I dont know if this is right but i think the answer is 10.8 kilometers
Answer:
B. C, A, B
Explanation:
We can measure the age of an artifact by comparison of the activities a living sample with that of the artifact. This is so because the activity of the living sample represents the original activity of the artifact.
So, the steps involved in determining the age of an artifact is to measure the ratio of the parent and daughter nuclei. Then we use the half life of carbon to find out how many half lives have passed. Using this number of half lives that has passed, we can compute the age of the object.
Answer:
1×
Explanation:
To solve this, you will need to do multiple steps.
Firstly, you will have to convert to pOH from pH, which is done by simply subtracting 14-10 to get a pOH of 4.
Then, use the following formula to calculate the [OH-} concentration:
[OH-]= 
When converted to Scientific Notation<u>,</u> you get a resulting answer of
<u>1×</u>

<span>Aluminum foil is a metal so it has the typycal properties of metals. These are the three most representative properties of metals that aluminum foil exhibit:
</span>
<span /><span /><span>
</span><span>1) It is good conductor of electricity: this property is consequence of the metallic bond, which permits that the outermost electrons of each atom can flow through the entire network of atoms conducting the electricity.
</span>
<span /><span /><span>
</span><span>2) Is is good conductor of heat: this other property of metals is due to transmission of vibration that is carried out between neighboring atoms.
</span>
<span /><span /><span>
3) it is ductile: this property means that the metals can be formed into foils.
</span><span />
<span>Other properties that can be mentioned are: solid at room temperature and mallealble (can form wires)
