2. C2H6 + O2 ---> H2O + CO2
3. KOH + H3PO4 ---> K3PO4 + H2O
4. SnO2 + H2 ---> Sn + H2O
5. NH3 + O2 ---> NO + H2O
6. KNO3 + H2CO3 ---> K2CO3 + HNO3
7. B2Br6 + HNO3 ---> B(NO3)3 + HBr
8. BF3 + Li2SO3 ---> B2(SO3)3 + LiF
9. (NH4)3PO4 + Pb(NO3)4 ---> Pb3(PO4)4 + NH4NO3
10. SeCl6 + O2 ---> SeO2 + Cl2

we need the questions , i may then you.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
