The solution would be like
this for this specific problem:
Molecular formula of the
two substances: Na2(CO3) and Na(HCO3)
<span>3M * .07L = .21mol </span><span>
<span>1M * .03L
= .03mol </span></span>
<span>.42mol+.03mol = .45mol
Na </span>
30mL + 70mL=100mL or .1L
.45mol/.1L is 4.5M
So the sodium ion concentration is 4.5M. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
Answer:
THERE IS NOTHING MENTION HERE HOW CAN ANYONE KNOW ABOUT IT?]

Answer:
I’m very confused can you clerify that?
Explanation:
Answer: f. 2:2:2:1
Explanation: The reaction is a single displacement where Cs displaces H to pair up with OH.
The balance chemical equation is:
2 Cs + 2 H2O => 2 CsOH + H2
The number of atoms on both sides are equal.
Cs= 2
H= 4
O= 2
A hydrated substance will decrease in mass when heated since the water is being boiled away.
I hope this helps. Let me know if anything is unclear.
