Group 1A Metal with Water
What results from the reaction between lithium and water?
Determine the reactants and the type of metal,
We will first read the issue and determine the reactants. As we can see, the reactants are lithium and water, which are represented by the letters Li and H_2O. Li is found in the first column and second row of the periodic table, as can be seen by looking at it. So, Li is a Group 1A metal.
Li may now be entered into the generic group 1A reaction equation.
2Li(s)+2H2O->2LiOH(aq)+H_2(g)
Water and lithium and other alkali metals react violently, oxidizing the metal to its ionic form of Li+ and reducing the water to hydroxide ions, OH- hydrogen gas, and. The OH- and Li+ LiOH is produced when ions create an ionic connection.
Consequently, the products are LiOH and H2.
Group 2A Metal with Water
What results from the reaction between calcium and water?
Determine the reactants and the metal type.
We can tell from the problem that Ca and water are the reactants. On the periodic table, calcium is found in the second column and fourth row, making it a Group 2A metal.
Record the reaction and list the byproducts.
The typical reaction formula for Group 2A metals and water is now updated to include calcium.
Ca(s)+2H_2O(l) -> Ca(OH)2(aq)+H_2(g)
Calcium and other alkaline metals react very minimally with water. In this process, water produces hydroxide ions together with hydrogen gas and calcium is ionized to generate C a 2 +. Calcium ions and hydroxide ions interact ionically to generate C a ( O H ) 2.
Therefore, the end results are C a ( O H ) 2 and H_2.
