Answer:

A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.

Explanation:

A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.

The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.

As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.

The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.

Thus the function of bladder and water balloon are found to be same.

The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000

Explanation:

there is 140 grams in 3.5 atoms of carbon

Answer:

if 12 moles are produced then it came 24 moles of Al(OH)3

Explanation:

The number that is written in front of the molecule is called stoichiometry, represents the number of mole of that molecule. 12 moles of [tex]Al_{2}O__{3}[/tex] is produced by 24 mole of Aluminum.

Stoichiometry is a part of chemistry that help us in making relationship between reactant and product from quantitative aspects. It tells about how much part of reactant will be required to produce particular product. Unitary method is always applied in case of stoichiometry chemistry.

The balanced equation is

[tex]4Al+3O_{2}\rightarrow 2Al_{2}O__{3}[/tex]

The mole ratio between  [tex]Al_{2}O__{3}[/tex] and Al is 2:4, means to produce 4 moles of [tex]Al_{2}O__{3}[/tex] we need 2 moles of Aluminum

4 mole of [tex]Al_{2}O__{3}[/tex]= 2 moles of Aluminum

1 mole of [tex]Al_{2}O__{3}[/tex]=(1÷2) moles of Aluminum

12 moles of [tex]Al_{2}O__{3}[/tex]= 24 mole of Aluminum

Therefore 12 moles of [tex]Al_{2}O__{3}[/tex] is produced by 24 mole of Aluminum.

Explanation:

Answer:

48 grams

Explanation:

The chemical equation for the reaction is the following:

2 H₂ + O₂ → 2 H₂O

That means that 2 moles of H₂ react with 1 mol of O₂ to produce 2 moles of H₂O. We convert the moles of oxygen (O₂) by using the molecular weight (MW) as follows:

MW(O₂) = 16 g/mol x 2 = 32 g/mol

mass of O₂ = 1 mol x 32 g/mol = 32 g

So, we have the following stoichiometric ratio: 32 g O₂/2 moles H₂. We have 3 moles of hydrogen (H₂), so we multiply the moles by the stoichiometric ratio to calculate how many grams are needed:

3 moles H₂ x 32 g O₂/2 moles H₂ = 48 g O₂

Therefore, 48 grams of O₂ are needed to react with 3 moles of H₂.

Answer:

M = 0.47

Explanation:

1 - Turn grams to moles using molar mass:

16g NaOH × 1 mol NaOH / 40g NaOH = 0.4 mol NaOH

2- Turn milliliters to liters:

855mL × 1 L / 1000mL = 0.86 L

3- Use formula which is M = moles of solute / liters of solvent:

M = 0.4 mol NaOH / 0.86 L = 0.47

Answer:

The volume will be 568.89 mL.

Explanation:

Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

or P * V = k

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. That is, the pressure of the gas is directly proportional to its temperature. Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T}=k[/tex]

Where P = pressure, T = temperature, K = Constant

Finally, Charles's law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T}=k[/tex]

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

[tex]\frac{P*V}{T} =k[/tex]

Studying an initial state 1 and a final state 2, it is fulfilled:

[tex]\frac{P1*V1}{T1} =\frac{P2*V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{960 mmHg*550 mL}{473K} =\frac{830 mmHg*V2}{423 K}[/tex]

Solving:

[tex]V2=\frac{423 K}{830 mmHg} *\frac{960 mmHg*550 mL}{473K}[/tex]

V2= 568.9 mL

The volume will be 568.89 mL.

Answer:

2.040 mol CO

Explanation:

First, write out your reaction:

CO + O2 --> CO2

Balance the reaction:

2CO + O2 --> 2CO2

Now divide the 32.65 g O2 by the molar mass of O2 (32.00 g/mol) to get moles of O2. Then multiply by the mole ratio of 2 mol CO for every 1 mol O2 to get moles of CO needed to fully react.

32.65 g O2 / 32.00 g/mol = 1.020 mol O2

1.020 mol O2 • 2 mol CO / 1 mol O2 = 2.040 mol CO
