Cuántos mililitros de agua hay en 3 litros de una botella de naranjas y las solucion tiene una concentracion de 20% v/v

Answers

Respuesta:

2400 mL

Explicación:

Paso 1: Información dada

Volumen de solución: 3 L (3000 mL)Concentración de naranja: 20 % v/v

Paso 2: Calcular el volumen de naranja

La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.

3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja

Paso 3: Calcular el volumn de agua

El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.

VSolución = VNaranja + VAgua

VAgua = VSolución - VNaranja

VAgua = 3000 mL - 600 mL = 2400 mL

Answer:

Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus

Explanation:

Organelles are membrane bound only in eukaryotic ccells.

Prokaryotic cells unlike eukaryotic cells, do not have membrane bound organlles.

Something that is found in both prokaryotic and eukaryotic cells is the cytoplasm, which is fluid that is inside the whole cell.

Unlike eukaryotic cells, prokaryotic cells have loose DNA, which floats around the cell quite literally.

The only way DNA is stored in eukaroyotic cells is in the nucelus, which is only found in eukaryotic cells, not prokaryotic.

Si en un planeta la presión atmosférica es mayor que 5,1 atm terrestres, los habitantes podrían nadar en ríos de dióxido de carbono líquido?

Answers

Answer:

Los habitantes del planeta con una atmósfera superior a 5,1 atm de la Tierra, no estarían nadando en ríos de dióxido de carbono líquido

Explanation:

De las tablas de datos termodinámicos, la presión a la que el vapor de dióxido de carbono está en equilibrio con su estado líquido a una temperatura ambiente de 25 ° C es 6,401 kPa, lo que equivale a 63,17296 atm.

Por lo tanto, a una presión de 5.1 de la atmósfera terrestre, el dióxido de carbono es completamente gaseoso y los habitantes del planeta con una presión atmosférica de 5.1 atm de la Tierra todavía observarían solo hidrógeno gaseoso y no estarían nadando en ríos de dióxido de carbono líquido.

What term is used by chemists to quantitatively describe a solution in which a relatively small amount of solute is dissolved?

Answers

A dilute solution is one that has a relatively small amount of dissolved solute. However, these terms are relative, and we need to be able to express concentration in a more exact, quantitative manner. Still, concentrated and dilute are useful as terms to compare one solution to another.

A hot, gas-like mixture with no definite volume or shape that is made up of electrically charged particles is _________. * 1 point

Answers

Answer:

Plasma

Explanation:

In addition to solid, liquid and gas, there exists a fourth state of matter called the plasma.

Plasma is a state of matter involving super=heated matter such that electrons leave atoms thereby leading to the formation of an ionized gas.

In summary, plasma is a hot, gas-like mixture with no definite volume or shape that is made up of electrically charged particles.

what is the name of the compound that forms when aluminum and Thiocyanate combine?

Answers

Answer:

The correct answer is - Aluminum Thiocyanate.

Explanation:

When aluminum and thiocyanate combine the new compound form, is called Aluminum Thiocyanate. Al(SCN)3 is the chemical formula that represents this Aluminum Thiocyanate compound.

This compound is formed by a synthesis reaction where aluminum is combined with thiocyanate:

Al3 + 9 SCN = 3 Al(SCN)3

Thus, the correct answer is - the name of the compound is Aluminum Thiocyanate.

the sparks.

Answers

By thinking, these sparks are produced. In your essay, describe a time when you saw sparks and make an effort to identify the factors that contributed to it.

What is the spark like?

Spark perfectly encapsulates an user's character and desired mode of interaction with the outside world. Happiness and optimism are spread by sparks. To produce an instantaneous electrostatic force known as just an electric spark, a sufficiently strong electromagnetic current must establish an electrically conducting conduit through a typically insulating medium, typically air as well as other gases or gas mixtures.

How do combinations work?

When two or more compounds combine to create a single new substance, this reaction is called a combination reaction.

Determine the concentration of strontium ions in saturated solution of strontium sulfate, SrSO4, if the Ksp for SrSO4 is 3.2x10-7.

Answers

Answer:

[tex][Sr^{2+}]=5.66x10^{-4}M[/tex]

Explanation:

Hello there!

In this case, given the solubility equilibrium of strontium sulfate:

[tex]SrSO_4(s)\rightleftharpoons Sr^{2+}(aq)+SO_4^{2-}(aq)[/tex]

Whose equilibrium expression is:

[tex]Ksp=[Sr^{2+}][SO_4^{2-}][/tex]

In such a way, we can introduce the molar solubility, s, in the equation to obtain:

[tex]Ksp=s*s=s^2\\\\3.2x10^{-7}=s^2[/tex]

Then, we apply the square root to obtain:

[tex]s=\sqrt{3.2x10^{-7}}\\\\s=5.66x10^{-4}M[/tex]

Which is also the concentration of strontium ions:

[tex][Sr^{2+}]=5.66x10^{-4}M[/tex]

Explain why world food shortages could be reduced by growing more algae.

Answers

One of the many awe-inspiring things about algae, Professor Greene explains, is that they can grow between ten and 100 times faster than land plants. In view of this speedy growth rate – combined with the fact they can thrive virtually anywhere in the right conditions – growing marine microalgae could provide a variety of solutions to some of the world’s most pressing problems.

Take, global warming. Algae sequesters CO2, as we have learned, but owing to the fact they grow faster than land plants, can cover wider areas and can be utilised in bioreactors, they can actually absorb CO2 more effectively than land plants. AI company Hypergiant Industries, for instance, say their algae bioreactor was 400 times more efficient at taking in CO2 than trees.

And it’s not just their nutritional credentials which could solve humanity’s looming food crisis, but how they are produced. Marine microalgae grow in seawater, which means they do not rely on arable land or freshwater, both of which are in limited supply. Professor Greene believes the use of these organisms could therefore release almost three million km2 of cropland for reforestation, and also conserve one fifth of global freshwater

Why do plants need sunlight for photosynthesis?

Answers

Explanation: Plants using photosynthesis will take in carbon dioxide from the air, bring up water from the roots, and use sunlight as the energetic source to create sugar from water and carbon dioxide. Plants contain a molecule called chlorophyll, and the chlorophyll is what absorbs the sunlight

The answer is Without the sun, plants wouldn't get the necessary food needed to grow, reproduce, and survive. Plants need three basic things to live: sunlight, water, and carbon dioxide. Through a process called photosynthesis, the plants use the energy from the sun to convert carbon dioxide, soil nutrients, and water into foods Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.
