Answer:
Secondary research
Explanation:
Secondary research involves using already existing data, like what can be found in in books, articles, and electronic databases.
A is wrong. Primary research is the research that you do to obtain new information, as in experiments or in interviews and surveys.
B is wrong. Qualitative research is the gathering of non-numerical data.
C is wrong. Summative research is done at the end of a project to determine its success. It can also point the way to future research projects.
Answer:
<em>Rate</em> = k * [C₄H₆]²
Explanation:
It is possible to write the reaction as:
The differential rate law for a simple second order reaction of the type 2A → B is:
With the above information in mind, the rate law for the reaction of butadiene would be:
- <em>Rate</em> = k * [C₄H₆]²
Answer:
Mass is a measure of how much matter an object contains, while weight is a measure of the force of gravity on the object. An object has the same composition, and therefore mass, regardless of its location.
Explanation:
The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.
Explanation:
The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.
It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.
The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.
The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.
For example the structural formula for Methane (CH4)
