Answer:
In general an acid reacts with a carbonate or hydrogen-carbonate to produce a salt, carbon dioxide gas and water.
Answer:

Explanation:
The first step in this reaction is the<u> converstion from Kg</u> of
<u>to</u> <u>grams</u> of
.


Then we can calculate the <u>percentage</u> of
in the sample:


Answer:
reactant
Explanation:
I watched a chem video and this is what they called it.
There are 5.43 x 10²³ present in 187 grams of XeF₄
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass

mass of XeF₄ = 187 g
mol XeF₄ (MW=207,2836 g/mol) :

Number of molecules :
