An unknown substance has more OH- ions than tears but less OH- ions than ammonia. What is its approximate pH

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

not too sure thinking all accelerations are pointed down

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
