Calculate the mass of the following:
9.11 mol He

Answers

Answer:

36.44 g of He

Explanation:

To convert from moles to grams, you simply multiply by the atomic mass. The conversion table looks like the following:

[tex]\frac{9.11 mol}{1}[/tex] * [tex]\frac{4.00 g}{1 mol}[/tex]

The mol units then cancel, and you are left with 36.44 g of Helium.

Which of the following is the correct Lewis Dot Structure for MgBr2?
PHOTO ABOVE

Answers

Answer:

Option A

Explanation:

To know the correct answer to the question, let us write an equation illustrating the formation of MgBr₂.

This is illustrated below:

1. Magnesium (Mg) is divalent element hence it will lose 2 electrons to form magnesium ion (Mg²⁺) as shown below

Mg —> Mg²⁺ + 2e¯

2. Bromine (Br) is a univalent element. Two bromine atom will receive the two electrons (i.e each atom receives 1 electron) to form the bromide ion (Br¯) as shown below:

2Br + 2e¯ —> 2Br¯

Combine both equation

Mg + 2Br + 2e¯—> Mg²⁺ + 2e¯ + 2Br¯

Cancel out 2e¯

Mg + 2Br —> Mg²⁺ + 2Br¯

Thus we have

Br—Mg—Br

From the illustration made above, we can see that two bromine atom is receiving 1 electron each from the magnesium atom

A sample of ink is put in the center of filter paper . Several drops of ethanol are then put on the ink mark. Two concentric rings of circle are obtained. What is the best conclusion about the ink we can come to? a. It contains two colored substance only b. It contains at least two coloured substances c. It is a compound d. It is broken down by ethanol

Answers

Answer:

The correct option is;

b. It contains at least two colored substances

Explanation:

In chromatography, a mixture is separated into its components, such that in the filter paper, on which the drops of ethanol are then placed on the ink mark, we have different phases of the components of the mixture that have different levels of mobility by capillary action through the filter paper.   Therefore, given that two concentric rings of circles are obtained, we have that each ring is composed of a different component of the mixture and there are therefore, at least two colored substances.

two types of tests you could perform to determine if a substance was a metal or nonmetal.

Answers

Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it’s a ring or chain that turns your skin green, than it is metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal… How can we be sure though?

Granted it can vary given different types of mixed metals, and other materials might share similar characteristics. Characteristics of a given metal can be found like density, which can be determined using volumetric and weight measurements. Other characteristics are also measurable including tensile strength, resistance to impact, flexability. hardness tests, and several others like conductivity and even chemical testing.

Granted other non-metal materials could have similar or even identical characteristics, there are fundamental properties metals have related to their elements. To know which specific metals we have, by heating them we could determine what is in samples by specific and fundamental melting points.

Metals will vibrate and flex to a certain degree, hence their sounds. Given we have a bought or found a metal, we then can measure its corresponding characteristics stated above (tensile strength, density, etc…) by using a variety of micro and macro testing procedures. For example, the characteristic of hardness is easily found by pressing an indentation into a metal and measuring its depth — that's called the Rockwell Method, and there are several others I have still yet to try and discover:)

1.) Nonmetallic elements form ions by (Losing/Gaining) valence electrons in order to complete their outer shell. 2.) The (Fewer/More) valence electrons an element has in its outer shell, the easier it is to complete. 3.) The (FewerMore) electron shells an element has, the easier it is to fill its outermost shell. 4&5.)Reactivity in nonmetals (Increases/Decreases) as you go from left to right in a group, and (Increases/Decreases) as you go from top to bottom.

Answers

Answer:

1) Gaining

2) More

3) More

4) increases

5) decreases

Explanation:

Nonmetals are found towards the right hand side of the periodic table. They form ions by gaining electrons due to the fact that they have more electrons in their outermost shell, hence they only need a few electrons to complete the octet structure.

As the number of shells increases, the outermost shell becomes more populated and easier to fill with electrons.

The reactivity of nonmetal elements generally increases from left to right across the periodic table but decreases from top to bottom down the group.

Answer:

1) Gaining

2) More

3) fewer

4) increases

5) decreases

Describe a few abiotic factors found within the taiga that limit its biodiversity.

Answers

Answer:

Some abiotic factors of the taiga are temperature, precipitation, soil, and sunlight.

Explanation:

emperature affects the taiga because the winter temperature range is -65*F to 30*F (-54*C to -1*C), while the temperature range in the summer is 20*F to 70*F (-7*C to 21*C)

Precipitation affects the taiga because there's some precipitation that falls [30-85 cm. (12-33 in.)].

Soil affects the taiga because there's some acidic and low-in-nutrients soil, and some fertile soil.

Sunlight affects the taiga because there are small amounts of it that reach the ground.

The taiga biome's abiotic components include temperature, sunshine, soil, air, water, etc. Cold arctic air predominates in the taiga environment. The taiga receives more light in the summer, which causes the days to be hotter.

What are abiotic components ?

Abiotic elements, also known as abiotic factors, are non-living chemical and physical elements of the environment that have an impact on the health of living things and the operation of ecosystems. Biology as a whole is supported by abiotic causes and the phenomena that go along with them.

Biotic and abiotic components, such as rainfall, in that order. The taiga is the biggest biome on Earth's surface and features a diversity of migratory and resident creatures. It also has long, cold, and dry winters and short, warm, and moist summers.

The Taiga biome is restricted by four primary criteria. Fire, temperature, the quantity of nutrients in the soil, and sunshine are the four limiting elements. Because certain plants, like the Jack Pine, recover after fire, it is a limiting element in the Taiga biome.

Thus, The taiga biome's abiotic components include temperature, sunshine, soil, air, water, etc.

Balanced chemical equation:

C₂H₄ + 3O₂     →    2CO₂ + 2H₂O

Step 1:

Left side                      Right side

C = 2                           C = 1

H = 4                           O = 3

O = 2                           H = 2

Step 2:

C₂H₄ + O₂     →    2CO₂ + H₂O

Left side                      Right side

C = 2                           C = 2

H = 4                           O = 5

O = 2                           H = 2

Step 3:

C₂H₄ + O₂     →    2CO₂ + 2H₂O

Left side                      Right side

C = 2                           C = 2

H = 4                           O = 6

O = 2                           H = 4

Step 4:

C₂H₄ + 3O₂     →    2CO₂ + 2H₂O

Left side                      Right side

C = 2                           C = 2

H = 4                           O = 6
