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
<h2>
Answer</h2>
The answer is 38.05 years
<h2>
Explanation</h2>
To solve this question, we should convert the given seconds to the year.
So,
Number of seconds in a year =
Seconds the man lived = .2 * 10^9
How many years, he lived = ?
Here a unit method will be applied as
Total years the man lived=
Total years the man lived = 38.05 years
Components in a mixture don’t chemically react while compounds do chemically react and some of their original properties may be lost. A solution is when the solute mixed with the solvent.
Answer:
5.10
Explanation:
HCN ⇄ H⁺ + CN⁻
of HCN = 6.2 × 10⁻¹⁰ ;
molar solution of sodium cyanide [HCN] = 0.10M
∴ the pH of 0.10 molar solution of which contains the cyanide ion can be calculated as:
=
= 7.874 × 10⁻⁶
∴pH = -log {7.874 × 10⁻⁶}
= 5.10
