Answer: According to the reactivity of metals Sodium is the second metal while Magneesium is the fourth metal. The metal in the top of the reactivity serise table are more reactive.
<em>(The series obtained by the arrangement of metals in the decending oder of their reactivity is the REACTIVITY SERIES TABLE)</em>
Explanation:
K
<u><em>Na</em></u>
Ca
<u><em>Mg</em></u>
Al
Zn
Fe
Sn
Pb
H
Cu
Hg
Ag
Pt
Au
Therefore Sodium is more reactive than Magnesium
Answer:
Water has 18 grams per mole so 9 grams is 0.5 moles of water. There are 6.022* 10^23 molecules in a mole. Each water molecule contains one oxygen and two hydrogens.
Remember velocity = distance/time so that mean you would do 60/3 which equals 20 so the speed(velocity) equals 20
