Please help! ill make a free point question and brainliest if you answer this right!

Name and Title:

Include your name, instructor's name, date, and name of lab.



Objectives(s):

In your own words, what is the purpose of this lab?



Hypothesis:

In this section, please include the predictions you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.



Procedure:

The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.



Data:

Record the elements present in each unknown astronomical object. Be sure to indicate “yes” or “no” for each element.


Hydrogen Helium Lithium Sodium Carbon Nitrogen

Moon One













Moon Two













Planet One













Planet Two














Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.


1. Using two to three sentences, summarize what you investigated and observed in this lab.

2. Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?

3.If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.)

4.We know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. How does it help us find out the make-up of stars?

5.Why might it be useful to determine the elements that a planet or moon is made up of?

What combination of forces was the closest match? Why?
Virty [35]

Answer: COMBINED FORCES

When forces act in the same direction, they combine to make a bigger force. When they act in opposite directions, they can cancel one another out. If the forces acting on an object balance, the object does not move, but may change shape.

This is my chemistry worksheet. It's a new topic my teacher will barely review with us. Help please???
TEA [102]
So to balance an equation, you need to get the same amount of each type of element on either side of the --> . So you pretty much are given the subscripts in the equations and you need to add coefficients (just normal numbers) in front of any formula that needs it, keeping anything balance.
KCl_{3}  + O_{2}  -\ \textgreater \  KCl_{3}
turns into
2KCl_{3}+ 3O_{2} -> 2KCl_{3}

These coefficient numbers are the molar ratios, so 2 moles of KCl3 for every 3 moles of O2   so 1. 3:2

Then you can use these ratios of find out how many moles of one thing are needed if you are given the amount of another.
\frac{moles of element 1}{cofficient 1}  =  \frac{moles of element 2}{cofficient 2}
and use cross multiplication to solve for whatever you don't know

How can an electron cloud be compared with a spinning airplane propeller? Both represent objects that move in a circular motion
adelina 88 [10]

The answer is that exact locations within either cannot be determined at any given moment in time.

An electron cloud be compared with a spinning airplane propeller in the manner that in both exact location within either cannot be determined at any given moment in time.

In both electron cloud as well as spinning airplane propeller, there is a probability of finding either but exact location can not be determined.
