Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams
Explanation:
Answer: Sulfuric Acid, H2SO4 is a chemical compound made up of two hydrogen atom, one sulfer atom, and four oxygen atoms.
Explanation:
C) convection cells (currents)
Explanation:
The movement of warmer cooler mantle rocks creating a circulation within the mantle is called a convection cell. These are the forces that drives the plate over asthenosphere.
- Convection is form of heat transfer predominant in liquids and gases.
- The mantle is molten and heated from heat within the core and the decay of radioactive bodies.
- Hot bodies are light and tend to be more buoyant. This causes warm mantle to rise to the surface.
- The cold part are denser and heavier, they sink in the mix.
- This creates pockets of circulation pattern within the mantle called convection cells.

Answer:
sulfuric acid ..............
2 C₁₇H₁₉NO₃ + H₂SO₄ → Product
Moles of H₂SO₄ = M x V(liters) = 0.0116 x 8.91/1000 = 1.033 x 10⁻⁴ mole
moles of morphine = 2 x moles of H₂SO₄ = 2.066 x 10⁻⁴
Mass of morphine = moles x molar mass of morphine = 2.066 x 10⁻⁴ x 285.34
= 0.059 g
percent morphine =
=
= 8.6 %
