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.

Great question!

Before genetic engineering, people who needed insulin to survive (diabetics) had to obtain their insulin from pancreases of pigs! When pigs were slaughtered, they removed the pancreas to take out the insulin. Expensive, time consuming - and for jews, not kosher! 

Genetic engineering changed all this - they have cloned the gene for human insulin into a plasmid which they then express in the bacterium Escherichia coli (E. coli). The E. coli makes A LOT of insulin this way - it's made in a stainless steel fermentor (think of how they brew beer) - and it is easily purified. So, now there is human insulin (not pig - so kosher!) and is made fast and cheap!!! No need to slaughter an animal for this anymore!

Answer: Hey! I love space. So I have added all the answers for your questions

Explanation:      1. A blue shift is any decrease in wavelength (increase in energy), with a corresponding increase in frequency, of an electromagnetic wave; the opposite effect is referred to as red shift. In visible light, this shifts the color from the red end of the spectrum to the blue end.

2. This relic radiation is known as the cosmic microwave background radiation. The chemistry of life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the universe was only 10–17 million years old.  

3.  The observations of Edwin Hubble in 1929 suggested that distant galaxies were all apparently moving away from us, so that many scientists came to accept that the universe was expanding.

4. A nebula (Latin for 'cloud' or 'fog'; pl. nebulae, nebulæ, or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases. ... Most nebulae are of vast size; some are hundreds of light-years in diameter.

5. There are three main types of galaxies: Elliptical, Spiral, and Irregular. Two of these three types are further divided and classified into a system that is now known the tuning fork diagram.

6. There are 6 trillion miles in a light-year (approximately), so the distance we need to go is 6 trillion miles / light-year times 4 light-years, or 24 trillion miles. So, this trip would take 1.2 billion hours. There are 24 hours a day and 365.25 days per year, so this time in years is 137 thousand years. Alpha Centauri is 4.367 light years away from Earth.

7. Newton's law of universal gravitation states that two objects are attracted to each other by a force which is proportional to the product of their masses and inversely proportional to the square of the distance between them. ... For the force between two charges and separated by a distance.

8. The other objects are pulled into orbit around the Sun. ... There are eight planets in the Solar System. From closest to farthest from the Sun, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The first four planets are called terrestrial planets

9. The Asteroid Belt is a region between the inner planets and outer planets where thousands of asteroids are found orbiting around the Sun. More than 7000 asteroids have been discovered.

 

10.     Earth's rotation is the rotation of Planet Earth around its own axis. ... Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes, and 4 seconds with respect to other, distant, stars (see below). Earth's rotation is slowing slightly with time; thus, a day was shorter in the past.

11. A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. ... Most of the galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3000 to 300,000 light years) and separated by distances on the order of millions of parsecs (or megaparsecs).  

12. Unlike the outer planets, which have many satellites, Mercury and Venus do not have moons, Earth has one, and Mars has two. Of course, the inner planets have shorter orbits around the Sun, and they all spin more slowly.  

13. How does the Sun cause the seasons? Seasons are caused by the Earth's revolution around the Sun, as well as the tilt of the Earth on its axis. The hemisphere receiving the most direct sunlight experiences spring and summer, while the other experiences autumn and winter.

There you go!
