Answer:
Ksp=5.5x10^46
Explanation:
Calculate the solubility of Au(OH)3 in water
Mass of water = density x volume
Mass of water = 0.413 x 1
Mass of water = 0.413 g
Energy absorbed = mCpΔT
Energy = 0.413 x 4.184 x 76.5
Energy = 132.2 J
Using Planck's equation:
E = nhc/λ
132.2 = (n x 6.63 x 10⁻³⁴ x 3 x 10⁸) / (13.3 x 10⁻²)
n = 8.84 x 10²⁵ photons
Answer:
The answer to your question is 4.14 g of O₃
Explanation:
Data
mass of nitrogen dioxide = 3.97 g
mass of ozone = x g
Reaction
NO₂ (g) + O₂ (g) ⇒ NO (g) + O₃ (g)
- Check that that reaction is balanced
Reactants Elements Products
1 N 1
4 O 4
This reaction is balanced
- Calculate the molecular mass of NO₂ and O₃
NO₂ = 14 + 32 = 46 g
O₃ = 48 g
- Calculate the mass of Ozone formed.
46 g of NO₂ ------------------ 48 g of O₃
3.97 gof NO₂ ---------------- x
x = (3.97 x 48 ) / 46
x = 190.56 / 46
x = 4.14 g of O₃
Answer:
in the periodic table we can see that the ions of Cl is greater than the ions in Na
Answer:- 2,1
Explanations:- Water is and from it's formula it is clear that the ratio of H to O moles or atoms is 2:1 means two hydrogen atoms for each oxygen atom. No matter what amount of water we have, the ratio of H atoms to O atoms is always same.
Hence, the answer is 2,1.
