Answer:
molar mass has unit of g/mol so it's usually calculated by taking mass divide by number of moles
but usually, molar masses are given in periodic table itself
Answer:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Explanation:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Halogens are Soluble
Carbonates are Insoluble
This reaction DOES take place.
Answer:
C
Explanation:
While some dilute acids are said to be weak, some are said to be strong. Now, the principal basis for this classification is based on the extent of ionization in water.
While strong acids ionize completely to give the maximum number of Oxonium ions, weak acids only ionize to an extent and thus do not give the full needed oxonium ions. Hence , we say they gave only a fraction and we term the ionization partial or incomplete.
Asa weak acid, nitrous acid is expected to ionize slightly and not completely. This makes it produce only a fraction of the expected oxonium ions in water
Answer:
0.39 moles
Explanation:
To find how many moles are in 50.0 g of CaC₂O₄ you divide the grams of the sample by the molar mass of the compound;
=0.39 mol
The grams cancel out and you are left with moles!
I hope this help ^-^
