Which contains the greatest number of moles of oxygen atoms?
Answer:
B. OR C.
Explanation:
So, 1 mol of ethanol, C2H5OH contains 1 mol of atoms of O; 1 mol of formic acid, HCO2H contains 2 moles of atoms of O; and 1 mol of water, H2O contains 1 mol of atoms of O.
Answer: So, of the three compounds given, formic acid, HCO2H, contains the greatest number of moles of oxygen atoms.
what makes up the cell menbrane
With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.
Explanation:
the principal components of plasma membrane are lipids phospholipid and cholesterol proteins and carbohydrates
Balance the chemical equation below using the smallest possible whole number stoichiometric coefficients.
The balanced chemical equation using the smallest possible whole number stoichiometric coefficients is:
[tex]3Br_{2} + I_{2} \rightarrow 2IBr_{3}[/tex]
What is a balanced equation?A balanced chemical equation is an equation in which the the moles of atoms in of elements of reactants is equal to mole of atoms of elements of the product.
The balanced chemical equation of the reaction is given below:
[tex]3Br_{2} + I_{2} \rightarrow 2IBr_{3}[/tex]
Therefore, the balanced chemical equation using the smallest possible whole number stoichiometric coefficients is given above.

why iodide ions cannot be determined by Mohr method
Answer:
Exactly the same approach can be used for determination of bromides. Other halides and pseudo halides, like I- and SCN-, behave very similarly in the solution, but their precipitate tends to adsorb chromate anions making end point detection difficult.
Hope it helps!
Mohr method is the titration method, used for the determination of the chloride ion concentration in solution. It can not be used for iodine ions, as the alkaline titration is not suitable for iodine.
What is titration?Titration is the analytical process used for the determination of the concentration of a compound, by reacting it with titrant.
The mohr method is the titration method, that determines the concentration of the cations in the solution by titrating them with the salt. The salt formed precipitate in the reaction and the end point is determined.
The limitation to the use of mohr method, is its inability for the analysis of the chlorides of cations, as the reaction is carried out at high pH in alkaline conditions.
The iodide slats are suitably precipitated in the alkaline solution, and thus limits the use of the mohr method.

what is a mole and its properties
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.

Mention the factors affecting the rate of reaction
There are four main factors that can affect the reaction rate of a chemical reaction:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...
Physical state of the reactants and surface area. ...
Temperature. ...
Presence of a catalyst.
ould it make any difference if the methylene chloride solutioncontaining both thebasicand neutral components waswashed with 1Msodium hydroxiderather than 1Mhydrochloric acid? If so,what would that difference be? Would any layer separation bepossible in the new solution? Would it be possible to isolate the two components from oneanother using 1Msodium hydroxiderather than 1Mhydrochloric acid?Why or why not?Provide a balanced equation to justify your answ
Answer:
Explanation:
No, it is ludicrous and not possible to separate and detach a basic and neutral compound by 1M NaOH in DCM. This is due to the fact that neutral compounds don't respond and react with NaOH, and NaOH itself occurs to be a base. As a result, it can't respond and react with another base to produce salt. Consequently, we simply need a corrosive component i.e an acid
So; In DCM, we can't use 1M NaOH instead of 1M HCI for isolation and separation of neutral and basic compound mixtures.
Which law of thermodynamics? Defines what thermal equilibrium is.
2nd
1st
0th
Answer:
0th
Explanation:
he laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium. The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and establish relationships between them. They state empirical facts that form a basis of precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, they are important fundamental laws of physics in general, and are applicable in other natural sciences.
Traditionally, thermodynamics has recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law.[1][2][3] A more fundamental statement was later labelled as the zeroth law, after the first three laws had been established.
