Answer:
dark coloured rock with coarse grains in parallel layers
Explanation:
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.
Statue of Liberty - Is do to the sun which made the statue change color.
Bike rust - Is do to being exposed to moisture ( like Water, or any type or liquid.)
Hope this helps!!
<span>8.13 g x 1 mol/126 g = 0.065 moles
0.065 mol/x L = 0.86 M
x = 0.075 liters = 75 mls volume of solution</span>
The two ways that nutrients find their way into the Aquatic ecosystem are nitrogen and phosphorus.
Common examples are ponds, lakes, and rivers, but Aquatic ecosystems also comprehend areas such as floodplains and wetlands, which are deluged with water for all only parts of the year.
