Answer:

<h2>Chemical equilibrium, however, is always the point at which there is no bias towards creating products or reactants. If the forward reaction rate and reverse reaction rate are equal, then there is no net change in concentration of the reactants or products. This makes them appear to be stable.</h2>

What is the volume of 68.0 g of ether if the density of ether is 0.72 g/mL?

umka2103 [35]

Answer:

94.44

Explanation:

Volume is equal to Mass/Density so therefore, you do the mass which is 68.0 g/0.72 g/mL which is the density and get 94.44 mL because the g cancel each other out when it comes to the label!

(a) what is the approximate ductility (%el) of a brass that has a yield strength of 230 mpa (33360 psi)?

ss7ja [257]

Based on the calculations, the approximate ductility (%el) of this brass is equal to 2.3%.

<u>Given the following data:</u>

Yield strength = 230 mpa (33360 psi).

<h3>What is ductility?</h3>

Ductility can be defined as an important property of a material which determines its ability to become elongated due to the application of stress.

Mathematically, the ductility of a material can be expressed as percentage elongation in length:

$\% el = \frac{\Delta L}{L_i} =\frac{L_f - L_i}{L_i}$

<u>Where:</u>

$L_i$ is the original length.

$L_f$ is the final length.

$\Delta L$ is the yield strength.

For this exercise, let us assume the original length of this brass is equal to 100 meters.

Substituting the parameters into the formula, we have;

$\% el = \frac{230}{100}$

Ductility = 2.3%.
