¿A qué se refiere cuando se dice que el trabajo científico es cualitativo y cuantitativo? Por favor

Answers

Answer 1

Answer:

ver explicacion

Explanation:

La investigación cualitativa tiene que ver con la investigación que implica la recopilación de datos no numéricos, mientras que la investigación cuantitativa tiene que ver con la recopilación de datos numéricos.

La investigación científica a menudo tiene que ver con la observación y la realización de inferencias. Este aspecto de la investigación científica es cualitativo.

Al mismo tiempo, es posible que también se requieran gráficos, tablas y cuadros para la presentación de datos en ciertos tipos de investigación científica. Esta es ahora una investigación cuantitativa.

Por tanto, la investigación científica es tanto cualitativa como cuantitativa

Which of the following is not a reason why actual yield is less than theoretical yield?

A. presence of impure reactants

B. conservation of mass

C. competing side reactions

D. loss of product during purification

Answers

Your answer is B, conservation of mass


Recall that percent yield is given by: %Yeild = actual yeild/theoretical yeild x100

During experiments, there are errors made:

• uncertainty in measurements

• losses of reactants and products

• impurity in reactants

• losses during separation (e.g. filtration or purification)

• Some side reactions might also happen.



Among the given options, only conservation of mass does not contribute to a lower actual yield compared to the theoretical yield.

The option that isn't a reason why the actual yield is less than theoretical yield is B. conservation of mass.

It should be noted that the formula for the percent yield is given as:

= Actual yield / Theoretical Yield × 100

The actual yield is experimentally determined, and it's the quantity of a product that is gotten from a chemical reaction.

The theoretical yield is the amount of product that can be obtained from a reaction when the reactants are changed to products.

Actual yield can be less than theoretical yield due to the presence of impure reactants ,competing side reactions, and loss of product during purification.

In conclusion, the correct option is B.

(1) The solubility of Salt AB2(S) IS 5mol/dm^3.
a. Obtain an expression for the solubility product of AB2(S),in terms of s.
b. Calculate the Ksp of AB2,given that solubility is 2.4x10^3mol/dm^3

Answers

Answer:

a. Ksp = 4s³

b. 5.53 × 10⁴ mol³/dm⁹

Explanation:

a. Obtain an expression for the solubility product of AB2(S),in terms of s.

AB₂ dissociates to give

AB₂ ⇄ A²⁺ + 2B⁻

Since 1 mole of AB₂ gives 1 mole of A and 2 moles of B, we have the mole ratio as

AB₂ ⇄ A²⁺ + 2B⁻

1 : 1 : 2

Since the solubility of AB₂ is s, then the solubility of A is s and that of B is 2s

So, we have

AB₂ ⇄ A²⁺ + 2B⁻

[s]        [s]    [2s]

So, the solubility product Ksp = [A²⁺][B⁻]²

= (s)(2s)²

= s(4s²)

= 4s³

b. Calculate the Ksp of AB₂, given that solubility is 2.4 × 10³ mol/dm³

Given that the solubility of AB is 2.4 × 10³ mol/dm³ and the solubility product Ksp = [A²⁺][B⁻]² = 4s³ where s = solubility of AB = 2.4 × 10³ mol/dm³

Substituting the value of s into the equation, we have

Ksp = 4s³

= 4(2.4 × 10³ mol/dm³)³

= 4(13.824 × 10³ mol³/dm⁹)

= 55.296 × 10³ mol³/dm⁹

= 5.5296 × 10⁴ mol³/dm⁹

≅ 5.53 × 10⁴ mol³/dm⁹

Ksp = 5.53 × 10⁴ mol³/dm⁹

what are the difference between ionic bond and covalent bond?

Which is stronger?​

Answers

QUËSTIONS :- what are the difference between ionic bond and covalent bond?

IONIC BONDS :- THEY R BONDS WHICH R FORMED DUE TO THE COMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS

COVALENT BONDS :- THEY R THE BONDS WHICH R FORMED DUE TO INCOMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS

IONIC BONDS R MORE STRONGER.

Explanation:

Ionic bond is much stronger than covalent bond because it involves complete transfer of electrons because of which there is formation of cation and anion and there exist huge electrostatic forces of attraction. They also have high melting and boiling point which proves that the ionic bond is very strong.

Differences between ionic bond and covalent bond :

Ionic Bonds. Covalent Bonds

Polarity :High. Low

Shape : No definite shape. Definite shape

Melting Point :High Low

Boiling Point: High Low

how to determine the aspects for core and valence electrons in a periodic table. How comes in some elements like cobalt the 3d is on the valence side and arsenic the 3d is on the core side.​

Answers

Answer:

See explanation

Explanation:

The electron configuration of an atom in an element determines the property of the atom. The core electrons are found inside the atom while the valence electrons are found on the outermost shell of the atom.

For cobalt, the outermost shell electron configuration is; [Ar] 3d7 4s2. The 3d7 and 4s2 are found in the valence shell of cobalt.

For arsenic, the electronic configuration is [Ar] 3d¹⁰ 4s² 4p³. The valence electrons are 4s2, 4p3. The 3d electrons are found inside the arsenic atom.

what is the difference between the chemical bonds formed in molecules of O2 and the chemical bonds formed in the crystal of NaCi

Answers

Explanation:

The bond between two oxygen atoms is covalent (covalent bonding is bonding between Non metals (the electrons are shared)).

The bond between the Na and Cl (NaCl) is ionic (ionic bonding is bonding between a metal (in this case the Na) and a non metal (the Cl). This type of bonds deals with the metal losing electrons and the non metal gaining electrons. The metal therefore become positively charged (so it becomes ionic) and the non metals gain electrons and become negatively charged (also becomes ionic/ forms an ion). The opposite charges attract each other and this is why they bond.

Answer:

A three-carbon chain has a straight line extending from the center carbon.

Explanation:

Isomers are compounds having the same molecular formula but different structural formulas.

Butane and 2-methylpropane are constitutional isomers. Constitutional isomers differ in the way that the constituent atoms are connected to each other.

Butane is a straight chain compound while the compound 2-methylpropane consists of a three-carbon chain which has a straight line extending from the center carbon.
