Why does the reactivity of metals increase from right to left.

Answers

Answer 1

The outer electron shell of all of the noble gases (Neon, Argon, etc) have a complete octet (except helium which only has and only needs two electrons to complete its valence shell) which makes them very stable and nonreactive. The metals on the left (Na, Li, etc) all contain just one electron in their outer shell which makes them unstable and they tend to form ionic bonds.

Note that the column of elements just to the left of the noble gases (the rightmost column save one), the halogens, is also highly reactive, because the halogens all only need a single elecron to form the "stable octet" in the outer shell.

What detail of the myth is suggested in the poem but not in the painting? What connection between the painting's landscape and the myth does this detail convey?.

Answers

The myth shows the moment when the sun melts the wings of Icarus, while the painting does not present this moment. This detail shows that nature contributes to the death of Icarus.

We can arrive at this answer because:

The painting shows only the death of Icarus, showing the moment when he fell into the water and drowned.The purpose of the painting is to show how the universe and all other human beings remained indifferent to Icarus' death.Although the myth also features the death of Icarus, it sets out in more detail.The myth shows why Icarus wanted to use the waxwings and why these wings melted.

The myth focuses on nature's action on the death of Icarus, while the painting reinforces the universe's indifference to this death.

This question is about “Landscape of the Fall of Icarus.”

We are interested in conducting a study in order to determine what percentage of voters of a state would vote for the incumbent governor. What is the minimum size sample needed to estimate the population proportion with a margin of error of +/-0. 06 at 95% confidence?.

Answers

Using the appropriate sample size formula, the minimum number of samples required is 267

Using the relation :

N = [(Z² × pq) / e²] e = Error Margin = 0.06² = 0.0036p = 0.5 q = 1 - 0.5 = 0.5 Zcritical at 95% = 1.96

Substituting the values into the equation :

N = [(1.96² × (0.5 × 0.5)) / 0.0036]

N = (0.9604 / 0.0036)

N = 266.777

N = 267

Hence, the minimum number of samples required is 267

Which of the following best describes the process of translation?.

Answers

Answer:

Translation is a universal process in biology where a protein formed of amino acids is made by using messenger Ribonucleic acid (mRNA) to dictate the order of amino acids. Following transcription (the conversion of DNA into mRNA) an mRNA strand leaves the nucleus and enters the cytoplasm via the nuclear pore.

Explanation:

Your welcome!

Translation is the conversion of genetic information from the language of nucleic acid to protein, hence option 6 is correct.

Ribosomes, which are huge complexes of proteins and RNA, catalyze the translation process. Ribosomes read the RNA transcript and translate it one amino acid at a time into a protein.

Peptide bonds are used to connect the amino acids to produce a polypeptide chain. Following that, the polypeptide chain folds into its ultimate shape, which determines its function.

Translation is the process through which an RNA transcript is converted into a protein. This procedure takes place in the cell's cytoplasm.

Thus, the option 6 is correct.

Un camión traslada 12 vehículos. Algunos son autos y otros son camionetas. Cada auto tiene una masa de 2 toneladas y cada camioneta de 3 toneladas. En total, el camión lleva una carga de 33 toneladas.

Answers

Encontrando y resolviendo un sistema de ecuaciones, veremos que hay 9 camionetas y 3 autos.

Sabemos que hay 12 vehículos en el camión.

Definamos:

a = número de autosc = número de camionetas.

tal que a + c = 12

La masa total será:

a*2 ton + c*3 ton

Y sabemos que el camión lleva 33 toneladas, entonces tenemos:

a*2 ton + c*3 ton = 33 ton

Así encontramos el sistema de ecuaciones:

a + c = 12

a*2 ton + c*3 ton = 33 ton

Para resolverlo, primero aislamos una de las variables en una de las ecuaciones, aislemos a en la primera:

a = 12 - c

Ahora reemplazamos esto en la otra:

(12 - c)*2 ton + c*3 ton = 33 ton

24 ton + c*1 ton = 33 ton

c*1 ton = 9 ton.

c = 9

Es decir, hay 9 camionetas.

Entonces los 3 vehículos restantes son autos.

Hay 9 camionetas y 3 autos.

Determine the minimum mass of hydrogen gas required to produce 226 kj of heat.

Answers

By definition, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.

The reaction is as follows:

2 H₂(g) + O₂(g) → 2 H₂O(g)     ΔH = - 483.5 kJ

In this reaction, you can see that 2 moles of H₂ produces 483.5 kJ of heat. But you want to release 226 kJ of heat.

So you can apply the following rule of three: if 483.5 kJ is released by 2 moles of H₂, 226 kJ of heat is released by when moles of H₂?

[tex]amount of moles of H_{2} =\frac{226 kJx2 moles }{483.5 kJ}[/tex]

amount of moles of H₂= 0.93485 moles

Molar mass is the amount of mass that a substance contains in one mole. In this case, the molar mass of H₂ is 2 [tex]\frac{g}{mole}[/tex].

So, the mass containing 0.93485 moles is calculated as:

0.93485 moles× 2 [tex]\frac{g}{mole}[/tex]= 1.8697 grams

Finally, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.
