Answer: 16 g of 
reacted with the magnesium
Explanation:
from the equation of reaction: 2Mg + →
48g of Mg requires 32g of O2 to yield 80g of MgO
That is :
48 : 32 : 80
Hence 12 : x: 32
xg of O2 =
= 16 g of
Therefore:
16 g of reacted with the magnesium
Absorbance is unitless by definition, this is the fraction of light absorbed.
Solute concentration will have mol/L units, so it is not unitless.
i/i0 (ratio of emergent to incident intensity) is similar to absorbance, and the units will cancel out, making this unitless.
Path length will have a unit in millimeters or centimeters, so it is not unitless.
Therefore the unitless quantitites are absorbance and intensity ratio.
Answer:
2 : 2
Explanation:
The balanced chemical equation is given as:
2K + Cl₂ → 2KCl
From the balanced reaction equation, we can conclude that;
- 2 moles of K will react with 1 mole of Cl₂
- 2 moles of K will produce 2 moles of KCl
- 1 mole of Cl₂ will produce 2 moles of KCl
Therefore, the mole ratio is 2:2 or 1:1 in the simplest form.
Answer: In this compound, phosphorous and oxygen act together as one charged particle, which is connected to magnesium, the other charged particle.
