Answer:

C. The product must solve the problem for which it was designed.

Explanation:

Technological design is the study, development and application of technological process with the intent of designing a product to solve required problem.The process could be based on the use of a computer.

Generally, technological process and development always tend to design a problem solver product. Through this process, more new technologies are produced.

Therefore in technological process, the product must solve the problem for which it was designed.

Hydrogen bromide decomposes when heated to 437C according to the equation: 2HBr(g) H2(g) Br2(g). If the reaction starts with 2.1
iren [92.7K]

Answer:

<h3>the equilibrium constant of the decomposition of hydrogen bromide is 0.084</h3>

Explanation:

Amount of HBr dissociated

2.15 \ mole \times \frac{36.7}{100} \\\\=0.789 \ mole

                                  2HBr(g)        ⇆          H2(g)           +          Br2(g)

Initial Changes          2.15                             0                                0  (mol)

                                - 0.789                      + 0.395                     + 0.395 (mol)

At equilibrium        1.361                            0.395                         0.395 (mole)

Concentration        1.361 / 1                   0.395 / 1                      0.395 / 1

at equilibrium (mole/L)

K_c=\frac{[H_2][Br_2]}{[HBr]^2} \\\\=\frac{(0.395)(0.395)}{(1.361)^2} \\\\=\frac{0.156025}{1.852321} \\\\=0.084

<h3>Therefore, the equilibrium constant of the decomposition of hydrogen bromide is 0.084</h3>

Calculate the mole fraction of the total ions in an aqueous solution prepared by dissolving 0.400 moles of MgBr2 in 850.0 g of w
diamong [38]
 <span>moles water = 850.0 g / 18.02 g/mol=47.2 
moles Mg2+ = 0.400 
moles Cl- = 2 x 0.400 = 0.800 
moles ions = 0.400 + 0.800= 1.2 
mole fraction ions = 1.2 / 1.2 + 47.2 =0.0248</span>
