Answer:

5.56 × 10^23 molecules

Explanation:

The number of molecules in a molecule can be calculated by multiplying the number of moles in that molecule by Avagadro's number (6.02 × 10^23)

Using mole = mass/molar mass

Molar mass of N2O4 = 14(2) + 16(4)

= 28 + 64

= 92g/mol

mole = 85.0/92

= 0.9239

= 0.924mol

number of molecules of N2O4 (nA) = 0.924 × 6.02 × 10^23

= 5.56 × 10^23 molecules

What kinds of things on earth are made of cells?

Lena [83]

Answer:

All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms.

Explanation:

Aqueous hydroiodic acid reacts with liquid water in a reversible reaction.

2 HI + 2 H₂O ⇔ 2 H₃O + I₂

This is an acid-base reaction. HI is the acid, and H₂O is the base. The conjugate acid is H₃O, and the conjugate base is I₂. You can figure out the acid and base by a using a table of strong/weak acids and bases. The conjugate will have one less or one more H⁺ depending on if it's an acid or a base.

The expression for Kₐ of the reaction is below. You have to put the acid and its conjugate base on the top and the base and its conjugate on the bottom. I didn't put in H₂O since, although it is the base in this equation, it isn't really a base.

$K_{a}=\frac{[HI][H_{3}O] }{[I_{2}] }$

Solid zinc reacts with solid manganese (IV) oxide producing solid zinc oxide and solid manganese (III) oxide.

Zn + 2 MnO₂ ⇒ ZnO + Mn₂O₃

This is a redox reaction. The Zn is being oxidized, and the Mn is being reduced.

Oxidation: Zn ⇒ Zn⁺² + 2 e⁻

Reduction: Mn⁺⁴ + e⁻ ⇒ Mn⁺³

Aqueous silver nitrate reacts with aqueous calcium chloride.

2 AgNO₃ + CaCl₂ ⇒ 2 AgCl + Ca(NO₃)₂

This is a precipitation reaction. You have two soluble salts combing to form a solution. You now need to figure out which of the compounds produced are not soluble. AgCl is the compound that is not soluble in water, making it the precipitate.

Calculate the concentration of H3O+ of a solution if the concentration of OH- at 25°C is 3.8 × 10-5 M and determine if the solut

sergejj [24]

Answer:

[H₃O⁺] = 2.63×10⁻¹⁰ M

As pH = 9.57, the solution is basic

Explanation:

We must know this knowledge:

[OH⁻] . [H₃O⁺] = 1×10⁻¹⁴

3.8×10⁻⁵ . [H₃O⁺] = 1×10⁻¹⁴

[H₃O⁺] = 1×10⁻¹⁴ / 3.8×10⁻⁵ → 2.63×10⁻¹⁰ M

Let's determine the pH to state if the solution is acidic or basic

pH < 7 → acidic ; pH > 7 → basi

pH = - log [H₃O⁺]

pH = - log 2.63×10⁻¹⁰ → 9.57
