Answer:
Li(s) + H2O(l) -----> LiOH(aq) + H2(g)
Ca(s) + 2H2O(l) ---------------> Ca(OH)2(aq) + H2(g)
Explanation:
Metals react with water to yield the metal hydroxide and hydrogen gas as shown in the answer above.
The reaction equations were balanced, the number of atoms of each element on both side of the reaction equation is exactly the same.
This is the way to write a balanced reaction equation for the species shown in the question.
Answer:
84.6 mL
Explanation:
To get the total volume of soultion we must add the given volumes together.
4.21 mL + 80.4 mL = 84.6 mL
“Flow is the volume of fluid that passes in a unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), or other various units.”

After one half life initial amounts gets half so :-
- First half life :- 350÷2 = 175 grams
- second half life :- 175 ÷2 = 87.5 grams
- third half life :- 87.5 ÷2 = 43.75 grams
so at last of third half life amount left = 43.75 grams
each time amount get half
