Molecule of oxygen (O2) has a speed of 473 m/s at a certain temperature. Determine the speed of the molecule in kilometers per hour (km/h). Please show work.

You can use dimensional analysis to answer this question.

× × ×

= 1702.8 km/h

If you did this correctly, all your units should cancel out, leaving you with km/h

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
