Their formation involves rapid cooling
Answer:
4.68x10⁻⁵N
Explanation:
The pH is defined as -log [H⁺]. If an acid has a pH of 4.33, [H⁺] is:
pH = -log [H⁺]
4.33 = -log [H⁺]
10^(-4.33) = [H⁺]
4.68x10⁻⁵M = [H⁺]
The [H⁺] is in molarity units, that is mole / L. Normality has as units equivalent / L. As the equivalent in an acid-base reaction is defined as the number of moles of H⁺, in this case:
4.68x10⁻⁵M = <em>4.68x10⁻⁵N</em>
Answer:
Stroking a magnet across it or high voltage
Explanation:
Stroking a magnet across it causes the alignment of the domain, making it magnetic temporarily. Also, high voltages from batteries can make it magnetic too, doing the same thing.
Answer:
Step 1: Obtain the mass of each element present in grams. Element % = mass in g = m.
Step 2: Determine the number of moles of each type of atom present. ...
Step 3: Divide the number of moles of each element by the smallest number of moles. ...
Step 4: Convert numbers to whole numbers.

Answer:
Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, The Sceptical Chymist is seen as a cornerstone book in the field of chemistry.
