Explanation:

The biggest change in the body caused by regular exercise is to muscle tissue. ... At the cellular level, exercise triggers the release of substances that dilate the blood vessels in the muscle, letting in more oxygen, says Prof Bradford. These are short-term effects, but deeper changes come with regular exercise.

Exercising causes changes in our body because we're working our muscles so there's more going on with us compared to when we're just laying down. We need more oxygen to go to our muscles so we breathe harder and more rapidly. Our heart also beats faster because it needs to pump more blood to the muscles that are being worked.

Answer:

Air pollution can also cause headaches, dizziness, and nausea. ... Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs.

If an anhydrous Cupric Perchlorate weighs 262.447g/mol initially and weighs 370.540 g/mol after sitting on the bench to absorb water from the air, the number of water molecules absorbed would be 6 moles.

First, let us calculate the amount of water gained during the course of staying on the bench:

Water gained = weight after gaining water - initial weight

                       =  370.540 - 262.447

                        = 108.093g/mole

The total amount of water gained per mol is 108.093. Each water molecule weighs 18.015 g/mole. Thus, the total number of water molecules that will sum up to 108.093 would be:

                         108.093/18.015 = 6 moles

In other words, the number of water molecules absorbed by the Cupric Perchlorate is 6 moles.

Answer:

different from the number of their neutrons

Explanation:

They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.

Answer:

B

Explanation:

equilibrium happens when two things are in complete balance and thermal is in reference to heat so two things are in thermal equilibrium once they have the same temperature.

The option which indicates that two objects are in thermal equilibrium is the objects that have the same temperature. Thus, the correct option for this question is B.

Thermal equilibrium may be defined as a state of a system in which all the parts of the system occupy the same temperature. Two or more objects are in thermal equilibrium if there is no net flow of thermal energy or heat between them when they are considerably connected by a path permeable to heat.

The mechanism of thermal equilibrium occurs when a cup of hot coffee is put on the table and after a short period of time, the temperature of the coffee is the same as the surrounding temperature. So, this represents an example of thermal equilibrium.

Therefore, the correct option for this question is B.

Answer:

Humans have five basic senses: touch, sight, hearing, smell and taste. The sensing organs associated with each sense send information to the brain to help us understand and perceive the world around us.

Explanation:

-How do the senses work? Your brain collects information, like smells and sounds, through your five senses: sight, hearing, touch, taste, and smell. Each of your five senses has its own special sensor. Each sensor collects information about your surroundings and sends it to the brain.

-Why is it important? The five senses, sight, taste, touch, hearing and smell all collect information about our environment that are interpreted by the brain. We respond almost automatically to most sensory information. Such response is important for survival in our environment.

Answer:

It emits energy since to move from a higher energy level to a lower energy level or ground state, it must lose energy.

Adhesion is the attraction of molecules of one kind for molecules of a different kind... water is adhesive because the water molecules are attracted to the straw and therefore adhere to it. Thus, adhesive forces are important for sustaining life. This is because of these forces, water can flow up from the roots to the tops of plants to feed the plant, allowing it to move against gravity through plant cells. Another example of why its important that water is adhesive is the movement of water to the tops of trees and the drainage of tears from tear ducts in the corners of your eyes. Or how water droplets stick to the end of the pine needles. These are all examples of adhesion.

Ammonia and Hydrogen Chloride.

Explanation:

Assuming this is what you're referring to, Ammonia (NH3) and Hydrogen Chloride(NCI3). The concentrated ammonia (NH3) is placed on a pad in one end of a tube and hydrochloric acid (NCI3) on a pad at the other. Shortly after the gases will begin diffusing far enough to meet, a ring of solid ammonium chloride (NH4Cl) will be formed.

Answer:

The change in energy for a chemical reaction has to do with the potential energy of the electrons. The change in energy for a nuclear reaction has to do with the potential energy of the nucleus. The change in energy for a nuclear change is many orders of magnitude larger than for a chemical change.

The statement that describes both nuclear and chemical changes occur is "potential energy."

Nuclear reactions include a change in the nucleus of an atom, which usually results in the production of a different element. Chemical reactions, on the other hand, require just electron rearrangement and no changes in nuclei.

A nuclear reaction is any reaction that causes the nucleus of an atom to change. An atom's nucleus is made up of protons and neutrons. It seems to reason that a nuclear reaction alters the amount of protons and/or neutrons in an atom.

Chemical changes occur when bonds between molecules or atoms are broken and/or formed to form a new material. In this case, the new substances' qualities differ from the old, the particles differ, and the number of particles can alter.

The change in energy for a nuclear change is many orders of magnitude greater than the change in energy for a chemical change.

Answer:

1.0001 M

Explanation:

Molarity = Mass/(Volume x molar mass)

Molarity = 98.0 g/(1.00 L x 97.994 g/mol)

Molarity = 1.0001 M

the molarity of 98.0 g of phosphoric acid, H3PO4 in 1.00 L of solution is 1.0001 M

Molarity can be defined as the number of moles of solute available in a definite concentration and amount of the solution, other wise called as moles per liters of a solution.

Molality of a solution can be defined as the number of moles per solute can be present in a kilogram of the solvent,  which is moles per kilogram of a solvent.

Though the terms Molarity and Molality are quite similar but the sharp difference between them as it creates a huge difference while using this two form of calculation  for various calculations.

Molarity = Mass/(Volume x molar mass)

Here, Molarity = 98.0 g/(1.00 L x 97.994 g/mol)

Molarity = 1.0001 M

I assume that you mix the 25 mL alcohol with 45 mL water.

The answer depends on a big IF : IF the volumes are additive. Very often volumes of liquids are not additive

Total volume = 70 mL

isopropyl alcohol %(v/v) = 25mL/ 70 mL * 100 % = 35.7% v/v

The answer should have only 2 significant digits: 36%v/v

Explanation:

Hope it helps

The percent by volume  of a solution formed by mixing 25 ml of isopropanol with 45 ml of water is 35.71% which is rounded off to 36%.

Percent volume is defined as the concentration of a particular solute which is measured in terms of volume present in a solution. The volume of the solution is present in the denominator which indicates the total volume of all components .

It is expressed as,

percent volume= volume of solute/volume of solution×100

It is used for solutions which are made by mixing two components . It is one of the ways of expressing concentrations of mixture with a dimensionless quantity.

Percent volume of the given solution is calculated by substituting the given values in the formula like, 25/70×100=35.71%

Thus, the percent by volume concentration of the solution is 35.71%≈36%.
