Answer:
An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms.
Explanation:
It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions. One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world
Answer:
3 moles
Explanation:
3 moles atoms are needed to react with 50 grams of O2 gas.
Answer:
Image result for How do solute concentrations affect the rate of osmosis within the cell?
Concentration gradient - The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent.
I think this is it^^^
Explanation:
Answer is: below magnesium in group 2 or in group 1 (left from magnesium).
Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity).
This series are used to summarize information about the reactions of metals with acids or water, double displacement reactions (more reactive metals displace metals with lower reactivity) and the extraction of metals from their ores.
Sodium and potassium (group 1 - alkaline metal) are more reactive than magnesium.
Strontium and barium (group 2 in periodic table) are higher in this group from magnesium. Strontium is stronger reducing agent than magnesium, gives electrons easier.
