A Mass Of 2.20 Kg Of Sodium Phosphate Is Converted Number Of Moles
Answer 2

13.41 moles are present in 2.20 kg of sodium phosphate.

What are moles?

A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

The molar mass of sodium phosphate is 163.94 g/mol.

2.20 kg = 2200g

[tex]Moles = \frac{2200g}{163.94 g/mol.}[/tex]

Moles = 13.41954374 = 13.41 moles

Hence, 13.41 moles are present in 2.20 kg of sodium phosphate.

How can the percentage of air be determined

Answers

Answer:

The composition of air can be determined by an experiment which includes passing a known volume of air, measured at a known temperature and pressure, over sufficient amount heated copper granules/powder, and measuring the volume gas remaining after the gas cools down to the temperature at which the first measurement was taken

Oxygen reacts with copper according to the following chemical reaction

2Cu (s) + O₂ (g) → 2CuO (s)

Cupper does not react with the other constituents of air

Whereby the initial volume of air was 100 cm³, we have;

Percentage of oxygen in air = 100 - The final volume reading of the container initially holding the air

When done using am appropriate experimental setup, the percentage of gases remaining equals 79% to 80%, therefore, the percentage composition of oxygen in air is between 20 and 21 percent

I was interested in science when I first saw a diagram of Solar system in my sister's geography book. At that time I was in Senior Kindergarten and she was in 6th grade. At first, I was just interested in space, universe and black holes stuff, but then as I started learning more, I realised how amazing other branches of science are too. They are so systematic. What encourages me to learn more are the gaps in science, its mysteries, I wish to uncover them one day, and for that I am preparing myself. When I am in a science class, I try to imagine where can I apply this knowledge in my day to day life, and my teachers are fascinated when I ask them if this principle is responsible for this phenomena.

Do plants need soil to grow

Answers

Answer:

Not all plants do need soil to grow

Explanation:

Not all plants need soil to grow. Some just do better in soil compared to other growing mediums. What plants need are minerals and nutrients, such as nitrogen, potassium, and phosphorous. Soil is an effective way of delivering those nutrients cost-effectively. You can also use alternative delivery systems like hydroponics, aeroponics, and aquaponics to achieve the desired effect. However, these are only suitable for growing shallow-rooted plants. Plants with deep roots will always need soil, as will larger plants with spreading roots.

El genotipo es el conjunto de información genética en un organismo, y se encuentra codificado en el ADN en su secuencia de bases. Dicha información se expresa mediante síntesis de proteínas.

1.  Los genes son unidades de herencia​ pues almacenan la información genética. El conjunto de genes de una especie se denomina genoma. Cada gen ocupa en el cromosoma una determinada posición, denominada locus. Para cada locus hay dos tipos o formas de genes, llamados alelos. Los mismos pueden ser iguales (siendo el organismo homocigota para ese locus) o distintos (heterocigota). Entonces, la respuesta es "b: Verdadero"

2. Los alelos dominantes, se representan con letras mayúsculas mientras que los alelos recesivos se representan con letras minúsculas. Ejemplo, el alelo que codifica para el color de ojos marrones puede ser dominante (se puede representar con la letra A, por ejemplo), mientras que el alelo que codifica para ojos verdes puede ser recesivo (a). Un individuo cuyo genotipo es Aa, tendrá ojos marrones ya que el alelo dominante enmascara los efectos del alelo recesivo. Un individuo AA también tendrá ojos marrones pues es el único alelo presente. Sin embargo, un individuo aa tendrá ojos verdes ya que tiene ambos alelos recesivos que se expresan. Entonces, la respuesta es "a: Falso"

3. Un cuadro de Punnett es un diagrama utilizado para determinar la probabilidad de obtener descendencia con un determinado fenotipo (características visibles) y genotipo (conjunto de genes). Permite utilizar genotipos maternos y paternos con sus alelos dominantes y recesivos , para cruzarlos y realizar el análisis. Entonces, la respuesta es "b: Verdadero"

4. Mendel realizó un experimento para estudiar los genes de la planta de guisantes. Cruzó una plantas de dos variedades distintas (gigantes y enanas), espolvoreando el polen de una sobre el pistilo de otra. Observó que en la primera generación de descendencia, habían todas plantas gigantes y no de tamaño "intermedio" Luego de esto, entendió que había una característica dominante para el tamaño gigante de una planta, y una recesivo para el tamaño enano. Pero previamente a todo esto, no conocía la dominancia ni el genotipo de los progenitores. Entonces, la respuesta es "a: Falso"

5. Una mutación es una alteración azarosa o por acción de un mutágeno en el ADN, ya sea en su secuencia de bases o en su organización. Esto hace que se produzca una variación en las características del organismo, que puede o no transmitirse a una descendencia. Una mutación genética hereditaria ocurre en las gametas femeninas (óvulo) y/o masculinas (espermatozoide). Cuando ocurre la fertilización, se crea un cigoto que dará lugar a un nuevo organismo que portará la mutación. Entonces, la respuesta es "b: Verdadero"

1. Cruce entre Aa x Aa

siendo A: verde, a: rojo

Cada genotipo, en este caso ambos Aa, representa los genes de un organismo. Sin embargo, en el cuadro de Punnett, se utilizan las gametas producidas por los mismos organismos. Cada gameta solo posee un alelo de cada gen, ya que son haploides. Entonces los organismos con genotipo Aa, pueden producir gametas A o a. (Ver archivo adjunto)

Como se puede ver en el cuadro, hay un 25% de probabilidades de obtener descendencia con genotipo AA (verde), 25% para aa (rojo) y 50% para Aa (verde). Lo mismo se puede expresar como 2:1:1 (de un total de 4, 2 son Aa, 1 es AA y 1 es aa). Recordando que el alelo A es dominante sobre a, la frecuencia fenotípica será de 75% verde y 25% rojo, lo que se puede expresar como 3:1 (de un total de 4, 3 son verdes y 1 es rojo).

Para concluir, recordemos que los genes codifican para las características visibles (fenotipo), y el conjunto de genes forma el genotipo. Para cada gen, hay dos alelos que ocupan un determinado locus o posición en el cromosoma y los mismos pueden ser dominantes o recesivos. Para estudiar esto, se pueden utilizar cuadros de Punnett en donde se cruzan organismos maternos y paternos, conociendo sus genes para así determinar el posible genotipo y fenotipo de la descendencia que puedan tener. Aunque hay que considerar que puede ocurrir una mutación en sus gametas, que se herede y afecte los genes y las características visibles.

If oxygen causes fire to burn, why didn't the world explode when fire burns at a particular place...since oxygen is everywhere...? Explain...​

Answers

Oxygen does not burn. It is not flammable, but it is an oxidizer.

Explanation

I think you are misunderstanding what is meant by "fire burns up air". Fire does use oxygen when it burns. But it also produces carbon dioxide. An oxygen molecule has two oxygen atoms in it. Fires use this to produce carbon dioxide by adding a single carbon atom from the fire’s fuel (wood, for instance).

Vitamin C is a water-soluble vitamin, so your body doesn't store it. You have to get the required amount from your diet (citrus fruits are a great source!), or you could take a daily vitamin C supplement pill. Vitamin C is ascorbic acid, so to determine how much vitamin C (acid) has been placed in each pill, you could do an acid-base titration. One vitamin C pill was dissolved in water and titrated to an endpoint by 16.00 mL of a 0.447 M solution of NaOH. How many grams of ascorbic acid were there in the pill? (MW of ascorbic acid is 176.1 /mol). Explain and show your work.​

Answers

Answer:

1.26 g

Explanation:

Number of moles of ascorbic acid = concentration × volume

Concentration = 0.447 M

Volume = 16.00 mL

Number of moles = 0.447 × 16/1000

Number of moles = 7.152 × 10^-3 moles

Number of moles= mass/molar mass

Molar mass of ascorbic acid = 176.1 g/mol

Mass = 7.152 × 10^-3 moles × 176.1 g/mol

Mass = 1.26 g

How many atoms are in 1g of Hg

Answers

Answer:

7.5275 x 10^21

Explanation:

Answer:

[tex]\boxed {\boxed {\sf 3 \times 10^{21} \ atoms \ Hg}}[/tex]

Explanation:

We are asked to find how many atoms are in 1 gram of mercury.

1. Convert Grams to Moles

First, we convert grams to moles. We use the molar mass or the mass of 1 mole of a substance. These values are equivalent to the atomic masses on the Periodic Table, but the units are grams per mole instead of atomic mass units.

Look up mercury's molar mass.

Hg:  200.59 g/mol

We convert using dimensional analysis, so we create a ratio using the molar mass.

[tex]\frac { 200.59 \ g \ Hg}{ 1 \ mol \ Hg}[/tex]

We are converting 1 gram of mercury to moles, so we multiply the ratio by this value.

[tex]1 \ g \ Hg *\frac { 200.59 \ g \ Hg}{ 1 \ mol \ Hg}[/tex]

Flip the ratio so the units of grams of mercury cancel out.

[tex]1 \ g \ Hg *\frac{ 1 \ mol \ Hg} { 200.59 \ g \ Hg}[/tex]

[tex]1 *\frac{ 1 \ mol \ Hg} { 200.59}[/tex]

[tex]\frac{ 1} { 200.59} \ mol \ Hg[/tex]

[tex]0.004985293385 \ mol \ Hg[/tex]

2. Convert Moles to Atoms

Next, we convert moles to atoms. We use Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units) in 1 mole of a substance. In this case, the particles are atoms of mercury.

We will use dimensional analysis and set up another ratio.

[tex]\frac {6.022 \times 10^{23} \ atoms \ Hg}{ 1 \ mol \ Hg}[/tex]

Multiply by the number of moles we calculated.

[tex]0.004985293385 \ mol \ Hg * \frac {6.022 \times 10^{23} \ atoms \ Hg}{ 1 \ mol \ Hg}[/tex]

The units of moles of mercury cancel.

[tex]0.004985293385 * \frac {6.022 \times 10^{23} \ atoms \ Hg}{ 1 }[/tex]

[tex]3.00214368 \times 10^{21} \ atoms \ Hg[/tex]

3. Round

The original measurement of grams has 1 significant figures, so our answer must have the same. For the number we calculated, that is the ones place. The 0 in the tenths place tells us to leave the 3 in the ones place.

[tex]3 \times 10^{21} \ atoms \ Hg[/tex]

There are approximately 3×10²¹ atoms of mercury in 1 gram of mercury.
