Answer:
The answer to your question is 3.5 moles of I₂
Explanation:
Data
moles of I₂ = ?
moles of KI = 7
Balanced chemical reaction
2KI ⇒ 2K + I₂
Process
To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical reaction for this proportion.
2 moles of KI --------------------- 1 mol of I₂
7 moles of KI -------------------- x
x = (7 x 1) / 2
-Simplifying
x = 7/2
-Result
x = 3.5 moles of I₂
Answer:
SeCl6 + O2——> seO2 + 3Cl2
1. Fructose
2. Proteins
3. Glucose
4. Ribose
5. Galactose.
This is also called sugar, or carbohydrates.
Dalton's theory explained that all matter constitutes of atoms that are indivisible and indestructible. They combine in definite ratios and posses definite masses. He considered atom to be the smallest particles that the matter is composed of. He basically explained about the chemical properties of matter.
After many more researches, it was explained that atom is not the smallest particle that the matter is composed of but it contains many subatomic particles like protons, neutrons and electrons that the matter is made of. Dalton could not explain about the nuclear property of atom.
The frequency of the ray with a wavelength of 3.10 × 10¹⁴ is 9.671 × 10⁻⁷.I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light, ν = frequency and λ= wavelength.
