What volume of benzaldehyde (ml) is 3 .00 mmol? the density of benzaldehyde is 1.045 g/ml.

Answers

Answer 1

The volume of benzaldehyde (ml) is 304.65 mL, if the density of benzaldehyde is 1.045 g/ml and having 3 mol.

Given,

Moles of benzaldehyde = 3 mol

Density of benzaldehyde = 1.045g/mol

Molar mass of benzaldehyde = 106.12 g/mol.

As we know that,

Moles can be calculated as

Moles = Given mass/ molar mass

3 = Given mass/ 106.12

Given mass = 318.36g.

The mass of benzaldehyde is 318.36g.

Now,

Density = mass/ Volume

1.045 = 318.16/ Volume

Volume = 318.36/1.045

Volume = 304.65 mL.

Thus, we find that the volume of benzaldehyde is

304.65 mL.

Answers

Sometimes adding heating of substance set of answer options does not cause a change in temperature. resulting in an increase in temperature every time. results occasionally in a drop in temperature.

A substance's atoms and molecules move more quickly when it is heated. Whether the substance is a solid, liquid, or gas, this occurs. However, the temperature does not always rise when more heating of substance is added. For instance, adding heat to boiling water will not raise its temperature. This occurs when the heating of the substance reaches its boiling point, which is for all vaporizable substances. The average kinetic energy of the molecules will fluctuate when a system gains or loses heat. So long as a phase shift is not taking place, heat transfer causes a change in the system's temperature.

The solid BaO and MgO in the flask completely reacted to form BaCO₃(s) and MgCO₃(s), respectively. After the reactions to form BaCO₃(s) and MgCO₃(s) were completed, the pressure of CO₂(g) remaining was 115 torr, still at 30.0°C. Calculate the mass of BaO(s) in the initial mixture in grams. (Assume ideal gas behavior).

Answers

By the use of stoichiometry, the mass of BaO in mixture is 0.06475 g.

What is the mass of BaO?

From the question;

V = 3.50 LT = 303 K P = 750 torr

Mass of BaO in the mixture = x grams

Mass of MgO in the mixture = (6.35 - x) grams

Number of  moles of CO2 initially present;

PV = nRT

= ((750/760) × 3.50) / 0.0821 × 303

n= 0.139

Number of moles of CO2 at the end;

n= PV /RT

= ((245/760) × 3.5) / 303 × 0.0821

= 0.045 mole

Amount of CO2 reacted;

= 0.139 - 0.045

= 0.044 mole

Now;

amount of reacted CO2 = ( amount of BaO + amount of MgO)

amount of BaO in mixture = x / 153 mole

amount of MgO in mixture = 6.35 - x mole / 40

Hence;

= x/ 153 + 6.35/40 = 0.094

= x/153 + 6.35 / 40 - x/40 = 0.094

= x (1/40 - 1153) = (6.35/40 - 0.094)

= x × 10.018464

= 0.06475 g

Hence, the mass of BaO in mixture is 0.06475 g.

Calculate the molality of a sulfuric acid solution containing 24. 4 g of sulfuric acid in 198 g of water

Answers

Answer:

1.26 m

Explanation:

The molality equation looks like this:

Molality = moles solute / mass solvent (kg)

In this case, sulfuric acid is the solute and water is the solvent. To calculate the molality, you need to (1) convert grams solute to moles solute (via molar mass), then (2) convert grams solvent to kilograms solvent, and then (3) calculate the molality.

(Step 1)

Molar Mass (H₂SO₄): 2(1.008 g/mol) + 32.065 g/mol + 4(15.998 g/mol)

Molar Mass (H₂SO₄): 98.073 g/mol

24.4 grams H₂SO₄                1 mole
-----------------------------  x  ------------------------  =  0.249 moles H₂SO₄

Answers

The results of photosynthesis are used by cellular respiration, and photosynthesis first uses the results of cellular respiration.

Enthalpy of photosynthesis and cellular respiration:

In the mitochondria, cellular respiration combines oxygen and glucose to produce ATP, along with water and carbon dioxide. Sunlight energy is used during photosynthesis to create glucose and separate oxygen from carbon dioxide and water. Globally, the exchange of carbon dioxide and oxygen during photosynthesis or cellular respiration serves to maintain stable levels of oxygen and carbon dioxide in the atmosphere.

Cellular Respiration: [tex]C_6H_1_2O_6+ 6O_2[/tex] → [tex]6CO_2 + 6H_2O[/tex]

Because CO₂ and H₂O are less energetic than the reactants, most notably glucose, the reaction is exothermic and has a negative enthalpy (ΔH < 0). This also makes sense because breathing causes glucose to be converted to energy.

Photosynthesis: [tex]6CO_2 + 6H_2O[/tex]→ [tex]C_6H_1_2O_6+ 6O_2[/tex]

List 4 major types of inhibition modes and clearly indicate the effect on vmax and km for each mode?

Answers

The 4 major types of inhibition are  Competitive Inhibition, Non-competitive Reversible Inhibition,  Non-competitive Irreversible Inhibition, and  Uncompetitive Inhibition.

Types of inhibition modes:

1. Competitive Inhibition: Competing inhibitors are substances that resemble an enzyme's natural substrate so closely that they vie for the active site. In order to stop additional reactions, the inhibitor binds to the active site and stays there.

The inhibitor and substrate fight for the enzyme's active site because the enzyme may react with the inhibitor and release the products as it normally would with its substrate

2. Non-competitive Inhibition:

Reversible: There is no competition in this instance because the inhibitor and substrate are not related. The substrate and the inhibitor may mix at various places of the complexes of the enzymes [E-I], [E-S], and [E-I-S].

And in the Michaelis equation, this kind of inhibition lowers V max but has no impact on Km.The rate at which the enzyme is fully saturated is given by V = V max [S] / Km + [S] (V max).

(Km): The substrate is the Michaelis constant, at which the reaction rate is halved, or at V maximum.

Irreversible: These kinds of inhibitors impact the chemical alteration of an amino acid residue in the enzyme that plays a function in catalysis when they join with the enzyme nearby or at the active site.

       Additionally, this kind of inhibition lowers Vmax but has no impact on Km.

3. Uncompetitive Inhibition: is the last type, where the inhibitor attaches to the [E-S] complex to create [E-S-I] even if it has no affinity for the enzyme.

However, this kind of inhibition lowers both Vmax and Km.

Because it might result in eye discomfort or tissue damage if it is not maintained, isotonicity is regarded as a crucial component of ophthalmic medicines. A few drops of blood are mixed with the test preparation before being examined and judged under a microscope at a magnification of 40. Isotonic solutions are those that have the same amount of water and other solutes in them as the cytoplasm of a cell. Since there is no net gain or loss of water, placing cells in an isotonic solution will not cause them to either shrink or swell.

We can calculate the osmotic pressure exerted by a solution using the following expression.

π = M . R . T

where,

π is the osmotic pressure

M is the molar concentration of the solution

R is the ideal gas constant

T is the absolute temperature

The absolute temperature is 37 + 273 = 310 K

π = M . R . T

8 = (X mol/L) . (0.082atm.L/mol.K) . 310 K = 0.3147 mol/L
