Objectives(s):
In your own words, what is the purpose of this lab?

Hypothesis:
In this section, please include the if/then statements 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 composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.

Compound Name Chemical Formula Sodium (Na) Atoms Calcium (Ca) Atoms Hydrogen (H) Atoms Oxygen (O) Atoms Carbon (C) Atoms Chlorine (Cl) Atoms
Ex: Sodium

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.

Using two to three sentences, summarize what you investigated and observed in this lab.
Why do you believe knowing how elements and compounds react together is essential in everyday matters?
Some elements are more "reactive" than other elements; why do you think this is?
Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula.
Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

worked this out and it should be right

Your 20-kg brother Mickey is on a see-saw. If you have a mass
of 50-kg and are 2 meters away from the center of the see-
saw, how far out would Mickey have to sit if he wants to apply
the same force onto you that you apply onto him? meters

Answers

Answer:

Explanation:

To apply the same force as the person, the brother have to sit at a distance of 5 m.

What is meant by torque ?

Torque is defined as the rotational analogue of force. It is the cross product of force and the displacement of the object.

Here,

Mass of the person, m₁ = 50 kg

Mass of the brother, m₂ = 20 kg

Distance of the person, d₁ = 2 m

For the see-saw to get balanced, the torque applied by the two persons each side must be equal.

τ₁ = τ₂

where τ₁ is the torque applied by the person and τ₂ is that applied by the brother.

So, F₁d₁ = F₂d₂

m₁g x d₁ = m₂g x d₂

m₁d₁ = m₂d₂

Therefore, distance of the brother,

d₂ = m₁d₁/m₂

d₂ = 50 x 2/20

d₂ = 5 m

Hence,

To apply the same force as the person, the brother have to sit at a distance of 5 m.

Answers

Answer:

The nephew

Explanation:

The dog's foot prints are overlapping the shoes that are overlapping the tire marks from 3 different tires, if the dog is his seeing dog then it would make sense that the dog's foot prints are next to his and they're going in the same direction, and since the dog's footprints overlap the others it means that they were there last.

People were confused so I'll resay it. The dog is the nephew's seeing dog, so he walks beside him. And if the dog's foot prints are overlapping all of the other's, that means the dog was there after all of the rest of them, and if the nephew is with the dog then the nephew was there last.
