How do you find the molar mass of an unknown?.

Answers

Answer 1

To find the molar mass of an unknown element/compound use the following steps:

Step 1: Using the chemical formula, calculate the number of atoms in each element in the compound.

Step 2: Multiply each element's atomic weight by the number of atoms in the compound.

Step 3: Total everything and assign a unit of measurement of grams/mole.

for eg: What is the molar mass of sodium carbonate (Na2CO3)?

Solution: Sodium carbonate contains two sodium atoms, one carbon atom, and three oxygen atoms. The atomic weight would be

Na : 2 x 23.0 = 46

C : 1 x 12.0 = 12

O : 3 x 16 = 48

When we add the total values, we get 106 (46 + 12 + 48).

As a result, Na2CO3 has a molar mass of 106 g/mole.

Is CH3 nonpolar covalent?.

Answers

Methane creates a covalent bond that is non-polar. This is due to the fact that there is almost any distinction between the electronegativity of carbon and hydrogen.

Because the electronegativities of the C and H are comparable when we simply consider CH₃, we declare it to be non-polar. As a result, they cancel one another, making CH₃ non-polar.

A methyl anion, the [CH₃-] group, has covalent connections between its carbon and hydrogen atoms. Although a C-H bond has no bond polarity, the anion has molecular polarity because of the negative charge attached to carbon.

Which of the following pH values indicates a solution with the highest concentration of hydrogen ions? A. pH = 1, B. pH = 2, C. pH = 7, D. pH = 14.

Answers

A solution with a higher number of free hydrogen ions would have lesser pH than a solution having comparatively lower number of free hydrogen ions. Thus, the answer would be Option A i.e. pH = 1.

On the pH ( denoting potential or power of hydrogen) scale , the number which has the highest concentration of  hydrogen ions must generally be 0. This represents or marks a chemical/solution with a hydrogen ion concentration of 1 mole/liter or a solution of 1 M (Molarity). Such high concentrations/numbers of hydrogen ions are typically only found in solutions/mixtures made with a strong acid when completely dissociates in water (hydrochloric acid is an example of such solution). We generally treat the pH scale from zero(0) to fourteen (14). For each pH unit, the concentration of hydrogen ions or the number of free hydrogen ions decreases by an order of 10. However, for a solution of pH of less than 0 to exist, a higher hydrogen ion concentration than 1 M concentration would be required.

The lowest known pH is -3.6 from  which is achieved by extremely acidic mine water.

Thus, acids generally have high concentrations of hydrogen atoms.

Hence, the answer to the question would be an option with lowest pH score, which is option A.

Explain why your lung capacity and breathing rate are larger when you are exercising than when you are asleep

Answers

When exercising, the body requires more oxygen to fuel the muscles and produce energy. To meet this increased demand for oxygen, the lungs increase their capacity and breathing rate. This allows for more oxygen to be taken in with each breath and for the oxygen to be delivered to the muscles more quickly.

During exercise, the body's metabolism increases as the muscles need more energy to perform the exercises. As a result, the heart rate increases and the blood vessels dilate, allowing for more blood to flow through the body and deliver oxygen to the muscles. The lungs also respond to the increased demand for oxygen by increasing their capacity and breathing rate to take in more oxygen with each breath.

Additionally, the diaphragm and intercostal muscles that control the lungs' expansion and contraction also play an important role in this process. During exercise, these muscles work harder, allowing the lungs to expand more and take in more oxygen with each breath.

On the other hand, when you're asleep, the body's metabolism slows down and the muscles are at rest. So, the body doesn't need as much oxygen as it does during exercise. As a result, the lungs' capacity and breathing rate decrease, allowing for less oxygen to be taken in with each breath and for the oxygen to be delivered to the body more slowly.

In summary, when exercising the body requires more oxygen to fuel the muscles and produce energy, and the lungs increase their capacity and breathing rate to meet this increased demand for oxygen, allowing for more oxygen to be taken in with each breath and for the oxygen to be delivered to the muscles more quickly.

Usually people breathe more gradually while they are sleep, and as sleep stages progress, inhaling becomes more constant and less unpredictable. Nonetheless, studies have shown that when we are in the rapid eye movement (REM) sleep hormone, we also breathe more rapidly and unevenly.

Your lungs and cardiovascular system work quite hard while you exercise. They work together to bring oxygen into the system and get it to the working muscles. This helps your lungs work better by subsequently increases and fortifying the tissue surrounding them.

About Acid rain

Acid rain is defined as all kinds of rain with a pH below 5.6. Rain is naturally acidic (pH slightly below 6) because carbon dioxide (CO2) in the air which dissolves with rainwater has the form a weak acid . This type of acid in rain is very useful because it helps dissolve the minerals in the soil which are needed by plants and animals.

Acid rain is caused by Sulfur which is an impurity in fossil fuels as well as nitrogen in the air which reacts with oxygen to form sulfur dioxide and nitrogen oxides. These substances diffuse into the atmosphere and react with water to form sulfuric acid and nitric acid which are easily soluble so that they fall with the rainwater. This acidic rainwater will increase the acidity of the soil and surface water which will prove harmful to fish and plant life. Efforts to overcome this are currently being intensively implemented.

Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time (for example, 60 km/h northbound). In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined. Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system). In contrast to "5 metres per second east," which is a vector, "5 metres per second," for instance, is a scalar.

By dividing the distance by the time, the ball's speed is determined. The average speed will be 60/3, or 20 feet per second (6.1 metres per second), if the time was 3 seconds.
