<span>At STP 1 mol of an ideal gas has a volume of 22.4 L.
We assume (from the question) that the methane has an ideal behavior.
Hence if 1 mole of an ideal gas ccupies a volume of 22.4 L
Then 0.75 mole occupies X
Hence X * 1 = 0.75 * 22.4
X = 16.8L</span>

In the above equation, when the 3 mol Copper sulfate reacts with 2 mol lithium phosphate
, it will produce 2 mol Copper phosphate and 3 mol Lithium sulfate
.
Answer:
Cl-
Explanation:
The equation of the reaction is;
H+(aq)+Cl-(aq)+H2O(l)→H3O+(aq)+Cl-(aq)
Lewis base refers to substances that can donate a lone pair of electrons(e.g OH^-, Cl^- etc) or a pair of nonbonding electrons.(eg NH3, H20 etc). A Lewis base is therefore an electron-pair donor. They are easily recognized because they often have lone pairs or are negatively charged species.
If we look at the products, Cl- is a Lewis base because it is a lone pair donor. We see this more clearly because the specie is negatively charged.
Answer:
When the drumstick hits the drum, it exerts a force on the drum. Newton’s third law states that if a force from object A is exerted onto object B, then an equal and opposite force from object B is exerted onto object A. By Newton‘s third law, the drum also exerts a force on the drumstick.
I hope this helps! :)
