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.
Answer: -
If a gas at 250 K has a pressure of 0.00008 Pa and the pressure drops to 0.00002 Pa, 62.5 K is the new temperature
Explanation: -
Initial Pressure P₁ = 0.00008 Pa
Final Pressure P₂ = 0.00002 Pa
Initial Temperature T₁ = 250 K
Since the volume is not mentioned, it remains constant.
So initial Volume V₁ = Final volume V₂
Now using the combined gas equation
=
Final Temperature T₂ =
Plugging in the values,
T₂ =
As V₂ = V₁, they cancel each other.
T₂ = 62.5 K
<span>There are many different kinds of clouds all around us. Clouds come in diverse shapes and colors. Some clouds are fluffy and others are wispy. Some clouds float high in the sky and others sit low on the ground. Some clouds warn of storms and other clouds tell of fair weather. Compare and contrast the characteristics of different types of clouds through vibrant photographs.</span>
A change in temperature or color are two signs that a chemical reaction has taken place.
hydrogen is not balanced
the right balanced equation is
Fe2O3 + 3 H2 -> 2Fe + 3H2O
