Once you have constructed an effective hypothesis, the next step in the scientific inquiry process is to
test the hypothesis through experimentation. This is a great opportunity for students to start a science
notebook, if they have not yet started recording their progress.
Steps to Identifying and Conducting an Appropriate Experiment to Test a Hypothesis
1) Present Hypotheses
Make a list of all potential hypotheses to be tested.
2) Make Predictions
For each hypothesis, ask what would be true if the hypothesis were true.
3) Write the Experimental Procedure
The experimental procedure is a step-by-step recipe for the science experiment. A good
procedure contains enough detail that someone else could easily duplicate the
experiment. Once you have formed a hypothesis, you will need to develop your
experimental procedure to test whether your hypothesis is true or false.
4) Identify the Independent and Dependent Variables
The first step of designing the experimental procedure involves planning how to change
the independent variable and how to measure the impact that this change has on the
dependent variable. To guarantee a fair test when conducting the experiment, make sure
that the only thing changing is the independent variable. All controlled variables must
remain constant.
5) Design the Experiments
How can you identify an appropriate experiment that will effectively test your
hypothesis? Begin by asking yourselves, “What can I do that will give me one result if my
hypothesis is true, and a different result if my hypothesis is false?” Design at least one
possible experiment for each hypothesis. Be sure that each experiment tests only one
hypothesis.
The most abundant isotope is Gz-83 because the average atomic mass of Gz is closer to 83.
The average atomic mass is defined as the weigthed mean of the isotopes.
The mass of the isotopes is 80, 81 and 83 uma, respectively.
As the average atomic mass (82.74uma) is closer to the atomic mass of Gz-83 than the mass of the other isotopes, you can interpretate that the most abundant isotope is Gz-83.

The answer is adduction lol
A Cell with few energy needs would most likely contain a small number of Mitochondria.
- All cells require energy to function, but cells typically have significant energy needs that can only be met by the mitochondria, the cell's powerhouse.
- They transform glucose into ATP, a chemical with a huge energy storage capacity.
- Muscles have a large number of mitochondria, allowing them to react rapidly and powerfully to the body's ongoing need for energy.
- Macromolecules, defunct cell components, and microbes are all digested by lysosomes.
- Vacuoles are typically tiny and aid in the sequestration of waste.
- The ribosome, an intercellular structure consisting of both RNA and protein, is where a cell produces new proteins.
Therefore out of all these cell organelles, the cell has fewer mitochondria for less energy need.

The mass of sodium chloride at the two parts are mathematically given as
- m=10,688.18g
- mass of Nacl(m)=39.15g
<h3>What is the mass of sodium chloride that can react with the same volume of fluorine gas at STP?</h3>
Generally, the equation for ideal gas is mathematically given as
PV=nRT
Where the chemical equation is
F2 + 2NaCl → Cl2 + 2NaF
Therefore
1.50x15=m/M *(1.50*0.0821)
1-50 x 15=m/58.5 *(1.50*0.0821)
m=10,688.18g
Part 2
PV=m'/MRT
1*15=m'/58.5*0.0821*273
m'=39.15g
mass of Nacl(m)=m'=39.15g
