Answer:
NH4+ is the conjugate acid of the base NH3.
Explanation:
Answer:
Cathode
Cu^2+(aq) + 2e ----> Cu(s)
Zinc is the cathode
Explanation:
The plating of copper is normally done by electrolysis. Electrolysis is generally defined as the chemical decomposition produced by passing an electric current through a liquid or solution containing ions.
There are two electrodes, the anode and the cathode. Recall that electrolysis is not a spontaneous process, hence energy from a battery is required to drive the reaction in the desired direction.
The metal to be plated is normally the cathode while the metal used to plate it is normally the anode. Since copper is to be plated on zinc, zinc must be the cathode while copper will be the anode.
Answer:
a.The waves are absorbed or reflected to capture images
Explanation:
How Things Work: TSA scanners use electromagnetic waves for detection. ... These waves are bounced off the body of the person being scanned to create a three-dimensional image on the computer. The backscatter units instead bounce low-level electromagnetic X-rays off the body to create an image on the computer
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature and moles.
Mathematically, P =
where, k = proportionality constant
Also, formula for initial pressure and volume is as follows.
or,
=
= 30 atm L
Now, we will calculate the value of as follows.
=
= 30 atm L
Hence, as this means that it signifies that gas obeys boyle's law.
