How might creativity help a scientist?

2 answers:

6 0

Students in science classes usually get the idea that scientific investigations involve careful observation and analysis of data to test hypotheses. One thing that remains shrouded in mystery, however, is how scientists decide on the particular questions they ask in the first place. For example, if you were to ask college biology students what they want to research or what motivates them to study science, they might say, "I want to find a cure for cancer." But if you were to ask which experiments or observations they plan to start with, most students would be at a loss. In contrast, if you were to flip through the table of contents of the journal, Cancer Research, you would find titles like "Ligand-Independent Androgen Receptor Variants Derived from Splicing of Cryptic Exons Signify Hormone-Refractory Prostate Cancer" (Hu et al., 2009). Clearly, the actual research topics scientists choose to study and publish papers about are quite a bit more specific than curing cancer.

A chemist must dilute 34.3mL of 1.72mM aqueous calcium sulfate solution until the concentration falls to 1.00mM. He'll do this b

EastWind [94]

Answer:

58.9mL

Explanation:

Given parameters:

Initial volume = 34.3mL = 0.0343dm³

Initial concentration = 1.72mM = 1.72 x 10⁻³moldm⁻³

Final concentration = 1.00mM = 1 x 10⁻³ moldm⁻³

Unknown:

Final volume =?

Solution:

Often times, the concentration of a standard solution may have to be diluted to a lower one by adding distilled water. To find the find the final volume, we must recognize that the number of moles of the substance in initial and final solutions are the same.

Therefore;

C₁V₁ = C₂V₂

where C and V are concentration and 1 and 2 are initial and final states.

now input the variables;

1.72 x 10⁻³ x 0.0343 = 1 x 10⁻³ x V₂

V₂ = 0.0589dm³ = 58.9mL

Which ocean zone has the lowest water pressure?

Veseljchak [2.6K]

I think the correct answer would be the last option. The ocean zone which has the lowest water pressure would be the uppermost zone which is the Epipelagic zone. This zone is also called as the euphotic zone or the sunlit zone. It is the region which receives the most sunlight in order to allow photosynthesis.

Realiza los cálculos para determinar la cantidad de KOH 90%, que se necesita para preparar 100 ml de solución 1N.

attashe74 [19]

Answer:

6.23 KOH 90% son necesarios

Explanation:

Una solución 1N de KOH requiere 1equivalente (En KOH, 1eq = 1mol) por cada litro de solución.

Para responder esta pregunta se requiere hallar los equivalentes = Moles de KOH para preparar 100mL = 0.100L de una solución 1N. Haciendo uso de la masa molar de KOH y del porcentaje de pureza del KOH se pueden calcular los gramos requeridos para preparar la solución así:

Equivalentes KOH:

0.100L * (1eq / L) = 0.100eq = 0.100moles

Gramos KOH -Masa molar: 56.1056g/mol-:

0.100moles * (56.1056g/mol) = 5.61 KOH se requieren

KOH 90%:

5.61g KOH * (100g KOH 90% / 90g KOH) =

<h3>6.23 KOH 90% son necesarios</h3>
