Example 1: Crushing a can.
Type of change:
Developmental – May be either planned or emergent; it is first order, or incremental. ...
Transitional – Seeks to achieve a known desired state that is different from the existing one. ...
Transformational – Is radical or second order in nature.
Nitric acid is a strong acid while the nitrate ion is a very weak base. Nitric acid is able to consume hydroxide ions. However, the nitrate ions present are unable to consume hydronium ions. As a result, the set of compounds does not form a buffer solution.

What Is Molar Mass?</h3>
A mole is the number of entities present in a substance, such as atoms, molecules, or ions. A mole of any substance is defined as 6.0221023 molecules. Just as we use a standard value to quantify diverse things, such as 1 dozen = 12 items, we utilise the mole to quantitatively calculate the size of the tiniest creatures.
The number of atoms in 12g (0.012 kg) of 12C isotope is equal to the number of particles in 1 mole of the substance. One of the most crucial facts to remember is that the mole of a material always includes the same number of entities regardless of the substance.

Lava that formed in these columns of Iceland is basaltic lava.
<h3>What is molten basaltic lava?</h3>
The Icelandic type causes the effusions of molten basaltic lava that flow from long, parallel fissures. Such outpourings produce lava plateaus. mountain type of mountains are formed due to such type of eruption of lava. The mountain was formed when the eruption occur under the ice sheet. Basaltic lava is another name of mafic lava. Mafic lava is molten rock that contain iron, magnesium and lower amount of silica. When mafic lava cools on the earth's surface, it produces basalt.
So we can conclude that Lava that formed in these columns of Iceland is basaltic lava.

I got 9.25527 for the pKa
<span>then for the Henderson-Hasselbalch equation: </span>
<span>9.00=9.25527+log(.600/acid) </span>
10^(-.25527)=(.600/acid)correct to this line. Then
0.5556 = 0.6/acid and
acid = 0.6/0.5556 = 1.08 which is the reciprocal of your number)
<span>.5556/.600M=acid </span>
<span>acid=.925925...M </span>
<span>(.925925)*2.10L= Molarity</span>
Answer:
Background
Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other. ...
Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded. ...
Gases – no definite volume or shape
