Answer:
Analyzing data and drawing conclusions
Explanation:
The scientific method is a process or method of inquiry that follows a series of sequential steps which helps a scientist to understand the world around him, draw conclusions and predict results.
The steps in the scientific method include:
1. Observation: the scientist observes his environment keenly and carefully.
2. Asking a question to identify the problem.
3. Conducting research to get information about the problem.
4. Making a hypothesis or an educated guess of a possible outcome.
5.Conducting experiments to test the hypothesis.
6. Analyzing data and drawing conclusions: this involves drawing inferences about experimental results and determining if the collected data supports the original hypothesis and determining if the hypothesis is correct.
7. Communicate results: presenting the result and data through various media, such a laboratory report.

Answer:
There are two explanations to this: covalent network bonding and carbon-silicate cycle.
Explanation:
A network solid or covalent network solid is a chemical compound which is formed through a continued network of atoms or molecules held together by a covalent bond throughout the system. An example included C-C bond in graphite or C-Si bond in silicon carbide (tentative reaction equation below):
xSiO2 + yCO2→ SixCyO(2x+2y)
Si-Si bonds are not as strong as C-C bonds and can easily be displaced as the particles react with atmospheric CO2.
The second scenerio is when silicates such as calcium silicate CaSiO3, or wollastonite, reacts with atmospheric carbon dioxide and water to yield a calcium ion, Ca2+, a bicarbonate ion, HCO3-, and dissolved silica. This process occurs during carbon-silicate cycle and increase organic carbon content:
2CO2 + H2) + CaSiO3 → + SiO2CaCO3 + CO2 + H2)
Answer:
The structures are shown below.
Explanation:
The conjugate base of an acid is the base that is formed when the acid lost a proton (H⁺) in a solution. For a generic acid, HA, the conjugate base is A⁻.
The pyrrole is a base that has a ring with 4 carbons and 1 nitrogen and double bonds between carbons 1 and 2 and between carbons 3 and 4. The nitrogen is between carbons 1 and 4 and has a bond with a hydrogen. When it dissociates, it can lose the hydrogen, and form the conjugate base, which is shown in the picture below. Nitrogen has 5 valence electrons, and in the conjugate base it will do 2 bonds, so it will have 2 lone pairs and 1 free electron.
The cyclopentadiene is formed by a ring of 5 carbons and has double bonds between carbons 1 and 2, and between carbons 3 and 4. When in solution, one of the hydrogens attached in carbons with double bonds will be lost (because it's the more acidic hydrogen, and the structure will be more stable because of the double bond!), so the conjugate base structure is shown below.
