Answer:

Scientists estimate that the human genome, for example, has about 20,000 to 25,000 protein-coding genes. ... In fact, compared to almost any other organism, humans' 25,000 protein-coding genes do not seem like many. The fruit fly Drosophila melanogaster, for example, has an estimated 13,000 protein-coding genes.

Answer:

CH3CH2OH

Explanation:

The reactant has:

- 6 carbon atoms

- 12 hydrogen atoms

- 6 oxygen atoms

The second product has:

- 4 oxygen atoms

- 2 carbon atoms

In 2CH3CH2OH there are:

- 4 carbon atoms

- 12 hydrogen atoms

- 2 oxygen atoms

If you combine the number of atoms of each chemical species of both 2CH3CH2OH and the second product, you will see that you get the same number of atoms of each chemical species in the reactant:

carbon = 2 + 4 = 6 (number of carbon atoms in reactant)

oxygen = 4 + 2 = 6 (number of oxygen atoms in reactant)

hydrogen = 0 + 12 = 12 (number of hydrogen atoms in reactant)

This means that no atoms were created or destroyed which is true for all equations. If this was done with one of the other compounds listed, atoms would have been created or destroyed which cannot happen. In all equations, atoms are never created or destroyed, however they do rearrange to form new products.

Answer:

Ice act and help in condensation of the vapor

Explanation:

The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. Latent heat from condensation causes an increase in air temperature surrounding the water droplets. The warmer air rises, causing the water vapor to condense when it meets cooler air at a higher altitude

C.) Nitrogen Cycle

Nitrogen moves continuously between the atmosphere and soil in what is called the nitrogen cycle.

Explanation:

The nitrogen cycle is the biogeochemical cycle describing how nitrogen moves through the biosphere and atmosphere. The nitrogen cycle is a lot like the carbon and water cycle. Rainstorms contribute atmospheric nitrogen through raindrops that reach the soil. Plants, such as soybeans, alfalfa, and clovers, are plants that can convert atmospheric nitrogen into plant-usable nitrogen.

Based on the given concentration and volume of solutions, the molarity of the ions are as follows:

The molarity of a solution is the number of moles of the substance in a given volume of solution in litres.

Moles of [BrO3-] = 0.04M × 0.005 L = 0.0002 moles

Moles of [I-] = 0.01 M × 0.005 L = 0.00005 moles

Moles of [H+] = 0.1 M × 0.005 L = 0.0005 moles

Flask A:

total volume = 15 mL = 0.015 L

Molarity of [I-] = 0.00005/0.015

Molarity of [I-] = = 0.0033 M

Flask B:

Total volume = 10 mL = 0.01 L

Molarity of [BrO3-] = 0.0002/0.01

Molarity of [BrO3-] = 0.02 M

Molarity of [H+] = 0.0005/0.01

Molarity of [H+] = 0.05 M

Answer:

How many grams of H2 can be produced from the reaction of 11.5 grams of sodium with an excess of water? Hint: 2Na + 2H2O ---> 2NaOH + H2. Ans: 0.505g .

Explanation:

This problem is providing us with the percent composition of a compound containing magnesium, nitrogen, oxygen and water. Thus, the empirical formula is required and found to be Mg(NO₃)₂·6H₂O.

In chemistry, empirical formulas are used in order to figure out the minimum whole-number representation of a molecular formula, which contains the actual number of atoms.

Thus, we start determining it by assuming the given percentages as masses and calculating the moles with the atomic or molar mass of the involved species:

[tex]n_{Mg}=\frac{9.37}{24.3} =0.386\\\\n_{N}=\frac{10.3}{14.01}=0.735\\ \\n_O=\frac{37.52}{16.00}=2.32\\ \\n_{H_2O}=\frac{42.18}{18.02}=2.34[/tex]

Next, we divide by the 0.386 as the smallest number of moles in order to determine their subscripts in the chemical formula:

 [tex]Mg}=\frac{0.386}{0.386} =1\\\\n_{N}=\frac{0.735}{0.386}=2\\\\n_O=\frac{2.32}{0.386}=6\\\\n_{H_2O}=\frac{2.34}{0.386}=6[/tex]

Hence, the empirical formula turns out to be Mg(NO₃)₂·6H₂O, which is actually a hydrate (hexahydrate).

Answer:

    All species in a given region interact with all nonliving objects to form an ecosystem. Animals, plants, and bacteria are examples of living organisms. Water, soil, rocks, and the sun are all nonliving objects. Biotic components are living organisms, while abiotic components are nonliving organisms.

    Biotic components come in a variety of shapes and sizes. Producers are living entities that convert the sun's energy, water, and carbon dioxide into fuel through a process called photosynthesis. Producers create the compounds that underpin all life on Earth, including plants, algae, and bacteria.

Explanation:

O₂ reacts increasing the NO₂ to 0.718 moles. At the return to equilibrium,

the amount SO₃ in the container approximately 0.931 moles.

The equilibrium constant for the reaction aA + bB ⇌ cC + dD is presented as follows;

[tex]K_c = \mathbf{\dfrac{[C]^c_{eq} +[D]^d_{eq} }{[A]^a_{eq} +[B]^b_{eq} }}[/tex]

The equilibrium constant for the reaction, whereby the volume is same for the contents is therefore;

[tex]K = \dfrac{0.654 \times 0.718}{0.369 \times 0.369} \approx 3.45[/tex]

Given that the NO reacts with the O₂ as follows;

2NO + O₂ [tex]\longrightarrow[/tex] 2NO₂

We have;

The number of moles of NO₂ added = 0.718 moles

The new number of moles are therefore;

Which gives;

0 = (0.654 + x) × x - 3.45 × (0.369 × (0.369 + 0.718)

2.45·x² - 5.6772·x + 1.384 = 0

[tex]x = \dfrac{5.6772 \pm \sqrt{(-5.6772)^2 - 4 \times 2.45 \times (1.3834)} }{2\times 2.45}[/tex]

x ≈ 0.2768 or x ≈ 2.04

The possible number of moles of SO₃ in the container after equilibrium is reestablished is therefore;

n ≈ 0.654 + 0.2768 ≈ 0.931
