Click the button within the activity, and analyze the relationship between the two reactions that are displayed. The reaction th

at was on the screen when you started and its derivative demonstrate that the change in enthalpy for a reaction, ΔH, is an extensive property. Using this property, calculate the change in enthalpy for Reaction 2. Reaction 1: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g), ΔH1=â’2043 kJ Reaction 2: 6C3H8(g)+30O2(g)→18CO2(g)+24H2O(g), ΔH2=?

Answer:

-12 258 kJ  

Step-by-step explanation:

Reaction 1: C₃H₈(g)+5O2(g) ⟶ 3CO₂(g)+ 4H₂O(g);          ΔH₁  = - 2 043 kJ  

Reaction 2: 6C₃H₈(g)+30O2(g) ⟶ 18CO₂(g)+ 24H₂O(g); ΔH₂ = -12 258 kJ

Reaction 2 is Reaction 1 multiplied by 6.

ΔH is an extensive property, so you must also <em>multiply ΔH by 6</em>.

2) Nitrogen gas will react with hydrogen gas to produce ammonia, NH3, How many
Delicious77 [7]

Answer:

12 grams of hydrogen gas

and 56 grams of nitrogen gas

The molar mass of ammonia is 17 g/mol.

68 grams of ammonia corresponds to  

17g/mol

68g

​

=4moles

4 moles of ammonia will be obtained from  

2

4×1

​

=2  moles of nitrogen and  

2

4×3

​

=6  moles of hydrogen.

The molar masses of nitrogen and hydrogen are 28 g/mol and 2 g/mol respectively.

2 moles of nitrogen corresponds to 2×28=56  grams.

6 moles of hydrogen corresponds to 6×2=12  grams.

What is the difference between viruses and bacteria? Write complete sentences?
andrew-mc [135]

Answer:

While both can cause disease, viruses are not living organisms, whereas bacteria are. Viruses are only "active" within host cells which they need to reproduce, while bacteria are single-celled organisms that produce their own energy and can reproduce on their own. Bacteria serve many vital roles in nature outside of being infectious.

Explanation:

Hope this helped! :)

A less-intense wave will have fewer _____ than a more-intense wave.
Shalnov [3]
A less intense wave will have fewer OSCILLATING AMPLITUDE than a more intense wave.
The intensity of a wave is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. Intense sounds are characterized by the particles of the medium vibrating back and forth with large amplitude.<span />
