Answer:

Explanation:

1. Force between two charged ions: Electrical force

Electrical force of attraction exists between two charged ions due to constant flow of electrons occuring within their field of influence.

2. Ion made of two or more atoms of  different elements : Polyatomic ion

A polyatomic ion is made up of two or more different elements. Most radicals forms polyatomic ion e.g SO₄²⁻

3. Compound whose atoms form bonds  by transferring electrons : Ionic compound

Ionic compounds forms by the transfer of electrons from a less electronegativbe atom to a more electronegative one. This is in a bid for the atoms to achieve stability.

4. Smooth solid formed by repeating  patterns of ions, atoms, or molecules

: Crystal

A crystal is a unit of an atom which is made up of definite repeating patterns over a long range.

5. Chemical bond formed when electrons  are transferred: Ionic bonds

The bonds resulting from the transfer of electrons between two atoms is an ionic bond. An example is that between Na⁺ ions and Cl⁻ ioin in NaCl

Answer:  At some point in your chemistry education, you may have been introduced to the song “The Elements in which Tom Lehrer does a rapid

fire musical rendition of all the elements' names. Like me, you may even have been offered the opportunity to memorize this song for extra credit. If so, it’s possible that you still remember the names of all the elements, which is an impressive feat—not to mention a fun trick to pull out at parties.

what is the percent yield of NaCl if 31.0 g of CuCl reacts with excess NaNo3 to produce 21.2 g of NaCl
olchik [2.2K]
Percentage Yield = (Actual Yield ÷ Theoretical Yield) × 100  

The Actual Yield is given in the question as 21.2 g of NaCl.  However, in order to find the theoretical yield, you have to write a balanced equation and use the mole ratio to calculate the mass of NaCl that would be produced.

Balanced Equation:   CuCl + NaNO₃    →    NaCl + CuNO₃

Moles of CuCl = Mass of CuCl ÷ Molar Mass of CuCl
                         =  31.0 g ÷ (63.5 + 35.5)g/mol
                         = 0.31 mol

the mole ratio of CuCl to NaCl is 1  :  1,
∴ if moles of CuCl = 0.31  mol,

then moles of NaCl = 0.31 mol

Now, Mass of NaCl = Moles of NaCl × Molar Mass of NaCl
                                 =  0.31 mol × (23 + 35.5) g/mol
                                 =  18.32 g

⇒ the THEORETICAL Yield of NaCl, in this case, is 18.32 g.

Now, since Percentage Yield = (Actual Yield ÷ Theoretical Yield) × 100  

⇒ Percentage Yield of NaCl = (21.2g ÷ 18.32g) × 100  
                                                = 115.7 %


NOTE: Typically, the percentage yield of a reaction is less than 100%, however in a case where the mass of the substance is weighed with impurities, then that mass may be in excess of 100% as seen here.

If the actual yielsd of a reaction is 50 g and the theoretical yield is 60 g. What is the percent yield.
balandron [24]
M₁=50 g
m₀=60 g

w=100m₁/m₀

w=100*50/60=83.3%
