Answer : The name of ionic compound is, Copper(II) fluoride.
Explanation :
Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.
Ionic compound are usually formed when a metal reacts with a non-metal.
The nomenclature of ionic compounds is given by:
1. Positive ion is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
3. In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.
is an ionic compound because copper element is a metal and fluorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The oxidation state of copper in
is, (+2)
Thus, the name of ionic compound is, Copper(II) fluoride.
Molarity = 3.9 * 10 ^ -8
pH = - log (3.9 * 10 ^ -8)
pH = - (-7.40893539)
pH = 7.409 = 7.4 ... Ans
Answer:
18 moles of H₂.
Explanation:
The balanced equation for the reaction is given below:
2Al + 6HCl –> 2AlCl₃ + 3H₂
From the balanced equation above,
2 moles of Al reacted to produce 3 moles of H₂.
Finally, we shall determine the number of mole of H₂ produced by the reaction of 12 moles of Al. This can be obtained as follow:
From the balanced equation above,
2 moles of Al reacted to produce 3 moles of H₂.
Therefore, 12 moles of Al will react to produce = (12 × 3)/2 = 18 moles of H₂.
Thus, 18 moles of H₂ were obtained from the reaction.
