What part of an atom bonds with other atoms
mote1985 [20]
Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another.

Calculate the mass of nickel metal which will react with 25mL of 0.15mol/L (
Fittoniya [83]

Answer:

0.110625 g of Ni

Explanation:

The first step in solving this problem is to put down the accurate chemical reaction equation.

Ni(s) + 2HCl(aq) ---> NiCl2(aq) + H2(g)

Secondly, we obtain the amount of HCl that reacted from the information provided.

Volume of HCl (V)= 25 ml

Concentration of HCl (C)= 0.15 mol/L

Then, to find the number of moles of HCl (n);

n= CV

Substitution values

n= 25/1000 × 0.15

n= 3.75 ×10^-3 moles

Mass of 3.75 ×10^-3 moles of HCl = number of moles × molar mass

Molar mass of HCl= 36.5 gmol-1

Therefore;

Mass of HCl = 3.75 ×10^-3 moles × 36.5 gmol-1

Mass of HCl= 0.136875 g of HCl

Thirdly we determine the mass of Ni reacted;

If 1 mole of Ni reacted with 2 moles of HCl according to the reaction equation

Then x moles of Ni reacts with 3.75 ×10^-3 moles of HCl

x= 1 × 3.75 ×10^-3 moles/ 2

x= 1.875 × 10^-3 moles of Ni

Mass of Ni= 1.875 × 10^-3 moles of Ni × 59 gmol-1

Mass of Ni= 0.110625 g of Ni

A reaction was performed in which 4.0 g of cyclohexanol was reacted with an acid catalyst to obtain 2.8 g of cyclohexene. calcul
ioda

Answer:

              %age Yield  =  85.36 %

Solution:

The Balance Chemical Reaction is as follow,

               C₆H₁₂O  +   Acid Catalyst    →    C₆H₁₀  +  Acid Catalyst + H₂O

According to Equation ,

              100 g (1 mole) C₆H₁₂O produces  =  82 g (1 moles) of C₆H₁₀

So,

                       4.0 g of C₆H₁₂O will produce  =  X g of C₆H₁₀

Solving for X,

                      X =  (4.0 g × 82 g) ÷ 100 g

                      X  =  3.28 g of C₆H₁₀   (Theoretical Yield)

As we know,

                     %age Yield  =  (Actual Yield ÷ Theoretical Yield) × 100

                     %age Yield  =  (2.8 g ÷ 3.28 g) × 100

                     %age Yield  =  85.36 %
