A reaction occurs via the following sequence of elementary steps. What is the reaction intermediate?
Trava [24]

Answer:

C is the reaction intermediate.

Explanation:

A reaction intermediate is a molecular structure that is formed during the reaction but then is converted in the final products.

Usually, these reaction intermediates are unestable and, for that reason, the lifetime of these structures is low.

In the reaction, you can see in the first step C is produced, but also, in the second step reacts producing D. As is produced and, immediately consumed,

Please help ASAP thank you!!!!!
natali 33 [55]

Answer:

The new volume is 66.3 mL

Explanation:

Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2

P1 = 0.428 atm

P2=1.55 atm

V1 = 240 mL

V2 = ??

(0.428)(240)=(1.55)(V2)

102.72 = 1.55x

x = 102.72/1.55 = 66.27 mL.

¿Qué volumen ocuparán 12 g de hierro?
sasho [114]

Answer:

        \large\boxed{\large\boxed{volume=1.5cm^3}}

Explanation:

Translation:

  • <em>What volume will 12g of iron occupy?</em>

<em></em>

<h2>Solution</h2>

<em />

<em>Iron</em> is a solid substance at room temperature. You can find the <em>volume</em> of solids (and of not solids) using the density.

      Density=\dfrac{mass}{volume}

You can obtaindthe density of most pure substances in the internet. The density of<em> iron</em> at room temperature is 7.874 g/cm³.

Thus, substituting in the formula, you get:

      7.874g/cm^3=\dfrac{12g}{volume}\\ \\ \\ volume=\dfrac{12g}{7.874g/cm^3}\\ \\ \\ volume=1.5cm^3

The answer is rounded to two significant figures because the input, 12g, has two significant figures.
