The metric prefix name for 1/100 is centimeters.
Answer: Ca(OH)2 (aq) + H2SO4 (aq) ----------> CaSO4(aq) + 2H2O(l)
Explanation:
Since this is a neutralization reaction, the end product would be salt and water. In this equation Calcium will displace hydrogen from the acid because it is more reactive, resulting in the formation of CaSO4 (salt), while the displaced H2 molecule combines with OH molecules to form water.
The equation of the reaction is thus;
Ca(OH)2 (aq) + H2SO4 (aq) ----------> CaSO4(aq) + H2O(l), in other to balance it, we add ''2'' to the water molecule in the right hand side of the equation.
Balance equation is
Ca(OH)2 (aq) + H2SO4 (aq) ----------> CaSO4(aq) + 2H2O(l)
Answer:
Total cost = $40.25 (Approx)
Explanation:
Given:
Per ounce = $1.15
Number of student = 28
Each student eat = 0.035 kg
Find:
Total cost
Computation:
Total weight of candy = 28 × 0.035 kg
Total weight of candy = 0.98 kg
1 ounce = 0.028 kg (approx).
Total weight of candy = 0.98 kg / 0.028
Total weight of candy = 35 ounce (Approx)
Total cost = 35 × $1.15
Total cost = $40.25 (Approx)
Yes, S-blocks are metals except for helium and hydrogen. The S-block metals are shiny, silvery and relatively soft, although they can easily lose electrons. Helium and hydrogen have valence electrons but also lack some similar properties as the other metals.
