Answer:I think the answer would be 2 mol/L

Answer:

0.087 g/cm^3

Explanation:

Density is Mass : Volume.

Volume = 12 x 8 x 9 = 864 cm^3

Mass = 75 g

Density = 75g/864 cm^3 = 0.087 g/cm^3

The density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

Density is defined as the mass per unit volume of the body. Mathematically-

ρ = M/V

Given is a 75 g block of wood measuring 12 cm x 8 cm x 9 cm.

We can write -

Mass = [m] = 75 g = 75/1000 = 0.075 Kg

Volume = [V] = L x B x H = 12 x 8 x 9 = 864 cm³

Therefore, the density of the object will be -

ρ = M/V

ρ = 0.075/864

ρ = 8.6 x 10⁻⁵ Kg/cm³

Therefore, the density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

Answer:

2 moles NaClO3

Explanation:

2NaClO3 --> 2NaCl + 3O2

moles NaClO3 = 3 moles O2 x (2 moles NaClO3/3 moles O2) = 2 moles

conversion factor: 2 moles NaClO3 = 3 moles O2

In order to produce 3 moles of [tex]O_{2}[/tex], the chemical reaction needs to be balanced. the required number of moles of [tex]NaClO_{3}[/tex] are 2.

When the reactants undergo a chemical reaction, the number of moles on both the reactant and the product side must be balanced.

The chemical reaction of [tex]NaClO_{3}[/tex] is

2 [tex]NaClO_{3}[/tex]⇄2NaCl  + 3 [tex]O_{2}[/tex]

On the left side, 2 moles of [tex]NaClO_{3}[/tex] breaks into 2 moles of NaCL and 3 moles of [tex]O_{2}[/tex]. on the right side. Therefore, both side have an equal number of moles of each element.

Hence, two moles of [tex]NaClO_{3}[/tex] is required to produce 3 moles of [tex]O_{2}[/tex].

Answer:

D is the most soluble in water at 60 degrees Celsius

According to the data given in the table, the salt is most soluble at 60o C - salt D.

In the given table it is given that all the salts are soluble in different concentrations in different concentrations of the water at the same temperature of 60 degrees celsius.

Converting them in the same amount of H₂O that is 100 grams in the same ratio:

Thus, the salt D is the most soluble that is 50 grams per 100 gram H₂O.

Answer:

La Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC) en su Artículo 1, lo define como ‘un cambio de clima atribuido directa o indirectamente a la actividad humana que altera la composición de la atmósfera mundial y que se suma a la variabilidad natural del clima observada durante períodos de tiempo comparables’. La CMNUCC distingue entre ‘cambio climático’ atribuido a actividades humanas que alteran la composición atmosférica y ‘variabilidad climática’ atribuida a causas naturales.

Los científicos han encontrado evidencias de que el clima en el planeta está cambiando a un ritmo más acelerado de lo esperado y que nuestras actividades ligadas a la producción, extracción, asentamiento y consumo, son la principal causa de este aceleramiento en el cambio.

El mayor problema de un cambio acelerado en el clima es que nuestras sociedades no están preparadas para asumir los cambios que esto nos pueda traer: derretimiento de las masas glaciares y nevados que abastecen acueductos, cambios en los ciclos de floración y fructificación de las plantas de cultivo, ascensos en el nivel de los mares donde hay mucha población viviendo, mayor ocurrencia y fuerza en lluvias, sequías, huracanes, heladas y granizadas en áreas urbanas y rurales, entre otros fenómenos que sin duda reducen nuestra calidad de vida.

The person who looks at the different area managers in a large corporation such as in HR, Business Information and Operations is known as a general manager.

An organizational structure can be described as the process which involves dividing an organization into several functional units. A functional organizational structure is a kind of structure used to organize staff by categorizing them into several departments based on their roles or functions, skill sets, and knowledge.

These departments are vertically structured and may include IT, sales, finance and marketing, research, customer service, etc. The various departments are headed by functional managers who have the responsibility of managing, overseeing, and reporting to the executive management.

A manager is an individual who has the responsibility of providing guidance,  supervision, support, and administrative control, as well as acting as a role model to the employees working in an organization.
