It is a part of science because it was an invention that was made and inventions are because of science and it’s a technology because it is electrical
Answer:
Hailey should add, they are inexpensive to produce.
Explanation:
Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.
Reason being why the others are wrong, synthetic polymers are <u>not</u> biodegradable as they are made in a factory with oils. Synthetic polymers are <u>not</u> flexible due to them being used for harder products. Synthetic polymers are <u>not</u> recycled cheaply as they are made with chemicals which makes it very hard to recycle.
Answer:
0.146 M
Explanation:
Equation for the reaction :
2A(aq) ↔ B(aq) + C(aq)
= 65
Molar concentration of A = ![\frac{2.50 mol}{1.00 L}](https://tex.z-dn.net/?f=%5Cfrac%7B2.50%20mol%7D%7B1.00%20L%7D)
= 2.5 M
2A(aq) ↔ B(aq) + C(aq)
Initial 2.50 0 0
Change - 2x + x + x
Equilibrium 2.50 - 2x +x +x
![K_c =\frac {[B][C]}{[A]^2}](https://tex.z-dn.net/?f=K_c%20%3D%5Cfrac%20%7B%5BB%5D%5BC%5D%7D%7B%5BA%5D%5E2%7D)
![65 = \frac{[x][x]}{[2.5-2x]^2}](https://tex.z-dn.net/?f=65%20%3D%20%5Cfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B2.5-2x%5D%5E2%7D)
![65 = \frac{[x]^2}{[2.5-2x]^2}](https://tex.z-dn.net/?f=65%20%3D%20%5Cfrac%7B%5Bx%5D%5E2%7D%7B%5B2.5-2x%5D%5E2%7D)
![65 = (\frac{[x]}{[2.5-2x]})^2](https://tex.z-dn.net/?f=65%20%3D%20%28%5Cfrac%7B%5Bx%5D%7D%7B%5B2.5-2x%5D%7D%29%5E2)
![\sqrt 65 = \sqrt {(\frac{[x]}{[2.5-2x]})^2}](https://tex.z-dn.net/?f=%5Csqrt%2065%20%3D%20%20%5Csqrt%20%7B%28%5Cfrac%7B%5Bx%5D%7D%7B%5B2.5-2x%5D%7D%29%5E2%7D)
![8.062 = \frac{x}{2.5-2x}](https://tex.z-dn.net/?f=8.062%20%3D%20%20%5Cfrac%7Bx%7D%7B2.5-2x%7D)
8.062(2.5 - 2x) = x
20.155 - 16.124x = x
20.155 = 16.124x+x
20.155 = 17.124x
x = ![\frac{20.155}{17.124}](https://tex.z-dn.net/?f=%5Cfrac%7B20.155%7D%7B17.124%7D)
x = 1.177
[A] = 2.5 - 2x
= 2.5 - 2(1.177)
= 0.146 M
Therefore, the equilibrium concentration of A = 0.146 M
