Answer:
The rate of appearance of hydrogen gas is 0.095 M/s.
Explanation:
Rate of the reaction is the change in concentration of of any one of the reactants or products per unit time.
Given:
The rate of disappearance of HBr = ![-\frac{d[HBr]}{dt}=0.190 M/s](https://tex.z-dn.net/?f=-%5Cfrac%7Bd%5BHBr%5D%7D%7Bdt%7D%3D0.190%20M%2Fs)
Rate of the reaction is given by:
![R=-\frac{1}{2}\frac{d[HBr]}{dt}=\frac{1}{1}\frac{d[H_2]}{dt}](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7Bd%5BHBr%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D)
![R=-\frac{1}{2}\frac{d[HBr]}{dt}=\frac{1}{2}\times 0.190 M/s=0.095 M/s](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7Bd%5BHBr%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%200.190%20M%2Fs%3D0.095%20M%2Fs)
Rate of appearance of the hydrogen gas:
![\frac{d[H_2]}{dt}=R =0.095 M/s](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D%3DR%20%3D0.095%20M%2Fs)
The rate of appearance of hydrogen gas is 0.095 M/s.
I'm not sure but I think is C or D.
Answer:
petroleum, a fossil fuel, is extracted from the earth and mechanically transformed into fibers for clothing.
Explanation:
synthetic materials, like polyester, nylon and acrylic, don't exist naturally but are made in factories. Synthetics are created through an industrial manufacturing process in which
Answer: The force of attraction present between the solids depends on the type of solid.
Explanation:
For e.g. if solid is ionic solid, then the ionic forces hold on the solid molecules. And these forces hold together and form solid. When it comes to hydrogen bonding stronger the hydrogen bonding, more together the molecules and it become solid.
