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.
I. The solubility of NaCl at 25 degrees C would be between the solubilities at 20 and 30 degrees C. A reasonable answer would be 36 grams/100 g water
ii. From the table, it’s clear that the salts are more soluble at higher temperatures, indicating that an increase in temperature increases solubility.
iii. At 50 degrees C, a saturated ammonium chloride solution will have 50.6 grams of salt per 100 g water. At 20 degrees C, the solution can hold only 37.3 grams of salt per 100 g water. Thus, 13.3 grams of salt will precipitate per 100 grams of water.
The rate of effusion of H₂ : 7.2 x 10⁻² m/s
<h3>Further explanation </h3>
Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
or
MW₁ O₂ = 32 g/mol
MW₂ H₂ = 2 g/mol
Answer:
54 g
Explanation:
We'll begin by calculating the density of X. This can be obtained as follow:
Mass of X = 54 g
Length (L) = 9 cm
Breadth (B) = 2 cm
Height (H) = 1 cm
Volume of X = L × B × H
Volume of X = 9 × 2 × 1
Volume of X = 18 cm³
Density of X =?
Density = mass /volume
Density of X = 54/18
Density of X = 3 g/cm³
Finally, we shall determine the mass of Y as follow:
Length (L) = 3 cm
Breadth (B) = 3 cm
Height (H) = 2 cm
Volume of Y = L × B × H
Volume of Y = 3 × 3 × 2
Volume of Y = 18 cm³
Density of Y = Density of X (since they are made of the same material)
Density of X = 3 g/cm³
Density of Y = Density of X = 3 g/cm³
Mass of Y =.?
Density = mass /volume
3 = mass of Y /18
Cross multiply
Mass of Y = 3 × 18
Mass of Y = 54 g
I think it’s glucose and fructose.
