D.Radiation requires a medium to transfer energy.

Answer:

Overexploitation: Human activity and development in the tropical rainforest has lead to massive amounts of forest land being converted into other human uses such as mining or agriculture. Overexploitation of the rain forests Natural resource is a highly damaging impact that humans have on the rainforest, massive amounts of trees are cut down in the rainforest which are used for the timber industry, this cutting down of the trees causes a massive drop in the habitat of the forest’s organisms and the machinery  used to complete this process provide a massive source of pollution and habitat destruction. Approximately 80% of the rainforests nutrients comes from trees and plants. That leaves 20% of the nutrients in the soil. when trees are over exploited conditions change very quickly, the soil dries up and causes erosion. Poaching and hunting are a major issue in the tropical rainforest, exotic creatures are being over hunted causing their populations to go into the danger zones and on the verge of extinction. Furthermore, the rainforest is being used up at an exeptional rate for mining purposes: oil, gold and iron ore are being mined at a massive rate.

Answer:

A and C

Explanation:

Just did the test

The butterflies all live in the same place and the butterflies are all the same species. Hence, options A and C are correct.

A species is often defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.

The butterflies come down at night and gather in clusters. A cluster of butterflies is called a roost or a bivouac. Monarchs migrate alone. They do not travel in flocks the way many birds do.

Hence, options A and C are correct.

Explanation:

Answer:

The amount of water converted from liquid to gas with 6,768 joules is approximately 3.035 g

Explanation:

The amount of heat required to convert a given amount of liquid to gas at its boiling point is known as the latent heat of evaporation of the liquid

The latent heat of evaporation of water, Δ[tex]H_v[/tex] ≈ 2,230 J/g

The relationship between the heat supplied, 'Q', and the amount of water in grams, 'm', evaporated is given as follows

Q = m × Δ[tex]H_v[/tex]

Therefore, the amount of water, 'm', converted from liquid to gas at the boiling point temperature (100°C), when Q = 6,768 Joules, is given as follows;

6,768 J = m × 2,230 J/g

∴ m = 6,768 J /(2,230 J/g) ≈ 3.035 g

The amount of water converted from liquid to gas with 6,768 joules = m ≈ 3.035 g.

Explanation:

The answer should be d) 10, 12, 22

Answer:

The mole and Avogadro’s number are two important concepts of science that provide a link between the properties of individual atoms or molecules and the properties of bulk matter. It is clear that an early theorist of the idea of these two concepts was Avogadro. However, the research literature shows that there is a controversy about the subjects of when and by whom the mole concept was first introduced into science and when and by whom Avogadro’s number was first calculated. Based on this point, the following five matters are taken into consideration in this paper. First, in order to base the subject matter on a strong ground, the historical development of understanding the particulate nature of matter is presented. Second, in 1811, Amedeo Avogadro built the theoretical foundations of the mole concept and the number 6.022 × 1023 mol−1. Third, in 1865, Johann Josef Loschmidt first estimated the number of molecules in a cubic centimetre of a gas under normal conditions as 1.83 × 1018. Fourth, in 1881, August Horstmann first introduced the concept of gram-molecular weight in the sense of today’s mole concept into chemistry and, in 1900, Wilhelm Ostwald first used the term mole instead of the term ‘gram-molecular weight’. Lastly, in 1889, Károly Than first determined the gram-molecular volume of gases under normal conditions as 22,330 cm3. Accordingly, the first value for Avogadro’s number in science history should be 4.09 × 1022 molecules/gram-molecular weight, which is calculated by multiplying Loschmidt’s 1.83 × 1018 molecules/cm3 by Than’s 22,330 cm3/gram-molecular weight. Hence, Avogadro is the originator of the ideas of the mole and the number 6.022 × 1023 mol−1, Horstmann first introduced the mole concept into science/chemistry, and Loschmidt and Than are the scientists who first calculated Avogadro’s number. However, in the science research literature, it is widely expressed that the mole concept was first introduced into chemistry by Ostwald in 1900 and that Avogadro’s number was first calculated by Jean Baptiste Perrin in 1908. As a result, in this study, it is particularly emphasised that Horstmann first introduced the mole concept into science/chemistry and the first value of Avogadro’s number in the history of science was 4.09 × 1022 molecules/gram-molecular weight and Loschmidt and Than together first calculated this number.

Explanation:

A. Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. ... However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.

B. Diamond is hard because the carbon atoms in diamond are bonded in a stronger tetrahedron pattern but graphite is soft and slippery because the carbon atoms in graphite are bonded in layers with only weak vanderwall force holding the layers together.

The average atomic mass : 15.86

Given

205 atoms = 16 amu⇒atom 1

15 atoms = 14 amu⇒atom 2

Required

The average atomic mass

Solution

Total atoms for element Z :

= 205 + 15

= 220 atoms

% atom 1 = 205/220 x 100% = 93.18%

% atom 2 = 15/220 x 100% = 6.82%

The average atomic mass :

= 93.18% x 16 amu + 6.82% x 14 amu

= 14.9088 + 0.9548

The atomic symbol for elements can be found on the periodic table.

The elements in the periodic table are arranged according to their rising atomic number and recurrent chemical characteristics. They are arranged in a tabular format with rows representing periods and columns representing groups.

The sequence of the elements' ascending atomic numbers is left to right and top to bottom. Thus, The valence electron configuration of elements belonging to the same group will be the same, resulting in identical chemical characteristics.

In contrast, valence electrons in the same period will be arranged in ascending order. As a result, there are more energy sub-levels per energy level as the atom's energy level rises. The very first 94 elements of a periodic table are found naturally, whereas the last 95–118 elements have only been created artificially in labs or nuclear reactors.

The periodic table we currently use is a more advanced version of certain models proposed by scientists in the 19th and 20th centuries. Based on the discoveries of those scientists who came before him, like John Newlands and Antoine-Laurent de Lavoisier, Dimitri Mendeleev proposed the periodic table. The periodic table was created by Mendeleev, who is the only person to receive credit for it.

Therefore, the atomic symbol for the elements can be found on the periodic table

Answer:

Percent yield = 90.8%

Explanation:

The reaction of Fe with S to produce FeS is:

Fe + S → FeS

Where the moles of Fe added in excess of S are the moles of FeS

Now, percent yield is defined as 100 times the ratio between actual yield (13.8g of FeS) and theoretical yield (15.2g FeS):

Percent yield = 13.8g / 15.2g * 100
