no reaction |
||
K2O and H2 |
||
K2O and H2O |
||
KOH and H2 |
Answer
KOH and H2
Explanation
Following is the balanced reaction between K and H2O
2K(s) + 2H2O(l) ------> 2KOH(aq) + H2(g)
K is an alkali metal ,so, it vigorously reacting with water to produce KOH and H2.
What are the products from the following single-replacement reaction? K( s) + H 2O( l) →...
