All of the following contribute to the large, negative, free-energy change upon hydrolysis of "high-energy" compounds except: a.

klasskru [66]

Answer:

C) low activation energy of forward reaction

Explanation:

Activation energy for the forward reaction is the quantity of free energy which is needed for a reaction to move from the reactant phase of energy level to the transition state of energy level. The higher the rate of energy level, the slower the chemical reaction.

Activation energy is a barrier that must be overcome for a reaction to take place.

a 150.0 ml sample of an aqueous solution at 25°c contains 20.0 mg of an unknown nonelectrolyte compound. if the solution has an

Nostrana [21]

The molar mass of the unknown compound is 223.2 g/mol.

Solution:

Molarity = $\frac{Weight}{molecularweight} * \frac{1000}{Volume (ml)}$

$4.54*10^{-4} = \frac{0.0152g}{molecularweight} * \frac{1000}{150.ml}$

Molecular weight = 223.2 g/mol

The main difference between the two is that molar mass refers to the mass of one mole of a particular substance. Molecular weight is the mass of a molecule of a particular substance. Although the definitions and units of molar mass and molecular weight are different, the values are the same.

The formula mass of a molecule is the sum of the atomic weights of the atoms in that molecular formula. The molecular weight of a molecule is the average mass calculated by adding the atomic weights of the atoms in the molecular formula. Molecular weight is the mass of a single molecule, specifically the mass of material required to make a single mole.

11.) NaHCO₃ + (CH3COOH CO₂ + H₂O + NaCCH Scoo balance?

Nady [450]

NaHCO3 + CH3COOH = Na(CH3COO) +H2O +CO2.

<h3>Explanation:</h3>

Balancing a chemical equation is very important in case of both laboratory and industrial purpose. It gives us the stoichiometric ratio of the reactants which reacts together and how much product we can expect from the reaction.

Here, sodium bicarbonate reacts with acetic acid or vinegar to produce sodium acetate, carbon dioxide and water. Actually carbonic acid is produced which is decomposed to carbon dioxide and water.

Now balancing the equation, we get,

NaHCO3 + CH3COOH = Na(CH3COO) +H2O +CO2.

So this reaction is already balanced. It means 1 mole of each reactant reacts to produce 1 mole of each product.
