Calculate how much of the 0,005mol/dm3 of KMnO4 solution is needed to make four 50cm3 solutions with the following concentration 0,0001;0,0003;0,0006;0,0008 mol/dm3

how to make a simple air condition

2b2t

explanation:

2b2t

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
