Butadiene c4h6 reacts with itself at 250 degrees celcius to form a dimer with the formula c8h12. The reaction is second order in

goldfiish [28.3K]

Answer:

Rate = k * [C₄H₆]²

Explanation:

It is possible to write the reaction as:

2C₄H₆ → C₈H₁₂

The differential rate law for a simple second order reaction of the type 2A → B is:

Rate = k * [A]²

With the above information in mind, the rate law for the reaction of butadiene would be:

Rate = k * [C₄H₆]²

can someone help me with these? I just started chemistry this semester, and since it's involving math I don't see myself doing g

Any non zero digits are significant. (120 has 2 sig figs)

Zeroes between significant digits are significant. (103 has 3 sig figs)

Zeroes only count if there is a decimal point and if they are following a significant digit. (.600 has 3 sig figs; .067 has 2 sig figs)

1) 1278.50 = 6 sig figs

2) 120000 = 2 sig figs

3) 90027.00 = 7 sig figs

4) 0.0053567 = 5 sig figs

5) 670 = 2 sig figs

6) 0.00730 = 3 sig figs

That's all I'm gonna do so yeah.

Now for the rounding, it's basically rounding but it must have the x amount of sig figs after rounding. It's pretty hard to explain.

19, I'm not really sure. Might be 120 with a decimal point at the end.

20) 5.457, alright so here, since we are rounding to three significant digits, we look at the third sig fig. The third sig fig here would be 5. Then we just round. Since the number next to 5 is 7, we round 5 up to 6.

So 5.457 rounded to 3 sig figs would be 5.46

21) 0.0008769, the third sig fig here would be 6. You round 6 up to 7 because the number next to it is 9.

So 0.0008769 rounded to 3 sig figs would be 0.000877

So I hope you get it, I'm gonna let you do the rest.

1. Determine the number of significant figures in the following values:

denpristay [2]

Answer:

The zero to the left of a decimal value less than 1 is not significant.All trailing zeros that are placeholders are not significant.Zeros between non-zero numbers are significant.All non-zero numbers are significant.

There are several aromatic compounds with the formula c8h9cl. Draw those that have a monosubstituted ring.

anygoal [31]

Answer:

As shown in the attachment.

Explanation:

In this case, there are two isomers possible. Isomers are compounds that have the same molecular formular but different structural formular.

Considering the hydrocarbon C8H10, which has 8C expected saturated hydrocarbon. however when there is an excess of 8H, we have C8H18 which is the formular of octane, a member of the alkane family and from monosubstitution reaction which involves reaction with halogens (particularly Chlorine), the reaction will be a repeated substitution reaction where chlorine will be replaced with each of the hydrogen.
