medium, they travel fastest in dense material like solids. Sound is a longitudinal wave.

Answer:nuclear reaction

Explanation: Nuclear fusion is a type of nuclear reaction where two light nuclei collide together to form a single, heavier nucleus. Fusion results in a release of energy because the mass of the new nucleus is less than the sum of the original masses.

Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy.
