Single-displacement reaction occurs when aluminum reacts with copper nitrate.
Single-displacement reaction is the type of chemical reaction that occurs when aluminum (Al) reacts with copper nitrate (Cu(NO3)2). In this type of reaction, aluminum takes the place of copper and produced aluminium nitrate.
Aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate because potassium nitrate (KNO3) is a stable compound which held each other very tightly so we can conclude that Single-displacement reaction occurs when aluminum reacts with copper nitrate.

Answer:positive electrode
Explanation:
Anode can also be referred to as positive electrode in a cell
Answer:
The wavelength of a sound is the distance between adjacent identical parts of a wave. The frequency is the same as that of the source and is the number of waves that pass a point per unit of time.
I believe the answer is A.
Hope this helps! ^^
The balanced equation for the combustion of methane is:
CH4 + 2O2 --> CO2 + 2H2O
Therefore for every mole of CH4 burned, one mole of CO2 is produced. We can use the mass of CO2 and its relative molecular mass to calculate the moles of CO2 produced. The rmm of CO2 is 44.0 g/mol, therefore the numbers of moles of CO2 = 11/ 44.0 = 0.25 moles. Therefore 0.25 moles of CH4 were burned, which has a rmm of 16.0 g/mol, therefore the mass of CH4 burned was 0.25 * 16.0 = 4.0 g
