What is collision theory

2 answers:

8 0

The collision theory<span> explains that gas-phase chemical reactions occur when molecules </span>collide<span> with sufficient kinetic energy. The </span>collision theory<span> is based on the kinetic </span>theory<span> of gases; therefore only dealing with gas-phase chemical reactions are dealt with.

Hope this helps!</span>

Molecules must<span> collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules </span>must<span> collide with the proper orientation but the likely hood of this is really rare.</span>

A piston contains 0.39L of air at 1.0 atm. If the pressure on the piston is increased to 5.6 atm, what is the new volume?

bazaltina [42]

The new volume : 0.07 L

<h3>Further explanation</h3>

Boyle's Law

At a constant temperature, the gas volume is inversely proportional to the pressure applied

$\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}$

P₁=1 atm

V₁=0.39 L

P₂=5.6 atm

$\tt V_2=\dfrac{P_1.V_1}{P_2}\\\\V_2=\dfrac{1\times 0.39}{5.6}\\\\v_2=\boxed{\bold{0.07~L}}$

Solution X is a strong base with a pH of 12. Solution X is mixed with solution Y,and the pH of the resulting mixture is 8.Based

myrzilka [38]

The strong Base with a pH of 12 is reduced by 4 units upon being added with solution Y. If you added a strong acid to the strong base, all ions are present in the solution, yes? So every OH- is neutralised by every H+ for example, meaning the resultant pH should be 7. The resultant pH is only 8 however, so solution Y must be a <em>weak acid </em>only!

What is the product if an atom of Po-209<br> undergoes alpha decay?

g100num [7]

<h3>Answer:</h3>

Lead-205 (Pb-205)

<h3>Explanation:</h3>

<u>We are given;</u>

An atom of Po-209

We are supposed to identify its product after an alpha decay;

Polonium-209 has a mass number of 209 and an atomic number of 84.
When an element undergoes an alpha decay, the mass number decreases by 4 while the atomic number decreases by 2.
Therefore, when Po-209 undergoes alpha decay it results to the formation of a product with a mass number of 205 and atomic number of 82.
The product from this decay is Pb-205, because Pb-205 has a mass number of 205 and atomic number 82.

The equation for the decay is;

²⁰⁹₈₄Po → ²⁰⁵₈₂Pb + ⁴₂He

Note; An alpha particle is represented by a helium nucleus, ⁴₂He.
