Answer is: 8568.71 of baking soda.
Balanced chemical reaction: H₂SO₄ + 2NaHCO₃ → Na₂SO₄ + 2CO₂ + 2H₂O.
V(H₂SO₄) = 17 L; volume of the sulfuric acid.
c(H₂SO₄) = 3.0 M, molarity of sulfuric acid.
n(H₂SO₄) = V(H₂SO₄) · c(H₂SO₄).
n(H₂SO₄) = 17 L · 3 mol/L.
n(H₂SO₄) = 51 mol; amount of sulfuric acid.
From balanced chemical reaction: n(H₂SO₄) : n(NaHCO₃) = 1 :2.
n(NaHCO₃) = 2 · 51 mol.
n(NaHCO₃) = 102 mol, amount of baking soda.
m(NaHCO₃) = n(NaHCO₃) · M(NaHCO₃).
m(NaHCO₃) = 102 mol · 84.007 g/mol.
m(NaHCO₃) = 8568.714 g; mass of baking soda.
Answer:
Solubility is 1.265g/L
Explanation:
According to Henry's law which states that the solubility of a gas in liquid is directly proportional to the pressure of the gas above the solution.
Sg1 / P1 = Sg2/ P2,
where Sg is the gas solubility, P is the gas pressure.
Sg1 = 0.22
P1 = 20kPA
P2 = 115kPA
Sg2 =?
Sg2 = Sg1 P2 / P1
Sg2 = 0.22 * 115*10^3 / 20*10^3
Sg2 = 25.3*10^3 / 20*10^3
Sg2 = 1.265g/L
the solubility of the gas in water at the new pressure is 1.265g/L
Answer: Option (d) is the correct answer.
Explanation:
Convection is defined as the process in which when heat is supplied to a fluid (liquid or gas) then denser substance (cooler) will sink at the bottom whereas less dense substance (hotter) will rise towards the top.
This intermixing of fluids leads to the generation of convection currents. This macroscopic motion of fluid particles is responsible for convection.
Also, contribution due to the random molecular motion reduces as the flow progresses in perpendicular direction from the surface. Heat transfer is dominated by random molecular motion near the surface where fluid velocity is low.
Thus, we can conclude that out of the given options wrong statement is heat transfer occurs solely due to random molecular motion at the interface between fluid and surface where the fluid velocity is zero.
Oxygen, Nitrogen and Fluorine
Explanation:
In order to participate in a hydrogen bond, a hydrogen atom must be covalently bonded to one of the oxygen, nitrogen and fluorine.
- Hydrogen bonding is a type of dipole - dipole attraction between two specie.
- It is an intermolecular force of attraction.
- This bond type forms when hydrogen is bonded to a more electronegative atom.
- These atoms are oxygen, nitrogen and fluorine
- These species draws the electron shared more to themselves and leaves a partial positive charge on the hydrogen and a negative charge on them.
- The electrostatic force of attraction between the hydrogen of one molecule and the O/N/F of another molecule cause the formation of hydrogen bonds.
