For electricity to flow there must be a flow of electrons or ions present in a system or medium. When electricity is passed in pure water, oxygen does not have d-orbitals or f-orbitals through which electrons may pass. In pure water there are no electrolytic substance, so no ions present in the pure water. Therefore electricity can not pass through pure water. Additionally; water cannot dissociate into OH- and H+ when electricity is passed through pure water.
Answer:
Nitrogen and Arsenic
Explanation:
Since Phosphorous and Arsenic both are Nitrogen group elements i.e. Group(Va)
Answer:
5.95g
Explanation:
1
= 1000 mL
∴ 100 mL = 100 ÷ 1000 = 0.1 
Volume = <u>0.1 </u>
<u />
Concentration = <u>0.5 M</u>
Concentration =
0.5 = 
No. of moles = 0.5 x 0.1 = <u>0.05 moles</u>
No. of moles =
Mass in 1 mole of KBr = 39 + 80 = 119g (39 is the mass of potassium and 80 is the mass of bromine)
0.05 = 
x = 119 × 0.05 = 5.95g
