3.9L
Explanation:
Initial volume = 25L
Final volume = 28.9L
The initial volume is the volume of the liquid without the metal in originally in the container. It is 25L
After adding the metal, the volume changes to 28.9L
Final volume = Initial volume + volume of metal
To find the volume of metal make it the subject of the expression;
Volume of metal = Final volume - initial volume = 28.9 - 25 = 3.9L
The volume of irregular solids are measured by immersing them in water. The change in volume gives their volume.
Sometimes the volume of water displaced is the volume of the solid.

The chemical reaction is expressed as:
<span> 4KO2+2CO2→2K2CO3+3O2
</span>
We are given the amount of KO2 to be used in the reaction. This will be the starting point of our calculations. We do as follows:
0.425 mol KO2 ( 3 mol O2 / 4 mol KO2 ) = 0.319 mol O2 produced
Hope this answers the question. Have a nice day.
Huh what type of question is that?!
The correct response would be 3. The alkaline earth metals would tend to lose its valence electrons, in this case 2 of them at different energy levels, to form the same respective ion, which is +2.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Next, we identify the limiting reactant by computing the available moles of ethane and the moles of ethane consumed by 60.0 grams of oxygen:
Thus, we notice there are less available moles, for that reason, the ethane is the limiting reactant. Finally, we can compute the produced moles of water by:
Best regards.
