0.01375 moles of nitric acid (HNO₃) which is the limiting reactant
Explanation:
We have the following chemical reaction:
NaOH + HNO₃ → NaNO₃ + H₂O
Now to determine the number of moles of each reactant we use the following formula:
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume (L)
number of moles of NaOH = 0.5 × 0.250 = 0.125 moles
number of moles of HNO₃ = 0.55 × 0.025 = 0.01375 moles
From the chemical reaction we see that 1 mole of NaOH reacts with 1 mole of HNO₃, so 0.125 moles of NaOH will react with 0.125 moles of HNO₃ but we only have 0.01375 moles of HNO₃ available, so the limiting reactant is HNO₃.

Answer:
I think that Gravity is not considered a gas but it can at the same time
Explanation:
Gasses are affected by gravity, as above video will prove. ... Yes, there is a attractive force between the gas molecules and gravity !
The rest are for sure gases
pH=6.98
Explanation:
This is a very interesting question because it tests your understanding of what it means to have a dynamic equilibrium going on in solution.
As you know, pure water undergoes self-ionization to form hydronium ions, H3O+, and hydroxide anions, OH−.
2H2O(l]⇌H3O+(aq]+OH−(aq]→ very important!
At room temperature, the value of water's ionization constant, KW, is equal to 10−14. This means that you have
KW=[H3O+]⋅[OH−]=10−14
Since the concentrations of hydronium and hydroxide ions are equal for pure water, you will have
[H3O+]=√10−14=10−7M
The pH of pure water will thus be
pH=−log([H3O+])
pH=−log(10−7)=7
Now, let's assume that you're working with a 1.0-L solution of pure water and you add some 10
