Answer:
Chemical (you should mark me brainliest lol)
Explanation:
Chemical properties can only be measured by changing substances chemical identity.
The balanced equation for the reaction is;
<span>2HNO</span>₃<span> + Ag ---> NO + 2H</span>₂O<span> + AgNO</span>₃
Stoichiometry of HNO₃ to Ag is 2:1
we need to first find the limiting reactant
number of HNO₃ moles - 12.6 g / 63 g/mol = 0.2 mol
number of Ag moles - 10.8 g / 108 g/mol = 0.1 mol
0.2 moles of HNO₃ react with 0.1 mol of Ag, this is in the 2:1 molar ratio which means that both reactants react fully in the reaction.
then molar ratio of Ag to NO is 1:1
number of Ag moles equivalent to number of NO moles
Number of NO moles - 0.1 mol
Mass of NO - 0.1 mol x 30 g/mol = 3 g
mass of NO produced is 3 g
The simplest answer and the correct one is saturated. You can try this at home to see what it looks like. Take a glass and fill it to the 1/2 full mark. Make sure the water is on the coolish side. Start putting measured amounts of salt in the water. Do this until you see salt on the bottom of the glass. The solution is now saturated.
Empty the glass. Put the same amount of water in the glass but make it much warmer. Put the same amount of salt in the glass. It should not be saturated -- that is there should be no salt on the bottom.
So temperature determines saturation. But more important, you should get an idea of what saturation is.
D - density: 1 g/cm³
m - mass: 2,89g
V - volume: ?
----------------------------
d = m/V
V = m/d
V = 2,89/1
V = 2,89cm³
