Answer:
0.875 time.
Explanation:
The length of plastic water bottles are bought in the United States every day = (the no. of plastic water bottles are bought every day)(length of each bottle) = (140.0 million bottle)(0.25 m) = 35.0 million meter.
The length of the equator of the earth = 40.0 million meter.
∴ The times can the Earth's equator be circled by a line of plastic bottles used in the United States every day = (The length of plastic water bottles are bought in the United States every day)/(The length of the equator of the earth) = (35.0 million meter)/(40.0 million meter) = 0.875 times.
Answer:
They have fewer hydrogen atoms attached to the carbon chain than alkanes
Explanation:
Let's compare ethane (an alkane) with ethene (an alkene) and ethyne (an alkyne):
- Ethane's formula is C₂H₄, while ethene's is C₂H₄ and ethyne's C₂H₂.
As you can see, alkenes and alkynes have fewer hydrogen atoms attached to the carbon chain due to them having multiple bonds between the carbon atoms.
They have a nucleus and its organelles in common.
Boiling point
Explanation:
The likely dependent variable the student used in this experiment is boiling point temperature
The amount of heat supplied will determine when a substance will boil or not based on the intermolecular force in them.
- In an experiment, the dependent variable is treated as the effect produced.
- It is the variable that relies on the outcome of the experiment.
- The independent variable is responsible for the changes in the experiment.
- The cause is the independent variable. It does not rely on the outcome of the experiment.
- The dependent variable is the boiling point.
- The independent variable is the amount of heat supplied or temperature changes.

An ionic compound is a substance that contains atoms that are bonded together through an ionic bond, where electrons are transferred from one atom to another. For the given experiment above, the material that is missing from the list is WATER or solvent. It is necessary because conduction through water will help you identify if a sample compound is ionic through its electrolytes. <span>Ionic compounds that are soluble are typically electrolytes</span>
