Termination

Additionally, curved arrows serve as a method of tracking changes in formal charge. Another technique to track changes in formal charge is with curved arrows: The atom at the tail will formally "lose" one electron because a pair of electrons are being given from it, increasing its charge by one.

<h3>What is radical mechanism ?</h3>

Three steps—initiation, propagation, and termination—define the radical chain mechanism. Energy must be provided for reaction to start, but once it does, it continues on its own.

A free radical is referred to be a chemical entity that can exist independently and have an unpaired electron in its atomic orbital. The unpaired electron confers some common characteristics on all radicals.

You only have 15g of sodium to use for this reaction. how much copper(ii must you combine with the sodium to isolate the maximum

Eva8 [605]

The balanced chemical reaction is:

<span>CuCl2 + 2Na → 2NaCl + Cu

We are given the amount of sodium to be used up in the reaction. This will be the starting point for our calculations.

15 g Na ( 1 mol / 22.99 ) ( 1 mol Cul2 / 2 mol Na ) (134.45 g / 1 mol ) = 43.86 g CuCl2 needed to be able to obtain the maximum amount of copper.</span>

Hydrogen iodide can decompose into hydrogen and iodine gases. 2 HI(g) H2(g) + 12(g) Kp for the reaction is 0.016. If 0.350 atm o

solniwko [45]

Answer : The total pressure at equilibrium is 0.350 atm

Solution : Given,

Initial pressure of $HI$ = 0.350 bar

$K_p$ = 0.016

The given equilibrium reaction is,

$2HI(g)\rightleftharpoons H_2(g)+I_2(g)$

Initially 0.350 0 0

At equilibrium (0.350-2x) x x

The total pressure at equilibrium = $(0.350-2x)+x+x=0.350-2x+2x=0.350atm$

Thus, the total pressure at equilibrium is 0.350 atm

A glass laboratory flask is filled with gas at 24 ∘C and 0.95 atm pressure, sealed, and then heated to 104 ∘C. What is the press

Elan Coil [88]

The pressure inside the flask on heating it is given as 1.21 atm.

<u>Explanation:</u>

As per Guy Lussac's law, the pressure of any concealed volume of gas particles will be directly proportional to the temperature of the container of the gas particles.

So P ∝ T

To convert celsius to kelvin, add 273.15 to the temperature value in celsius

Since, here the initial temperature of the flask is given as 24°C, so in kelvin it will be 297.15 K. Similarly, the final temperature is said to be 104°C which will be equal to 377.15 K. Then the final pressure will be increased as there is increase in temperature. So, the final pressure inside the flask can be obtained as

$\frac{P_{1} }{T_{1} } = \frac{P_{2} }{T_{2} }$

$P_{2} = \frac{P_{1} }{T_{1} } \times T_{2} =\frac{0.95}{297.15} \times 377.15 =1.21\ atm$

So, the pressure inside the flask on heating it is given as 1.21 atm.

Silicon has some properties of metal and some properties of non metals silicon is used on solar panels.

Oksi-84 [34.3K]

Based on the above descriptions provided for silicon, I'm assuming that you want to know what silicon is categorized as, in the periodic table, since it posses some properties of metals and nonmetals it would be classified as a mettaloid or a semi metal.
