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?

valina [46]

Answer:

Major product ethoxide ion

Explanation:

  • Sodium hydride acts as a strong base towards ethanol.
  • Hydride ion abstracts one proton from -OH group in ethanol to produce sodium ethoxide and hydrogen gas.
  • It is an example of acid-base reaction where sodium hydride acts as a base and ethanol acts as an acid
  • Structure of major organic product i.e. ethoxide ion has been shown below.

Which particle has a mass of 9.11 x 10^-28g and charge of -1?
Jet001 [13]

QUESTION:- Which particle has a mass of 9.11 x 10^-28g and charge of -1?

OPTIONS:-

A. electron

B. proton

C. neutron

ANSWER:-

CHARGE ON PROTRON IS +1 AND IT HAS MASS OF 1.6 \times 10  {}^{ - 27} SO IT CANNOT BE URE ANSWER

THERE IS NO CHARGE ON NEUTRON AND HAS MASS ALMOST EQUAL TO THE PROTON SO IT ALSO CANNOT BE URE ANSWER

MASS OF THE ELECTRON:- 9.11 \times 10^{ - 28}

CHARGE ON ELECTRON:- -1

SO URE ANSWER IS ELECTRON

Answer:(1)The urinary system's function is to filter blood and create urine as a waste by-product.

(2) two kidneys we have.

(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.

(4)Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.

(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.

(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.

(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.
