The scientists research project with the goal of determining the sequence of chemical base pairs which make up human DNA, and of identifying and mapping<span> all of the genes of </span>the human genome<span> </span>
Acid + base ------> salt + water
Answer is: Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously.
For example, nitrogen molecules have weakest intermolecular bonds in gas phase and move fast and without order.
Cooling is change from liquids to solids. In solid state (for example ice) movement of molecules is more slow than movement of molecules in liquids (for example water).
In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object (for example iron) does not take on the shape of its container.
Liquids have definite volume, but no fixed shape.
Gases (for example nitrogen and neon) not have definite volume and fixed shape, it depends on its container.
<span> It is a type of potential </span>energy<span> that can be defined in two ways. In one way, the </span>lattice energy<span> is the </span>energy<span> required to break apart an ionic solid and convert its component atoms into gaseous ions</span>
<span>pH scale is used to determine how acidic, basic or neutral a solution is.
pH can be calculated using the Hydrogen ion concentration.
pH is calculated using the following formula
pH = -log [H</span>⁺<span>]
[H</span>⁺<span>] can be calculated knowing the pH
[H</span>⁺<span>] = antilog(-pH)
[H</span>⁺<span>] = 1.32 x 10</span>⁻¹⁰<span> M</span>
