ing what you know about ions and acid/base reaction, find the formulas of the products (2pts). Assume double displacement. Then balance the equations below (2pts). (4 total each) 9. 4(ag) 11. (4pts) Find the blank: 12. What radiation has the best penetration? (3 pts) \'onZr +2 on+ 60-1e4 13. What radiation causes the most tissue damage? (3 pts) 14. A patient is exposed to 0.0453 Curie (Ci). How many Becquerel is that (Bq)? (3pts)
Solution
Ans 9 :
The reaction is called as neutralisation , or acid-base reaction , in which a salt is formed as the major product and water is formed as the byproduct.
So the complete balanced reaction along with the products is given as :
NaOH (aq) + HC2H3O2 (aq) = CH3COONa (aq) + H2O (l)
Ans 10 :
Even here Al(OH)3 is base and H2SO4 is an acid.
The balanced reaction and its products is given as :
2Al(OH)3 (aq) + 3H2SO4 (aq) = Al2(SO4)3 (aq) + 6H2O (l)
.
This PowerPoint helps students to consider the concept of infinity.
