TRUE. That type of chemistry is called Stoichiometry, and is a measure of the amount (in mols) of reagents and products. When the reagent is limiting another, it's called "determining the limiting reactant".
In conclusion, the answer is " True"
The state in which the forward reaction rate and the reverse reaction rate are equal. Th concentration of chemicals don’t change
Na (sodium) and Rb (rubidium) have the most similar chemical properties. They're both Alkali metals, found in the first column of the periodic table.
The number of moles of 210 grams of NaHCO₃ is 2.5 moles.
<h3>How to find the Number of moles ? </h3>
To calculate the number of moles use the formula
Number of moles =
Mass of NaHCO₃ = 210 g
Now we have to find the Molar mass of NaHCO₃
= Atomic mass of Na + Atomic mass of H + Atomic mass of C + 3 (Atomic mass of O)
= 23 + 1 + 12 + 3 (16)
= 36 + 48
= 84 g/mol
Now put the value in above formula we get
Number of moles =
=
= 2.5 moles
Thus from the above conclusion we can say that The number of moles of 210 grams of NaHCO₃ is 2.5 moles.
