Answer:

An isomer is a molecule with the same molecular formula as another molecule, but with a different structure. Isomers contain the same number of atoms of each element, but have different arrangements of their atoms. Isomers do not necessarily share similar properties, unless they also have the same functional groups.

Carbon dioxide in your blood usually causes no problems. But if you have too much or too little of it, you may have a disease or a health emergency.

Carbon dioxide (CO2) is an odourless, colourless gas.

A high concentration can displace oxygen in the air. If less oxygen is available to breathe, symptoms such as rapid breathing, rapid heart rate, clumsiness, emotional upsets and fatigue can result.

As less oxygen becomes available, nausea and vomiting, collapse, convulsions, coma and death can occur.

Answer/Explanation:

The boy's muscle energy changes into potential energy due to the height. it then converts into kinetic energy as it goes further upwards into the air.

Answer:

A

Explanation:

because rate of diffusion is inversely proportional to molecular mass

The combination of high molecular mass and low temperature gives the slowest rate of diffusion.The correct option is c.

When it comes to diffusion, the rate at which a gas spreads out depends on its molecular mass and temperature.

Molecular mass refers to the weight of the gas molecules. The larger the molecules, the slower they move and the slower they diffuse. Therefore, gases with higher molecular mass diffuse more slowly than those with lower molecular mass.

Temperature also affects the rate of diffusion. At higher temperatures, gas molecules have more energy and move faster, resulting in a faster diffusion rate. On the other hand, at lower temperatures, gas molecules have less energy and move slower, leading to a slower diffusion rate.

So, when we combine high molecular mass and low temperature, we have both factors working against a fast diffusion rate. The gas molecules are heavy, which slows down their movement, and the low temperature reduces their energy and speed. As a result, this combination gives us the slowest rate of diffusion.

In summary, the combination of high molecular mass and low temperature gives the slowest rate of diffusion.The correct option is C.

Answer:

9.6 mol

Explanation:

Start by writing out the balanced equation of the reaction.

2[tex]H_{2}[/tex] + [tex]O_{2}[/tex] ⇒ 2[tex]H_{2}O[/tex]

Here you will see 2 mol of hydrogen for every 1 mol of oxygen. Using this ratio, you can assume the amount of hydrogen will always be double that of oxygen. In this case, 4.8 * 2 = 9.6

The standard reaction enthalpy and the standard reaction enthalpy at 400 K for this reaction are equal to 0.35 kJ and 0.000125 kJ respectively.

Mathematically, the Gibbs's free energy for this chemical reaction can be calculated by using this formula:

ΔG° = -RTlnK = ΔH° - TΔS°    ......equation 1.

First of all, we would determine the value of lnK from the given expression at 390 K and 410 K respectively:

lnK = A + B/T + C/T²

lnK = -1.04 - 1088/T + 1.51 × 10⁵/T²    

lnK = -1.04 - 1088/390 + 1.51 × 10⁵/390²

lnK = -1.04 - 2.79 + 0.99

lnK = -2.84.

At T = 410 K, we have:    

lnK' = -1.04 - 1088/410 + 1.51 × 10⁵/410²

lnK' = -1.04 - 2.65 + 0.90

lnK' = -2.79.

For the standard reaction enthalpy, we have:

lnK' - lnK = ΔH°/R(1/T - 1/T')

-2.79 - (-2.84) = ΔH°/8.314(1/390 - 1/410)

-2.79 + 2.84 = ΔH°/8.314(0.00256 - 0.00244)

0.05 = ΔH°/8.314(0.0012)

0.4157 = 0.0012ΔH°

ΔH° = 0.4157/0.0012

ΔH° = 346.42 ≈ 0.35 kJ.

Next, we would determine the Gibbs's free energy at each temperature:

At T = 390 K, we have:

ΔG° = -RTlnK

Δ₁G° = -8.314 × 390 × (-2.84)

Δ₁G° = 9.21 kJ/mol.

At T = 410 K, we have:

Δ₂G° = -8.314 × 410 × 2.79

Δ₂G° = 9.51 kJ/mol.

For the standard reaction enthalpy at 400 K, we have:

ΔG° = ΔH° - TΔS°

9.51 - 9.21 = 0.35 - 400ΔS°

0.30 = 0.35 - 400ΔS°

400ΔS° = 0.35 - 0.30

400ΔS° = 0.05

ΔS° = 0.05/400

ΔS° = 0.000125 kJ.

The specific heat of the metal object with a mass of 22.7g heated to to temperature of 97.0°C and then transferred to an insulated container containing 84.7 g of water at 20.5 ∘C is 0.815J/g°C

How to calculate specific heat?

The specific heat capacity of a metal can be calculated using the calorimetry equation as follows:

Q = mc∆T

Where;

Q = quantity of heat absorbed

m = mass of substance

c = specific heat capacity

∆T = change in temperature

mc∆T (water) = -mc∆T (metal)

84.7 × 4.18 × 3.8 = - (22.7 × c × -72.7)

1345.375 = 1650.29c

c = 0.815J/g°C

Therefore, the specific heat of the metal object with a mass of 22.7g heated to to temperature of 97.0°C and then transferred to an insulated container containing 84.7 g of water at 20.5 ∘C is 0.815J/g°C.

Π = 21.9 atm

Explanation:

The equation used to find osmotic pressure is:

Π = iMRT

In this formula,

   >> Π = osmotic pressure (atm)

   >> i = van't Hoff factor

   >> M = molarity (M)

   >> R = constant (0.0821 atm*L/mol*K)

   >> T = temperature (K)

Remember, van't Hoff factor is the amount of ions the species (MgCl₂) dissociates into while in solution. MgCl₂ dissociates into 3 ions. These ions are Mg²⁺ and 2 Cl⁻.

The temperature needs to be in Kelvin....

37.0 °C + 273.15 = 310.15 K

You now know the value of all the variables.

Π = iMRT

Π = (3)(0.287 M)(0.0821 atm*L/mol*K)(310.15 K)

Π = 21.9 atm

The phenomenon known as "salting-out" occurs at very high ionic strengths, when protein solubility declines as ionic strength rises. As a result, salting out may be used to segregate proteins according to how soluble they are in salt solutions.

Because large levels of sodium chloride disturb the bonds and structure of the active site, the rate of enzyme activity will gradually decrease as the concentration of sodium chloride rises. As a result, some of the active sites get denaturized and the starch loses its ability to attach to them. As more enzymes get denatured and eventually cease to function, enzyme activity will steadily wane.

The percent of water in the hydrated salt will be 55.08 %

Mass is a numerical measure of quantity, which is a basic feature of all matter. The kilogram is the international system of units of mass.

Given data;

Mass of crucible, cover, and contents before heating = 23.4 g.

Mass of empty crucible and cover = 18.82 g.

Mass of crucible, cover, and contents after heating to constant mass = 20.94 g.

⇒Mass of hydrated salt used =  Mass of the crucible, cover, and contents before heating - Mass of the empty crucible and cover                    

⇒Mass of hydrated salt used =   = 23.54 g – 18.82 g

⇒Mass of hydrated salt used =  = 4.72 g

⇒Mass of dehydrated salt after heating = Mass of the crucible, cover, and contents after heating to constant mass-Mass of the empty crucible and cover

⇒Mass of dehydrated salt after heating = 20.94 g – 18.82 g

⇒Mass of dehydrated salt after heating = 2.12 g

⇒ Mass of water liberated from salt = Mass of hydrated salt used -   Mass of dehydrated salt after heating

⇒  Mass of water liberated from salt = 4.72 g – 2.12 g    

⇒  Mass of water liberated from salt = 2.60 g  

Water % in the hydrated salt is found as;

% water =(mass of water/  mass of hydrated salt)× 100

% water =(2.60/4.72) × 100

% water =55.08 %

Hence the percent of water in the hydrated salt will be 55.08 %

          A separation technique called filtration is used to isolate pure chemicals from mixtures of particles, some of which are big enough to be caught by a porous medium.

         The separation of combinations of two or more pure liquids is accomplished through distillation. The components of a liquid mixture are vaporized, then condensed and isolated during the purifying process of distillation.

          Chromatography is the process of separating a mixture by passing it through a medium where the components move at various speeds, either in solution, suspension, or as a vapor (as in gas chromatography).

         The magnetic separation process involves attracting magnetic materials using a magnet to separate the components of mixes. Non-magnetic compounds are separated from magnetic ones using the magnetic separation technique.

Answer:

Explanation:

Ionic compounds are formed between atoms with very different electronegativity (EN) values. The elements with the highest EN values are on the top-right of the periodic table.

Ionic compounds are also generally between a metal and nonmetal. Nonmetals are located in the p-block (the right) of the periodic table and metals are pretty much everywhere else.

That being said, water (H₂O), CO, and CO₂ contain elements that have too similar of EN values to ionically bond.

However, the elements in KCl have different enough EN values to undergo ionic bonding by donating/receiving electrons from each other.
