Answer:

Explanation:

To find the [H3O+] of the solution, we can use the fact that HBr is a strong acid and completely dissociates in water. Therefore, the concentration of H3O+ is equal to the molar concentration of HBr:

[H3O+] = 0.0085 M

To find the [OH-], we can use the equation:

Kw = [H3O+][OH-]

Where Kw is the ion product constant for water, which has a value of 1.0 x 10^-14 at 25°C.

Rearranging the equation to solve for [OH-], we get:

[OH-] = Kw / [H3O+]

[OH-] = (1.0 x 10^-14) / (0.0085)

[OH-] = 1.176 x 10^-12 M

To find the pH of the solution, we can use the equation:

pH = -log[H3O+]

pH = -log(0.0085)

pH = 2.07

Therefore, the [H3O+] of the solution is 0.0085 M, the [OH-] is 1.176 x 10^-12 M, and the pH is 2.07.

Answer: When we go for a run we are using chemical energy in our bodies to produce movement (kinetic energy), which in turn converts to warmth (thermal energy).

The properties of all of these material vary from each other. Paper, cardboard and plastic are insulators and metals and conductors. Each of them has different physical properties.

The physical properties of a substance include properties which changes its physical structure, size, shape, phase etc. Solubility, conductivity, resistance etc. are also physical properties.

Here, paper, cupboard and plastic are insulators and they does not conduct electricity. Whereas, metals are very good conductors and they have wide range of applications in optoelectronic devices.

Each of these materials has different melting temperature and different uses. Their density also vary significantly. The paper is the less dense one here and metals are denser.

As I'm Not % Sure I Can Say C & D don't seem Right, Leaving A & B Having Me to Think the Answer is A (Hope I'm Right Good-Luck)

Explanation:

Answer:  Mountains block the winds that bring rain clouds.

Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences

Explanation:

their genetics come from the same two parents so if their genetics looked different it would mean that a offspring wasnt one of the parents.

To solve this, we must know each and every concept behind reproduction. Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.

The process through which organisms duplicate themselves is known as reproduction. In general, reproduction is among the most essential notions in biology: it involves creating a replica, a likeness, and so ensuring the survival of species.

Their genetics are derived from the exact two parents, thus if their genetics differed, it meant that an offspring was not one of the mom and dad. "All the offspring of a set of parents have identical genes"  best describes this kind of reproduction.

Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.

Explanation:

Based on evidence from Sim, when two substances were combined they did not change into different substances.

Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.

They just combine together and form a new substance.

Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.

The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.

Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.

If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.

It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

Answer:

The regrouping of the two systems affects the components because they either don't work together or others

Explanation:

The regrouping of two systems affects the components, boundaries, and processes of the new larger system by systematic influences of each organ of the system with respect to its function.

The cardiopulmonary system may be defined as a type of organ system that comprises the respiratory system and the cardiovascular system. It includes the heart and the blood vessels and moves blood throughout the body.

This system in the body of an individual performs functions like the delivery of oxygen and nutrients from each cell to tissues specifically.

When two systems are regrouped together, each performs its own functions systematically under the influence of the other. They have defined boundaries, components, specific actions, enzymes, etc. in their respective positions.

Their boundaries are never merged, their function never interchanged, and their components never delocalized

Therefore, systematic influences of each organ of the system with respect to its function is the process that occurs during the regrouping of two systems.

The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which natural conditions that influence the variation are selected for observation.

Answer:Melting.

Freezing.

Evaporation.

Condensation.

Sublimation.

Explanation:

Answer: Examples for the five transformations previously given.

For the first four, we encounter common examples in everyday life, all to do with water:

Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.

Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.

Condensation - gas to liquid, e.g. water vapor (gas) to liquid -  water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation  in the atmosphere.

Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer

While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life.  Carbon dioxide however is a more common example.

Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.
