<u>3. Sulfuric acid</u>
<u>4. Potassium hydroxide</u>
Answer: 2
Explanation: Potassium, K, has only 1 valence electron, 4s^1. Oxygen, O, needs 2 more electrons to complete its valence shell to make 8 electrons. That means 2 K atoms will combine with 1 O atom, to produce K2O, potassium oxide. Both K electrons are stolen by the single O atom, so 2 electrons are transferred.
Greater than, I believe. 5x10 = 50. -4 is the opposite of +4 and 1.0 is just like the positive number one.
Answer:
<u><em>TRUE</em></u> ,hope it helped you
Explanation:
The activity series goes top to bottom, most active to least active elements, going: Li, K, Ba, Sr, Ca, Na, Mg, Mn, Zn, Fe, Cd, Co, Ni, Sn, Pb, H, Cu, Ag, Hg, Au.
Thus, your list of metals would go from most reactive to least reactive: Li, K, Mg, Zn, Fe, Cu, Au
