An isotope of an element is another element that has the same number of protons but a different number of neutrons (for instance

and

)
D= mass/volume so it's 100/68 which equals 1.47cm3
Answer:
0.0006 mole
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.100 M
Volume = 6.0 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 6.0×10⁻³ L
Thus, moles of potassium iodide :
Moles of HCl = 0.0006 moles
From the reaction shown below:-

1 mole of HCl reacts with 1 mole of sodium carbonate.
So,
0.0006 mole of HCl reacts with 0.0006 mole of sodium carbonate.
<u>Moles of sodium carbonate = 0.0006 moles</u>
Answer:
no.
Explanation:
only one planet would be made gas
is earth. and for what you mean like when
planet would be made of gas my answer is no
because theirs so gravity but im not the one
who's deciding and god is the one who's deciding
if when is the other planet having a gas
i know im wrong
Explanation:
Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself. Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer.
