31,536,000 seconds because 365 days a year, 24 hours a day. Every hour is 60 minutes, and each minutes 60 seconds. So to get the answer 60 sec/min x 60 min/hr x 24 hr/day x 365 days/year = 31,536,000 seconds.
B. At-200
In beta decay the atomic number increases by 1
chemical equation
(a) NaOH +HCL --->NaCl +H2O
(b) THE number of moles reacted is = molarity x volume in litres
hence the number of moles of NaOH=(o.201 x 30.5ml)/100ml=0.00613 moles
(C) the number of moles of Hcl that were reacted, from the reaction above the recting ratio of NaOH to HCl is 1:1 thus the moles of HCl is also 0.00613
(D) my of HCl is =moles/volume in litres
that is (0.00613/20) x 1000=0.306M
Answer:
