The conductivity of a substance is the ability or power to conduct or transmit energy (in the form of heat, electricity, etc.) or waves (in the form of sound). It is measured in Siemens per meter.

What is a saturted solution

andrew-mc [135]

Answer:

Please find the definition and further explanation below

Explanation:

Based on the ability for the solvent (liquid substance) to dissolve a solute (solid substance), a solution can either be unsaturated, saturated or supersaturated. A SATURATED SOLUTION is that which contains the maximum amount of solute a solvent can possibly dissolve.

In other words, a saturated solution can no longer dissolve anymore solute, and hence, any further solute added forms crystals or makes the solution supersaturated.

For the reaction, 2A + B → 3C, rate of disappearance of A is 0.3 M/s in a certain time interval.What is the average rate of appe

andrezito [222]

Answer:

E) rate of appearance of C = 0.45 M/s

rate of the reaction = 0.15 M/s

Explanation:

2A + B → 3C

Writing rate law for the reaction:

<u>Rate of reaction</u> = - $\frac{1}{2}$ $\frac{d[A]}{dt}$ = - $\frac{d[B]}{dt}$ = $\frac{1}{3}$ $\frac{d[C]}{dt}$ → equation 1

Given that the rate of disappearance of A is 0.3 M/s

⇒ - $\frac{d[A]}{dt}$ = 0.3 M/s

⇒Rate of reaction = - $\frac{1}{2}$ $\frac{d[A]}{dt}$ = $\frac{1}{2}$ ×0.3 M/s

⇒<u>Rate of reaction = 0.15 M/s</u>

From equation 1, $\frac{d[C]}{dt}$ = - $\frac{3}{2}$ $\frac{d[A]}{dt}$ = $\frac{3}{2}$ ×0.3 M/s

⇒ $\frac{d[C]}{dt}$ = 0.45 M/s

or <u>the rate of appearance of C = 0.45 M/s</u>

In this reaction, a gaseous system with a volume of 3.00 L has a rate of formation of NOCl of 0.0120 M s-1 . The volume of the s

oee [108]

Answer:

x = 0.324 M s⁻¹

Explanation:

Equation for the reaction can be represented as:

2 NO(g) + Cl₂ (g) ⇄ 2NOCl (g)

Rate = K [NO]² [Cl₂]

Concentration = $\frac{numbers of mole (n)}{volume (v)}$

from the question; their number of moles are constant since the species are quite alike.

As such; if Concentration varies inversely proportional to the volume;

we have: Concentration ∝ $\frac{1}{v}$

Concentration = $\frac{1}{v}$

Similarly; the Rate can now be expressed as:

Rate = K [NO]² [Cl₂]

Rate = $(\frac{1}{v}) ^2$ $(\frac{1}{v} )$

Rate = $\frac{1}{v^3}$

We were also told that the in the reaction, the gaseous system has an initial volume of 3.00 L and rate of formation of 0.0120 Ms⁻¹

So we can have:

0.0120 = $\frac{1}{3^3}$

0.0120 = $\frac{1}{27}$ -----Equation (1)

Now; the new rate of formation when the volume of the system decreased to 1.00 L can now be calculated as:

x = $(\frac{1}{1})^3$

x = 1 ------- Equation (2)

Dividing equation (2) with equation (1); we have:

$\frac{0.0210}{x}$ = $\frac{\frac{1}{27} }{1}$

$\frac{0.0210}{x}$ = $\frac{1}{27}$

x = 0.0120 × 27

x = 0.324 M s⁻¹

∴ the new rate of formation of NOCl = 0.324 M s⁻¹

Does the attractive forces between the bonded atoms become weaker or stronger when a chemical bond breaks?

kicyunya [14]

The more electrons that are shared between two atoms, the stronger their bond will be. Covalent bonding is an example.
