Answer:
I believe its A. Mass
Explanation:
An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. For example, the electrical conductivity of a pure substance is a property that depends only on the type of substance. Silver, gold, and copper are excellent conductors of electricity, while glass and plastic are poor conductors.. Other intensive properties include color, temperature, density, and solubility.
Answer:
The answer to your question is 27 g of Al
Explanation:
Data
mass of Al = ?
moles of Al₂O₃ = 0.5
The correct formula for the product is Al₂O₃
Balanced chemical reaction
4Al + 3O₂ ⇒ 2Al₂O₃
Process
1.- Calculate the molar mass of the product
Al₂O₃ = (27 x 2) + (16 x 3)
= 54 + 48
= 102 g
2.- Convert the moles of Al₂O₃ to grams
102 g ---------------- 1 mol
x ---------------- 0.5 moles
x = (0.5 x 102) / 1
x = 51 g of Al₂O₃
3.- Use proportions to calculate the mass of Al
4(27) g of Al --------------- 2(102) g of Al₂O₃
x --------------- 51 g
x = (51 x 4(27)) / 2(102)
x = 5508 / 204
x = 27 g of Al
Answer:
Ba(OH)2(aq) + CO2(g) = BaCO3(s) + H2O(l)
Reaction type: double replacement
Explanation:
Answer:
The measured absorbance will be too large.
Explanation:
Fe³⁺(aq) + SCN⁻(aq) ⟶Fe(SCN)²⁺(aq)
A = log₁₀(I₀/I)
If the student orients the cuvette so that the path of the light is through the frosted sides of the cuvette, little light will be able to reach the detector.
The measured intensity (I) will be quite small, so the absorbance (A) will be unusually large.
