In the formula for carbon tetrahydride, CH4, the percent composition of all elements is:
2 answers:
Answer:
The percentage composition if carbon tetrahydride is 75% of carbon and 25% of hydrogen.
Explanation:
Molecular mass of carbon tetrahydride = 16 g/mol
Atomic mass of carbon = 12 g/mol
Atomic mass of hydrogen atom = 1 g/mol
Percentage of an element in a compound:
Percentage of carbon:
Percentage of hydrogen:
The percentage composition if carbon tetrahydride is 75% of carbon and 25% of hydrogen.

when column B is like the attached pic: (missing in your question)
so the matches will be like that:
1- Qualitative :
as Qualitative is a general or nonspecific observation, they also don't require
measurements and even can't be measured, that is because of the reality is
being approximated only. It describes qualities and uses opinion
2- Hypothesis :
as a hypothesis is an educated guess quantitative, and it is a prediction stated
in " If and then " form. a hypothesis to be valid need a research such as:
-Encyclopedia & state and local research facilities & scientific journals.
3- Direct relationship:
as a Direct relationship is when two variable change in the same direction,
and one remaining larger than the other by the same factory.
- this is a type of a relationship in which there is a change with one variable, and corresponding with the change in the other. and because this corresponding change with the other variable in the same direction so it refers to a positive relationship.
4- Quantitative:
as Quantitative is a measured observation, It's an information or data based
on quantities obtained. And using numbers, equipment and standard units.
5- Control :
as control is standard, reference data or experiment qualitatively. this is what
you compare your experimental results to. This is for comparing results, it
used as a standard for comparison and use baseline measurements to use in
the comparing.
6- Theory :
as Theory is a presently accepted explanation of how something happened.
Scientifically acceptable general principles to explain phenomena. It the
general or abstract principles of the science. for example the wave theory of
light.
7- Law :
as a law is a statement that explains what something does under the same
conditions. when we take about law in science, it is a general rule to explain
the observations in the form of a mathematical statement. Scientific law may
be stated in words or expressed as a mathematical equations.
8- Best fit curve:
as best fit curve is a curve drawn to average the data's deviations direct
relationship. It is a process of constructing a curve that has best fit to a
series of data points.
