I'm not sure how to draw it and show you, but I will type it out and hopefully you will understand.

4-nonene means the double bond is the fourth possible one:
CH 3 - CH 2 - CH 2 - CH=CH-CH 2 - CH 2 - CH 2 - CH 3
adding F2 means F2 are added across the double bond
-> CH 3 - CH 2 - CH 2 - CHF-CHF-CHF- CH 2 - CH 2 - CH 2 - CH 3
So: C9H18+F2 --> C9H18F2

Calcium chloride solution reacts with sodium carbonate solution

Klio2033 [76]

Reactions can occur because of a precipitation reaction

<h3>Further explanation</h3>

Double-Replacement reactions, happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

To predict whether this reaction can occur or not is one of them, the precipitation reaction. A precipitation reaction occurs if two ionic compounds which are dissolved reacted to produce one of the products of the ion compound does not dissolve. Formation of these precipitating compounds that cause reactions can occur

Chloride solution reacts with Sodium carbonate solution

CaCl₂(aq)+Na₂CO₃(aq)⇒CaCO₃(s)+NaCl(aq)

Because Calcium carbonate, CaCO₃ an insoluble solid , it will precipitates so that a reaction can occur

Hydrogen is diffusing through solid nickel. At a temperature of 358 K, the diffusivity is 1.16 x 10-8 cm2/s. At a temperature of

Lelu [443]

Answer:

Q_d=35881 J/mol

So the activation energy is 35881 J/mol.

Explanation:

Consider the following equations:

$lnD_{1} =lnD_{o} -\frac{Q_{d} }{R*T_{1} }$

$lnD_{2} =lnD_{o} -\frac{Q_{d} }{R*T_{2} }$

Solving the above two equation to find the Q_d in term of diffusivity and temperature we will get:

$Q_{d}=-R*\frac{lnD_{1} -lnD_{2} }{\frac{1}{T_{1} }-\frac{1}{T_{2} } }$

where:

Q_d is the activation energy

D_1 is the diffusivity at T_1

D_2 is the diffusivity at T_2

$Q_{d}=-8.31*\frac{ln1.16*10^-12 -ln1.05*10^-11 }{\frac{1}{358 }-\frac{1}{438 } }$

Q_d=35881 J/mol

So the activation energy is 35881 J/mol.

3. Suggest . how to do an experiment to find the solubility of salt

slamgirl [31]

You can put salt in water and record how long that takes the water to dissolve. And then have just water in a cup and see how long it takes the water ti dissolve compared to the salt water.

What is the density of HDPE vs Water?

Kamila [148]

Water has a density of around 1 g/mL. The density of HDPE varies depending on exact formulation and processing, but it typically is within the range of 0.93 to 0.97 g/mL. This means that HDPE is less dense compared to water.
