Using C2H4 + 3 O2 -> 2 CO2 + 2 H2O. If 20 moles of fuel are combusted in the above equation, how many moles of O2 are consumed?

Explanation:

According to the balanced chemical equation:

1 mole of C2H4 reacts with 3 moles of O2

Therefore, for 20 moles of C2H4 combusted, we would need:

20 moles C2H4 × (3 moles O2 / 1 mole C2H4) = 60 moles O2

So, 60 moles of O2 are consumed in the combustion of 20 moles of C2H4.

Answer:

There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process.

Answer :

arginine is basic amino acid because it's side chain group contains a full positive charge at the physiological pH. Histidine is also considered basic but it can have a positive or a neutral charge on its side chain group at the physiological pH

Ammonia (\(NH_3\)) and ammonium chloride (\(NH_4Cl\)) mixture could be a useful buffer in a solution. Option C

A buffer is a solution that can resist changes in pH when small amounts of acid or base are added. It consists of a weak acid and its conjugate base or a weak base and its conjugate acid. The buffer system works by the principle of Le Chatelier's principle, where the equilibrium is shifted to counteract the changes caused by the addition of an acid or a base.

In option A, acetic acid (\(CH_3CO_2H\)) is a weak acid, but hydrochloric acid (HCl) is a strong acid. This combination does not form a buffer because HCl is completely dissociated in water and cannot provide a significant concentration of its conjugate base.

Option B consists of sodium hydroxide (NaOH), which is a strong base, and elemental sodium (Na), which is a metal. This combination does not form a buffer as there is no weak acid-base pair involved.

Option D contains acetic acid (\(CH_3CO_2H\)), a weak acid, and ammonia (\(NH_3\)), a weak base. Although they are weak acid and base, they do not form a buffer system together as they are both weak acids or bases and lack the required conjugate acid-base pair.

Option C, ammonia (\(NH_3\)), is a weak base, and ammonium chloride (\(NH_4Cl\)) is its conjugate acid. This combination can form a buffer system. When ammonia reacts with water, it forms ammonium ions (NH4+) and hydroxide ions (OH-).

The ammonium ions act as the weak acid, while the ammonia acts as the weak base. The addition of a small amount of acid will be counteracted by the ammonium ions, and the addition of a small amount of base will be counteracted by the ammonia, thus maintaining the pH of the solution relatively stable.

Therefore, option C, consisting of ammonia (\(NH_3\)) and ammonium chloride (\(NH_4Cl\)), is the suitable mixture that could be a useful buffer in a solution.

If a strong base is added to a buffer the pH will change only slightly. In the non-buffered solution changing the pH significantly.

If a strong base is added to a buffer, the weak acid will give up its H+ in order to transform the base (OH-) into water (H2O) and the conjugate base: HA + OH- → A- + H2O. Since the added OH- is consumed by this reaction, the pH will change only slightly.

In the non-buffered solution, the added hydronium or hydroxide ions have nothing to react with so the concentrations increase rapidly, changing the pH significantly.  If a base is added to an acidic solution, the solution becomes less acidic and moves toward the middle of the pH scale.

Approximately 194.0 grams of glucose (C6H12O6) would be required to prepare a 5000 mL solution with a concentration of 0.215 M.

To determine the mass of glucose (C6H12O6) required to prepare a 0.215 M solution in 5000 mL, we need to use the formula:

Molarity (M) = moles of solute / volume of solution (in liters)

First, let's convert the volume of the solution from milliliters (mL) to liters (L):

5000 mL = 5000/1000 = 5 L

Now, we can rearrange the formula to solve for moles of solute:

moles of solute = Molarity (M) x volume of solution (L)

moles of solute = 0.215 M x 5 Lmoles of solute = 1.075 mol

Since glucose (C6H12O6) has a molar mass of approximately 180.16 g/mol, we can calculate the mass of glucose using the equation:

mass of solute = moles of solute x molar mass of solute

mass of glucose = 1.075 mol x 180.16 g/mol

mass of glucose = 194.0 g (rounded to three significant figures)

Therefore, approximately 194.0 grams of glucose (C6H12O6) would be required to prepare a 5000 mL solution with a concentration of 0.215 M. It's important to note that the molar mass of glucose used in this calculation may vary slightly depending on the level of precision required.

Answer:

Argon

Explanation:

The element that would most likely be a good substitute for neon is "argon".

These two elements belong to the noble gases in Group 18(8A) of the Periodic Table. They are inert gases - they do not react chemically with other substances.

Argon, as an inert gas is often used whenever an inert atmosphere is needed. Argon is used in incandescent light bulbs. It is used to stop oxygen from corroding the filament. It is also used by welders to protect weld area.

Argon is a good substitute for neon in this context because they possess some physical properties which are similar.

Answer: the anwser is a. cuz i did it so im smart and u should listen to me

Explanation:non>

Answer: In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. The oxygen and nitrogen molecules in air at normal room temperature are moving rapidly at between 300 to 400 metres per second. Unlike collisions between macroscopic objects, collisions between particles are perfectly elastic with no loss of kinetic energy.

Explanation:  This is very different to most other collisions where some kinetic energy is transformed into other forms such as heat and sound. It is the perfectly elastic nature of the collisions that enables the gas particles to continue rebounding after each collision with no loss of speed. Particles are still subject to gravity and hit the bottom of a container with greater force than the top, and giving gases weight. Hope this helps with your problem! Byeeee :DDD

Answer:

D. 132.17 amu

Explanation:

The formula mass of a compound can be determined from the formula of the compound thus, from the number each elements present. The formula mass of (NH₄)₂SO₄ is 132.17 amu.

What is formula mass?

Formula mass of a compound is the mass calculated from its formula. Each elements has a definite mass called its atomic mass expressed in g/mol or amu.

Mass number of an element is the sum of number of its protons and neutrons. The actual mass of an element is calculated with respect to the mass of 1/12th of Carbon-12 and it is called relative mass.

Here, the atomic mass of N = 14.006 amu

                        mass of H = 1.008 amu.

There are 4 hydrogen thus 4 × 1.008 = 4.008 u.

The mass of two units of  NH₄ is = (14.006 + 4.008) × 2

                                                      = 36.028 u.

Atomic mass of sulfur = 32.6 amu

atomic mass of oxygen = 15.9 amu.

Thus for 4 oxygens = 15.9 × 4 =  63.6 u

The mass of SO₄ unit = 32.06 + 67.6 = 96.2u

Thus the total mass of (NH₄)₂SO₄ = 96.2 + 36.028

                                                        = 132.17 amu

Hence, the formula mass of (NH₄)₂SO₄ is 132.17 amu. Thus, option D is correct.

Explanation:

Answer:

The way to make a supersaturated solution is to add heat, but just a little heat won't do the job. You have to heat the water close to the boiling point. When the water gets this hot, the water molecules have more freedom to move around, and there is more space for solute molecules between them.

There are approximately 0.16 moles of gas present in the lungs.

To solve this problem, we can use the ideal gas law, which relates the pressure (P), volume (V), number of moles (n), and temperature (T) of a gas:

PV = nRT

where R is the gas constant.

First, we need to convert the temperature to Kelvin:

T = 37°C + 273.15 = 310.15 K

Next, we can plug in the given values:

P = 1.0 atm

V = 4.0 L

T = 310.15 K

We also need to find the value of R, which depends on the units we are using for pressure, volume, and temperature. In this case, we are using atmospheres, liters, and Kelvin, so we can use the value:

R = 0.08206 L·atm/K·mol

Now we can rearrange the ideal gas law to solve for the number of moles:

n = PV/RT

n = (1.0 atm)(4.0 L)/(0.08206 L·atm/K·mol)(310.15 K)

n = 0.1638 mol

Therefore, there are approximately 0.16 moles of gas present in the lungs.

The sample of nitrogen gas will occupy 236.54 mL of volume at 1.05 atm pressure.

Boyle's law is the ideal law that defines the relationship between pressure and volume of gases. A law is given if the temperature is kept constant. Pressure and volume exhibit an inverse relationship.

The Boyle's Law is given as:

P₁V₁ = P₂V₂

Given,

Initial pressure (P₁) = 0.974 atm

Initial volume (V₁) = 255 mL

Final pressure (P₂) = 1.05 atm

Final volume = V₂

The final volume at 1.05 atm is calculated by substituting values in Boyle's Law as:

P₁V₁ = P₂V₂

0.974 × 255 = 1.05 V₂

V₂ =  248.37 ÷ 1.05
