Heat produced =  -13588.956 kJ

<h3>Further explanation</h3>

Given

The reaction of combustion of Methane

CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔH∘rxn=−802.3kJ

271 g of CH4

Required

Heat produced

Solution

mol of 271 g CH₄ (MW=16 g/mol0

mol = mass : MW

mol = 271 : 16

mol = 16.9375

So Heat produced :

= mol x ΔH°rxn

= 16.9375 mol x −802.3kJ/mol = -13588.956 kJ

I need help completing this table regarding standard solution.
kramer

Answer:

The answer to your question is below

Explanation:

Data

Stock solution concentration = 0.00190 M

Volume stock solution = 10 ml

Final volume = 100 ml

Standard solution concentration = ?

Absorbance of the standard solution = 0.62

Process

A) 0.00190 M it was given in the data

B) 0.62            it was given in the data

C)                  C1V1  =  C2V2

                     C2 = C1V1/V2

                     C2 = (0.00190)(10)/100

                     C2 = 0.000190 M

D)   Ratio = Absorbance/Concentration = 0.62/0.000190

                                                                = 3263.2

How many gallons of a 60​% antifreeze solution must be mixed with 70 gallons of 25​% antifreeze to get a mixture that is 50​% ​a
Neporo4naja [7]

Answer:

The answer to your question is 175 gallons

Explanation:

Data

60% antifreeze solution  volume = ? = x

25% antifreeze solution   volume = 25%

Final concentration 50%

Process

              0.6x + 0.25(70) = 0.5(70 + x)

Simplification

              0.6x + 17.5 = 35 + 0.5x

              0.6x - 0.5x = 35 - 17.5

                          0.1x = 17.5

                              x = 17.5/0.1

Result

                              x = 175 gallons
