Chemistry
1 answer:

Answer:

Explanation:

The Key results in the Lab guide are results that justify the reasons to either accept or reject a hypothesis.

To summarize data related to findings in an experiments we make use of diagrams that shows the relationship between the different data.

Although the Lab guide in the question is missing a general answer within the scope of your question is provided above

Key results in an experiment are either milestone results leading to the final result of an experiment or results obtained that might not be part of the experiment but very important to the success of the experiments. therefore results that leads to the acceptance or rejection of a hypothesis in an experiment is a key result.   while

The best way to summarize data related to findings is the use of diagrams. ( graphical representation of the relationships between data contained in an experiment )

Hence we can conclude that use of diagrams is the best way to show the relationship between different data related to experimental findings while key results are results that justifies the acceptance of a hypothesis.

If a sample has 25% parent and 75% daughter, how many halflifes have gone by?
Anit [1.1K]

Answer:

Two half lives.

Explanation:

It is known that the decay of isotopes and radioactive material obeys first order kinetics.

Also, it is clear that in first order decay the half-life time is independent of the initial concentration.

That means for a sample 100% to decay to 50 % it will take one half-life, and to decay the remaining 50% to 25% it will take another half-life.

So, for a sample has 25% parent and 75% daughter it will have two half-lives.

The tiny particles that make up elements are called atoms.<br> True<br> False
raketka [301]
True.
where the atom is the smallest (tiny) particle of an element, the atom may be neutral or ionized, and its size is around 100 picometers. The atom composed of a nucleus and one or more electrons (negative charge) bound to the nucleus, the nucleus contains protons (positive charge) and neutrons.

Alex's teacher showed him a model of gas particles in a sealed container. How should Alex change the model to show the particles
Inessa05 [86]

Answer:

  • Increased volume of particles in the container
  • greater vibration of particles

Explanation:

At higher temperature, the particles of the gas would be more active and vibrate more, or even have greater collisions. Alex can indicate this in the altered model to depict higher temperature.

Consequently, Charles law gives meaning to why there would be an increased volume of gas in the stable pressurized container, if the temperature were to be increased.

I hope this explanation was clear and concise?
