The balance chemical equation is follow,
2 I⁻ + SO₄²⁻ + 4 H⁺ → I₂ + SO₂ + 2 H₂O
According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.
Result:
So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.
Answer:
So we are given with the mass while we are asked for the amount of volume. So this means, we must need an information on the density. From literature, the density of human fat is 0.918 g/cm³. Convert grams to lb by the conversion that 1,000 g = 2.2 lbs.
Density = 0.918 g/cm³ * (2.2 lbs/1,000 g) = 0.0020196 lb/cm³
Volume = Mass/Density = 12.2 lb / 0.0020196 lb/cm³
Volume = 6,040.8 cm³
The number of particles of atoms depends on the ratio of their composition in the compound
<h3>Further explanation</h3>
Given
5.432 g of table sugar
Required
moles of sample
moles of C, H and O
number of atoms
Solution
Table sugar : Sucrose : C₁₂H₂₂O₁₁
= 5.432 : 342,3 g/mol
= 0.016
C = 12 x 0.016 = 0.192
H = 22 x 0.016 = 0.352
O = 11 x 0.016 = 0.176
C = 0.192 x 6.02 x 10²³ = 1.16 x 10²³
H = 0.352 x 6.02 x 10²³ = 2.12 x 10²³
O = 0.176 x 6.02 x 10²³ = 1.06 x 10²³
Answer: We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes
Explanation:
Answer:
The correct option is
C) Trial 1 will have the same calculated empirical formula as trial 2.
Explanation:
The empirical formula is the formula of a chemical compound that states the simplest whole number ratio of each of the atoms included in the compound. It is obtained by dividing the mass of an element present in the compound by the element's molar mass to find the mole ratio of the elements. The obtained mole value for each element is then divided by the smallest number of moles obtained in the division.
By definition the composition and ratio of elements combined in a chemical compound is fixed, therefore trial 1 will have the same calculated empirical formula as trial 2.
