In this reaction: Mg (s) + I₂ (s) → MgI₂ (s)

If 2.08 moles of Mg react with 3.56 moles of I₂, and 1.76 moles of MgI₂ form, what is the percent yield?

The scientific question related to the game of basketball is option D: "Do teams that practice more win more games?"

This question is scientific because it explores a cause-and-effect relationship between practice and game outcomes. It can be investigated through empirical observation and data analysis.

To answer this question, researchers could collect data on the practice hours of different basketball teams and compare them to their corresponding game performance. Statistical analysis could be used to determine if there is a correlation between practice time and winning percentage or other performance metrics.

By examining a large sample of teams over an extended period, researchers could draw conclusions about the impact of practice on game outcomes. This scientific inquiry would contribute to the understanding of the factors that influence team success in basketball and could potentially inform training strategies and coaching techniques.

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

Explanation:

Methylene is an organic compound and organic compounds consist of hydrogen atoms and Carbon atoms in n this case Methylene(CH2) has one carbon and two hydrogens .

Answer: methylene doesn't contain CL(chlorine) atoms

Explanation: the chemical formulae for Methylene is CH2

which means it contains only carbon and hydrogen atoms which is 1(one) carbon 2(two)hydrogen atoms

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.

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. I love it very much. I like Physics the most, but other branches are great too.

Answer:

the anode material is graphite(replaceable graphite rods).

The oxygen gas burns away the anode as Carbon dioxide therefore the anode must be replaced continuously.

Answer:

3

Answer:

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).
