Adhesion is the attraction of molecules of one kind for molecules of a different kind... water is adhesive because the water molecules are attracted to the straw and therefore adhere to it. Thus, adhesive forces are important for sustaining life. This is because of these forces, water can flow up from the roots to the tops of plants to feed the plant, allowing it to move against gravity through plant cells. Another example of why its important that water is adhesive is the movement of water to the tops of trees and the drainage of tears from tear ducts in the corners of your eyes. Or how water droplets stick to the end of the pine needles. These are all examples of adhesion.

Balance of Atoms Quick Check

san4es73 [151]

When iron rusts and forms iron oxide, the iron oxide has more mass than the iron because there are more iron atoms in iron oxide than in pure iron.

The process of rust occurs when pure iron is exposed to air and moisture. Rust is the oxidation of pure iron to iron II oxide (Fe2O3).

We can see that there are two iron atoms per mole of Fe2O3 whereas there is only one iron atom in each mole of pure iron.

Therefore, iron oxide has more mass than the iron because there are more iron atoms in iron oxide than in pure iron.

What would happen to the rate of a reaction with rate law rate = k [NO]^2[H2] if

Ede4ka [16]

The rate of a reaction would be one-fourth.

<h3>Further explanation</h3>

Given

Rate law-r₁ = k [NO]²[H2]

Required

The rate of a reaction

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.

Can be formulated:

Reaction: aA ---> bB

$\large{\boxed{\boxed{\bold{v~=~-\frac{\Delta A}{\Delta t}}}}$

$\large{\boxed{\boxed{\bold{v~=~+\frac{\Delta B}{\Delta t}}}}$

The concentration of NO were halved, so the rate :

$\tt r_2=k[\dfrac{1}{2}No]^2[H_2]\\\\r_2=\dfrac{1}{4}k.[No]^2[H_2]\\\\r_2=\dfrac{1}{4}r_1$
