Be= Beryllium= weight 9.01
Cl= Chlorine= weight 35.45
Since there are 2 Chlorine, you have to add Chlorine twice.
9.01 + 35.45 + 35.45= 79.91
Answer: 79.91

Correct answer is C
Na2O + H2O ----> 2 NaOH
:-) ;-)
Answer:
C - can be solids, liquids, or gases
Explanation:
Equation: 2H₂ + O₂ → 2H₂O
Now, Given mass of Oxygen = 192 g
Molar mass of Oxygen = 16 g/mol
No. of moles in Oxygen = 16/192 = 0.0833
Now, for every mole of Oxygen, 2 mole of Hydrogen will form,
so, Number of moles of Hydrogen = 0.0833 * 2 = 0.167
Given mass = Number of Moles * Molar mass
Given mass = 0.167 * 2
m = 0.33 g
In short, Your Answer would be: 0.33 g
Hope this helps!
Answer:
This reaction is both precipitation reaction as well as double displacement reaction.
In a double displacement reaction the anions are exchanged and in a precipitation reaction, a precipitate is formed in the end. In this case, AgCl is the precipitate.
