Answer:
i would say false.
Explanation:
some discoveries are made as people continue exploring the world...........they are just prooved in the laboratory, while there are other which are still made in the lab and are also examined there.
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.
The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
Answer:
Mass = 255 g
Explanation:
Given data:
Number of moles of nitrogen = 7.5 mol
Mass of ammonia formed = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Now we will compare the moles of nitrogen and ammonia.
N₂ : NH₃
1 : 2
7.5 : 2/1×7.5 = 15
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 15 mol × 17 g/mol
Mass = 255 g
Answer:
option 3
Explanation:
Neon is one of the noble gases. Noble gases don't react with any element because of their stability. Elements of Group 18 in Periodic Table are inert gases.
