weqwewe [10]
Al(NO3)3(aq) + 3NaOH(s) --> Al(OH)3 (s) + 3NaNO3 (aq)

The precipitate here is Al(OH)3 (s), since the solid reactant is the precipitate in the aqueous solution. Usually, it is okay to assume in basic chemistry that the transition metal is going to be part of the compound that is the precipitate, especially in an acidic salt and a strong base reaction that we have here.

How many molecules of HCl would react with 1 mole of Mg0?<br> Mg0 +2HCI<br> MgCl, + H,0
Len [333]

Answer:

12.044 ×10²³ molecules of HCl

Explanation:

Given data:

Number of moles of MgO = 1 mol

Number of molecules of HCl react = ?

Solution:

Chemical equation:

MgO + 2HCl       →     MgCl₂  + H₂O

with 1 mole of MgO 2 moles of HCl are react.

Number of molecules of HCl react:

1 mole contain 6.022×10²³ molecules

2 mol × 6.022×10²³ molecules / 1 mol

12.044 ×10²³ molecules
