How does an underestimate relate to rounding factors before estimating?

Biology
1 answer:
Mashutka [201]3 years ago
3 0
<span>If factors are only rounded up, then the estimate is an overestimate. If factors are only rounded down, then the estimate is an underestimate. When some factors are rounded up and some are rounded down, it is harder to tell whether the estimate is an overestimate or an underestimate.</span>

Cual es la diferencia entre gemelos y mellizos
ivanzaharov [21]

Answer:

Los gemelos fraternos son "dicigóticos", lo que significa que se desarrollaron a partir de dos óvulos diferentes fertilizados por dos espermatozoides diferentes, mientras que los gemelos idénticos son "monocigóticos", es decir, se desarrollaron a partir de un solo óvulo fertilizado que se dividió.

Una solución de 0.204 M de NaOH seutiliza para neutralizar 50 mL de una solución de H3PO4. Si se necesitaron 16.4 mL de la soluc
vfiekz [6]

Answer: 0.05 M

Explanation:

Para responder esta pregunta, hay que tener en cuenta la Ley de Conservación de la Masa. <u>La misma indica que en una reacción química en un sistema cerrado, la masa total de las moléculas que participan permanece constante.</u> Esto significa que la masa utilizada en los reactivos es la misma que la masa de los productos generados.

En este problema, se cuenta con una solución de NaOH (hidróxido de sodio) tiene una molaridad de 0.204 (siendo la molaridad el número de moles por litro de solución) y se utilizan 16.4 mL de dicha solución para agregarla a 50 mL de una solución de H3PO4 (ácido fosfórico).

Entonces, ya que la masa de ambas soluciones no se pierde, podemos utilizar la ecuación de la Ley de Conservación de la Masa:

Concentración inicial x Volumen inicial = Concentración final x Volumen final.

Concentración inicial: 0.204 M

Volumen inicial: 16.4 mL

Concentración final: ?

Volumen final: 50 mL + 16.4 mL = 66.4 mL

Reemplazamos los valores en la ecuación:

0.204 M x 16.4 mL = Concentración final x 66.4 mL

La molaridad de la solución de H3PO4 es de 0.05 M.

Which of the following correctly demonstrates how an anatomist and a physiologist might describe components of the eye?
stiks02 [169]
An anatomist studies the parts of the body by looking at the physical components of the that body part and identifying its functions. A physiologist looks at the mechanism at how a body part functions. The components of the eye according to an anatomist would be based on the different physical components of the eye while to a physiologist, the components would be based on the functions.
