Explanation:

The freezing point of the solvent in a solution changes as the concentration of the solute in the solution changes (but it does not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution).

Generally, pressures lower than 1 atmosphere lower the temperature at which a substance freezes, but for water, a higher pressure gives a lower freezing point. The force from a pressure change figures into the molecular forces already at play in a substance.

7.54 *\(10^8\) meters is  75.4 nanometers.

To convert 7.54 *  \(10^8\) meters to nanometers, you can multiply the value by \(10^9\)

as,  \(10^9\)nanometers = 1  meter.

7.54 * \(10^8\) m * \(10^9\) =  7.54 x \(10^1\) nm

Therefore, 7.54 *\(10^8\) meters is equal to 75.4 nanometers.

To convert 7.54 x 10^-8 meters to nanometers, you multiply 7.54 x 10^-8 by 1 x 10^9 to get 75.4 nanometers.

To convert meters to nanometers, you need to know that 1 meter is equivalent to 1 x 109 nanometers. Therefore, if you were to convert 7.54 x 10-8 m to nanometers, you would multiply 7.54 x 10-8 by 1 x 109.

Here's how you'd do it: 7.54 x 10-8 m * 1 x 109 nm/m = 75.4 nm. So, 7.54 x 10-8 meters is equivalent to 75.4 nanometers.

Answer:

He did not boil his broth long enough and the flasks were not cleaned prior to the experimenter

In the third equation, the oxygen with atomic weight 16 undergo alpha decay and produce C₆¹³ . The alpha particle emitted is also called helium nuclei. During this decay some gamma radiations also produce as a byproduct.

It is also called as radioactive decay during which an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements.

The atom emit the alpha particles consist of two proton and two neutrons. Which is also called Helium nuclei.

When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic number 2 less than the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

Hence, the oxygen with atomic weight 16 undergo alpha decay and produce C₆¹³  and an alpha particle (He)

There is no reason to run these solutes at the 20 MWCO because they are both much smaller than the MWCO of the membrane.

The MWCO (molecular weight cut off) is the molecular weight of a solute at which it will be retained by a membrane during a process such as ultrafiltration or dialysis. If a solute has a molecular weight higher than the MWCO of a membrane, it will be retained and not pass through the membrane. If the molecular weight of a solute is lower than the MWCO, it will pass through the membrane.

In this case, glucose has a molecular weight of 180 g/mol (6 carbons x 12 g/mol per carbon + 6 oxygens x 16 g/mol per oxygen) and albumin has a molecular weight of approximately 81,942 g/mol (607 amino acids x 135 g/mol per amino acid). Both of these solutes have molecular weights that are much lower than 20,000 g/mol, which is a typical MWCO for ultrafiltration or dialysis membranes.

They would both easily pass through the membrane and be lost during the process. Instead, a membrane with a much lower MWCO would be needed if we wanted to retain these solutes during a process such as ultrafiltration or dialysis.

The pKa values of tert-butanol and phenol are determined by the stability of their respective conjugate bases, which are formed when a proton is removed from each molecule. The higher the stability of the conjugate base, the weaker the acid and the higher the pKa.

In the case of tert-butanol, the conjugate base (tert-butoxide ion) is stabilized by the electron-donating effect of the three alkyl groups attached to the central carbon atom. These alkyl groups increase the electron density on the oxygen atom, making it a better nucleophile and stabilizing the negative charge on the oxygen atom. As a result, the tert-butoxide ion is a relatively stable species, and the pKa of tert-butanol is high (around 16).

In contrast, the conjugate base of phenol (phenoxide ion) is less stable because the negative charge on the oxygen atom is delocalized over the aromatic ring. The pi electrons of the ring can partially stabilize the negative charge, but not to the same extent as the alkyl groups in tert-butanol. As a result, phenol is a stronger acid than tert-butanol, and its pKa is lower (around 10).

Therefore, the difference in pKa between tert-butanol and phenol can be explained by the difference in the electron-donating ability of the substituents attached to the central carbon atom in tert-butanol and the electron-withdrawing effect of the aromatic ring in phenol.

Answer:

Keq = [CO₂]/[O₂]

Explanation:

Step 1: Write the balanced equation for the reaction at equilibrium

C(s) + O₂(g) ⇄ CO₂(g)

Step 2: Write the expression for the equilibrium constant (Keq)

The equilibrium constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species. The equilibrium constant for the given system is:

2 MOLES OF GLUCOSE

Explanation:

How many Moles of glucose are produced from 12 moles of CO2 in photosynthesis?

6CO2 +6H20-------------->C6H12O6 -+ 6O20

(IN THE PRESENCE OF CHLOROPHYLL AND UV FROM )

)

6 MOLES OF CO2 MAKE 1 MOLE OF GLUCOSE

12 MOLES THEN MAKE 2 MOLES OF GLUCOSE

In the photosynthesis process, plants can use 12 moles of carbon dioxide to form 2 moles of glucose.

It is the process by which green plants and some other organisms convert light energy into chemical energy.

Let's consider the balanced equation for the synthesis of glucose through photosynthesis.

6 CO₂ + 6 H₂O ⇒ C₆H₁₂O₆ + 6 O₂

The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1. The moles of glucose formed from 12 moles of carbon dioxide are:

12 mol CO₂  (1 mol C₆H₁₂O₆/6 mol CO₂) = 2 mol C₆H₁₂O₆

In the photosynthesis process, plants can use 12 moles of carbon dioxide to form 2 moles of glucose.

Explanation:

Answer:

Atoms of the same element are exactly alike in all respects and are different from atoms of other elements.

Explanation:

One of the postulates of the Dalton's atomic theory is that 'Atoms of the same element are exactly alike in all respects and are different from atoms of other elements.'

Hence, if carbon dioxide from two sources are obtained and analysed, the mass percentage of carbon in both samples should be exactly the same since they both contain atoms of carbon. The atoms of carbon in the both samples are exactly the same in all respects in accordance with the Dalton's atomic theory, hence the observation.
