El ejercicio completo con las formulas es el siguiente:

cuál de las siguientes fórmulas no cumple con la tetravalencia del átomo de carbono.

a. CH3-CH2-CH2-OH

b. CH3-CH=CH2

c. CH3-CH2=CH2

d. CH3-CH2-CH3

Answer:

La respuesta correcta es la opción C

Explanation:

En la formula C, podemos ver claramente que no se cumple con la tetravalencia del carbono pues al sumar el total de las valencias del carbono nos da 5

CH3 - CH2  =   CH2 = Total de valencias del carbono 5

         1 + 2+  2   =  5

Para que la formula sea correcta debe eliminarse un hidrogeno quedando la formula de la siguiente manera:

                      CH3   -  CH   =   CH2

                                 1 +  1  + 2 =  4

Determine the pH of a KOH solution made by mixing 0.251 g KOH with enough water to make 1.0 × 10 2 mL of solution
vesna_86 [32]

Answer:

pH = 12.65

Explanation:

From the given information:

number of moles =mass in gram / molar mass

number of moles of KOH = mass of KOH / molar mass of KOH

number of moles of KOH =  0.251 g / 56.1 g/mol = 0.004474 mol

For solution :

number of moles = Concentration × volume

concetration = number of moles/ volume

concetration = 0.004474 mol / 0.100 L

concetration  = 0.04474 M

We know that 1 moles KOH result into 1 mole OH⁻ ions

Therefore,  Molarity  of OH⁻ = 0.04474 M

Now,

pOH = -log[OH⁻]

pOH = -log (0.04474) M

pOH = 1.35

Similarly,

pH + pOH = 14

pH = 14 - pOH

pH = 14 - 1.35

pH = 12.65

Which of these solid compounds are most likely to have its dominant bonding mechanism as covalent? (Select all that are true.)
I am Lyosha [343]

The compounds that have covalent bonding as their dominant bonding scheme are diamond and silica.

A covalent bond is formed between two nonmetals. Usually, when two nonmetals combine, electrons are shared between the two atoms involved in the bond.

Now, the solids diamond and silica are predominantly covalent solids. The atoms that combine in diamond are carbon atoms(nonmetals) while the atoms that combine in silica are silicon and oxygen (nonmetals also)

Hence, diamond and silica both have covalent bonding as their dominant bonding scheme.

Before Darwin published his ideas,all thoughts and theories on design of species came from which book?
ira [324]

Answer:

Darwin had arrived at a complete theory of evolution by 1839, but it was to be another 20 years before he published his ideas of evolution through natural selection in his epochal book On the Origin of Species by Means of Natural Selection.
