Which phrase is an example of what electrostatic forces hold together?
Andreyy89

Answer:

Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together.

Explanation:

The interaction that occurs between atoms that have an electric charge is called electromagnetic force. When the charges are at rest, the interaction between them is called electrostatic force. This force depends on the distance "r" between the atoms.

Depending on the sign of the charges that interact, electrostatic force can be attractive or repulsive. The electrostatic interaction between charges of the same sign is repulsive (two negative charges or two positive charges), while the interaction between charges of the opposite sign (a negative charge and a positive charge) is attractive. In the case of neutral charges against negative or positive charges, no force is generated.

<u><em>Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together. </em></u>In this example you have a positively charged atom (Cs₊) and a negatively charged atom (Cl₋). As they are opposite charges they will attract.

<h3>Answer:</h3>

                    3.2 moles of Oxygen

<h3>Explanation:</h3>

                        Acetic Acid having chemical formula C₂H₄O₂ and structural formula attached below is the second member of carboxylic family in organic compounds. It is commonly used as vinegar<em> i.e</em>. a mixture containing 5 % Acetic acid and 95 % water.

As shown in structure 1 mole of Acetic acid contains 2 moles of Carbon atoms, 4 moles of Hydrogen atoms and 2 moles of Oxygen atoms respectively. Hence, the number of moles of Oxygen atoms contained by acetic acid containing 3.2 moles of Carbon is calculated as,

                      2 moles of C accompany  =  2 moles of O

So,

               3.2 moles of C will accompany  =  X moles of O

Solving for X,

                     X  =  (3.2 mol C × 2 mol O) ÷ 2 mol C

                      X =  3.2 mol of Oxygen
