Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Isotopes have the same number of protons and having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
number of atoms = 11
mass number = 23
number of neutrons=23-11=12
number of atoms = 11
mass number = 24
number of neutrons=24-11=13
This would be measurements.
Answer:
AgCl
Explanation:
The reaction of KCl (In aqueous phase K⁺ + Cl⁻) with AgNO₃ ((In aqueous phase Ag⁺ + NO₃⁻) produce:
Ag⁺ + Cl⁻ ⇄ AgCl(s)
The reaction has a k of 5.56x10¹⁰
That means you will produce 5.56x10¹⁰ molecules of AgCl per molecule of Ag⁺ and Cl⁻ in solution.
As the AgCl is in solid state, this molecules is the precipitate.
I hope it helps!
Answer:
Whichever one of your answer options does not have a molcular formula of C5H12. It's hard for me to tell what the answer options show.
Explanation:
Pentane is a 5-carbon alkane, meaning all carbon atoms are connected by single bonds. In pentane, all the bonds not occupied by carbon atoms are occupied instead by hydrogen atoms. In general, a quikc way of figuring out the molecular formula for an alkane is CnH(n+2), where n is the number of carbon atoms. If you have a molecular formula that does not follow this rule, either there is a different number of carbon atoms, or there is a double or triple bond between carbon atoms such that there are fewer bonds available for hydrogen atoms to occupy.
