Does technology always follow science? Explain.
nalin [4]
Always is a pretty absolute word and since nothing is impossible I would say no. However, usually for the most part technology does follow science.
If you want to develop a technology, you need to understand the physical principals behind it such as dynamics,material behavior, etc. this all requires knowledge physics and chemistry.
<span>
Physicists during the 1800's were studying the theory to magnetic and electric fields and their interactions way before they were devices to create/observe this phenomenon esp. according to their theory.</span><span>

The elementary reaction 2H2O(g)↽−−⇀2H2(g)+O2(g) proceeds at a certain temperature until the partial pressures of H2O, H2, and O2
jenyasd209 [6]

Answer:

1.742\times 10^{-5} is the value of the equilibrium constant at this temperature.

Explanation:

2H_2O\rightleftharpoons 2H_2+O_2

We are given:

Partial pressure of H_2O=p^o_{H_2O}=0.0750 atm

Partial pressure of H_2=p^o_{H_2}=0.00700 atm

Partial pressure of O_2=p^o_{O_2}=0.00200 atm

The expression of K_p for the given chemical equation is:

K_p=\frac{p^o_{H_2}^2\times p^o_{O_2}}{p^o_{H_2O}^2}

Putting values in above equation, we get:

K_p=\frac{(0.00700 atm)^2\times 0.00200 atm}{(0.0750 atm)^2}\\\\K_p=1.742\times 10^{-5}

1.742\times 10^{-5} is the value of the equilibrium constant at this temperature.

Allicin contains 59.9 g of carbon, 21.7 g of hydrogen, 24.4 g of oxygen, and sulfur. What is the mass percent of sulfur in a 162
ruslelena [56]

Answer:

The molar mass of Allicin is 162 which means that you can just divide 64 by 162 since 64 is the mass of sulfur in 1 mole of Allicin (32×2=64). You should get 0.395 which is 39.5%
