Consider the following intermediate chemical equations. 2 equations. First: C(s)+(1/2)O2(g) ---->CO(g). Second: CO(g)+(1/2)O2

(g) ---->CO2(g). How will oxygen appear in the final chemical equation?

Answer:

The oxygen will appear in the final stage if the oxygen is excess from the beginning.

Explanation:

1. C +(1/2)O2 —> CO

2. CO+(1/2)O2—> CO2

The first stage explains that the oxygen is limited and hence CO is produced.

The 2nd stage explains that if the oxygen is excess, then CO2 will be produced.

The overall reaction when oxygen is excess is given by:

C + O2 —> CO2

In the right triangle shown, m\angle V = 60\degreem∠V=60°m, angle, V, equals, 60, degree and UV= 18UV=18U, V, equals, 18.How lon
Natasha_Volkova [10]

Answer:

9√3

Explanation:

Given that :

UV = 18

Angle V = 60°

To obtain the measure of UW = v

Using trigonometry :

Sinθ = opposite / hypotenus

Sinθ = UW / 18

θ = 60°

sin60° = UW / 18

Sin 60° = √3/2

√3 /2 = UW / 18

UW = 18 * √3/2

UW = 9 * √3

UW = 9√3

when 0.863 mol acetone is dissolved in 500 g benzene, the freezing point of benzene drops 8.84°C. what is the molal freezing poi
sveticcg [70]

Answer:

  • <u>Kf = 5.12 °C/m</u>

Explanation:

<u>1) Data:</u>

a) Solute: acetone

b) Solvent: benzene

c) n (solute) = 0.863 mol

d) mass of solvent = 500 g = 0.500 Kg

e) ΔTf = 8.84 °C

f) Kf = ?

<u>2) Formulae:</u>

  • Depression of freezing point: ΔTf = m . Kf

  • Molality: m = n (solute) / kg solvent

<u>3) Solution:</u>

a) m = 0.863 mol / 0.500 kg = 1.726 m

b) Kf = ΔTf / m = 8.84°C / 1.726 m  = 5.12 °C/m ← answer

How many moles in 2 h2o molecules
alexandr1967 [171]

Answer:

2 molecules of water represents 3.32 x 10^-24 moles of water.

Explanation:

To find the solution to this problem, you have to use the concept of Avogadro´s number, that is in 1 mol of any element o compound there are                    6.022 x 10^23 molecules. Then,

1 mol H2O ------------- 6.022 x 10^23 molecules

x= 3.32 x 10^-24 ---- 2 molecules.

2 molecules of water represents 3.32 x 10^-24 moles of water.
