How many Joules of heat are required to melt 250 grams of ice at 0°C?
AHfus = 334 J/g
AHvap = 2258 J/g
Cp= 4.184 J/g C

Answers

Answer:

cp =4.184/c / j

Explanation:

ahvap=2258j/g

Heat required : Q = 83500 J = 83.5 kJ

Further explanation

Given

mass ice = 250 g at 0°C

Required

The heat required

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Lf=latent heat of fusion

Input the value :

Q = 250 g x 334 J/g

Q = 83500 J

If 10.0 L of nitrogen gas reacts with 16.0 L of hydrogen gas, how many liters of ammonia gas (NH3) will be
produced?

Answers

Volume of ammonia gas : 10.67 L

Further explanation

Given

10.0 L of nitrogen gas

16.0 L of hydrogen gas

Required

Volume of ammonia gas

Solution

Reaction

N₂ + 3H₂ ⇒ 2NH₃

From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

Find limiting reactant :

N₂ : 10 : 1 = 10

H₂ : 16 : 3 = 5.3

H₂ as a limiting reactant

So volume of NH₃ based on H₂

= 2/3 x volume H₂

= 2/3 x 16 L

= 10.67 L

How many grams of NH3 can be dissolved in 50 grams of water at 50oC?

Answers

15 grams of  NH3 can be dissolved

Further explanation

Given

50 grams of water at 50°C

Required

mass of NH3

Solution

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility  

1. Temperature: 2. Surface area: 3. Solvent type: 4. Stirring process:

We can use solubility chart (attached) to determine the solubility of NH3 at 50°C

From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g

So that the solubility in 50 grams of water is:

= 50/100 x 30

= 15 grams

A chemical process used to produce ethanol as a fuel additive was expected to produce 5,000 kilograms of ethanol based on the amounts of starting materials used, but only 4,760 kilograms were produced. What was the percent yield for ethanol in this process?
A)1.09
B)4.80
C)95.2
D)105

Answers

Answer:

C)95.2

Explanation:

Given parameters:

Expected yield  = 5000kg

Experimental  yield  = 4760kg

Unknown:

Percentage yield  = ?

Solution:

The percentage yield of the substance is determined by find the ratio of the true experimental yield to the expect yield and multiply by 100;

  Percentage yield  = [tex]\frac{4760}{5000}[/tex] x 100 = 95.2%

A gas that exerts a pressure of
15.6 psi in a container with a volume of
L will exert a
pressure
of
25.43 psi when transferred to a
container with a volume of 1.895 L.

Answers

Answer:

V1 = 3.09 L

Explanation:

Initial Pressure, P1 = 15.6 psi

Initial Volume, V1 = ?

Final Pressure, P2 = 25.43 psi

Final Volume, V2 = 1.895 L

The relationship between these quantities is given by boyles law;

V1P1 = V2P2

V1 = V2P2 / P1 = 1.895 * 25.43 / 15.6

V1 = 3.09 L
