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.
The volume of object is 3.2 ml
<h3>Explanation:</h3>
Given:
Mass of the object = M = 9.6 g
Initial volume of liquid:
Final volume of liquid after displacement:
Total volume of the displaced object inside a graduating cylinder will be given as difference between the final volume and initial volume of the expanding object.
V = 3.2 ml
1 mole ----------- 6.02x10²³ atoms
1.75 moles ------- ?
atoms = 1.75 * 6.02x10²³ / 1
= 1.053x10²⁴ atoms
hope this helps!
