Answer;

-Biochemist

Explanation;

Biochemistry is the study of the chemical reactions that take place within living cells. These includes photosynthesis in plants, thus a biochemist studies chemical reactions involving photosynthesis.

Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

From what group must the terminal atoms come in an abx molecule where the central atom is from group 6a, for the electron-domain

Anni [7]

First of all, I need to complete some missing parts of the question, so here I copy it.

From what group must the terminal atoms come in an ABₓ molecule where the central atom is from group 6a, for the electron-domain geometry and the molecular geometry to both be trigonal planar

Answer:

Group 6a (a.k.a group 16).

Explanation:

In the molecule ABₓ, x a subscript.

A<em> trigonal planar molecule</em> is a symmetric molecule with one atom in the centre surrounded by three atoms, all in the same plane, forming a triangle with bond angles equal to 120°.

In this case we want the central atom to be oxygen, so our molecules must be of the kind AB₃, where A is the central atom, from group 6a, and B represents the terminal atoms.

Group 6a is the group of O, S, Se, Te, and Po. The atoms of these elements have 6 valence electrons.

So, the central atom will have 6 valence electrons. To be symmetrical, this central atom will have three pairs of electons separated 120°.

So, each of the terminal atoms must be willing to form covalent bonds by with two electrons, which means that, to meet the octet rule, the terminal atoms must have 6 electrons each. Thus, the terminal atoms also must have 6 valence electrons, and you conclude that they belong to the same group 6a (or group 16 as per the modern periodic table).

One example of these kind of compounds is SO₃.

Explain two advantages and disadvantages of using energy created by nuclear fission and nuclear fusion.

alisha [4.7K]

A. NUCLEAR FUSION is the combination of two atomic nuclei in order to create an atom that in turn creates energy.

A.1 DISADVANTAGES

1. Expensive Construction Costs- To be able to put up such powerhouse, it needs ostentatious financial support to create a facility and gather experts and scientists.

2. Energy Input vs Energy Output- To be able to fuse the two nuclei together, there is a great demand for high levels of heat. Thus to be able to produce large amount of energy, it also needs a large amount of thermal energy which is not reasonable enough.

A.2 ADVANTAGES

1. Barely Any Waste- the only by product of nuclear fusion is helium and it is non toxic. This does not cause any harm to the environment and to people.

2. Unlimited Fuel- All of the components needed to produce energy can be made. Deuterium, which is the main ingredient needed to supply a truly unlimited and sustainable energy supply, can be distilled from the sea water.

B. NUCLEAR FISSION- refers to the process of splitting of the nucleus of an atom into several smaller particles to produce free neutrons and lighter elements.

B.1 DISADVANTAGES

1. It can be dangerous for employees- Radiation which is one of the byproducts of nuclear fission can be harmful to the personnel working within its premises.

2. It has high initial expenses- Nuclear power plants needs a specialized equipment for it to become functional.

B.2 ADVANTAGES

1. It helps minimize environmental pollution- Nuclear power plants can produce large amounts of energy while consuming relatively minimal amount of fossil fuel. To explain further, consumption and usage of fossil fuel poses adverse effect in the environment because it can emit carbon dioxide and other harmful chemicals.

2. It helps reduce global warming- If the world would opt for nuclear fission, then there would be less greenhouse gasses in the atmosphere. This in turn would mitigate global warming.

Calculation: If a compound is 14.40% hydrogen by mass and 85.60% carbon by mass, what is the empirical formula?

IgorLugansk [536]

Answer:

CH2

Explanation:

We are given that a compound is 14.40% hydrogen and 85.60% carbon.

Let the mass of the substance be 100g.

Mass of the hydrogen: 14.40% of 100 = 14.40 g

Mass of the carbon: 85.60% of 100 = 85.60 g

Now, let's find the moles of hydrogen:

$14.40 g*\frac{1 mole}{1gH} = 14.40 mole$

Moles of carbon:

$85.60g*\frac{1 mol}{12gC} = 7.13mol$

Let's put these in a ratio and simplify:

7.13 mole C: 14.40 mole H

1 mole C: 2 mole H

Therefore, the empirical formula of this compound is CH2.

Hope this helps!! If you have any questions about my work, please let me know in the comments!
