Answer:
 = 61.25 g
 = 61.25 g
 = 88.75 g
 = 88.75 g
Explanation:
 =
 =  = 50 g
 = 50 g
⇒  =
 =  = 1.25 (moles)
 = 1.25 (moles)
2NaOH + H2SO4 ⇒ Na2SO4 + 2H2O 
    2        :     1           :      1         :    2
  1.25                                                       (moles) 
⇒   = 1.25 × 1 ÷ 2 = 0.625 (moles) ⇒
 = 1.25 × 1 ÷ 2 = 0.625 (moles) ⇒  = 0.625 × 98 = 61.25 g
 = 0.625 × 98 = 61.25 g
      = 1.25 × 1 ÷ 2 = 0.625 (moles) ⇒
 = 1.25 × 1 ÷ 2 = 0.625 (moles) ⇒ = 0.625 × 142 = 88.75 g
 = 0.625 × 142 = 88.75 g

<em>The number of protons and electrons in a neutral atom of the element are;</em>
D. 29 protons and 29 electrons 
<u>The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element.</u>
<u>Thus copper has an atomic number of 29, all atoms of copper will have 29 protons.</u>
