Answer:
a) H3PO4 (aq) + 3 KOH (aq) → K3PO4 (aq) + 3 H2O (l)
b)
AgNO3 (aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)
c)
Ca(OH)2 (s) + 2 H3PO4 (aq) → Ca(H2PO4)2 (s) + 2 H2O (l)
d)
2 KI (aq) + Pb(NO3)2 (aq) → 2 KNO3 (aq) + PbI2 (s)
e)
3 H2SO4 (aq) + 2 Al(OH)3 (s) → 6 H2O (l) + Al2(SO4)3 (aq)
All balanced equation for each reaction!!
Answer:
The answer is
<h2>1.74 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of magnesium = 11.81 g
volume = 6.80 mL
The density of the metal is
We have the final answer as
<h3>1.74 g/mL</h3>
Hope this helps you
Answer:
NaS2 has two elements within: Sodium & Sulfur.
Basically, the mass percentage of Na2S is:
Sodium = 58.914%
Sulfur = 41.086%
In total, that would equal: 100%.
Explanation:
Well, we know this because Na (Sodium) has 2 atoms & Sodium has no number after it so, that would be an ordinary one atom.
So, knowing that there are more Sodium's than Sulfur, the mass percentage would be higher, than the percentage of Sulfur.
