Henri Becquerel discovered radioactivity and it was the Curies who made experiments about the concept and became known for their d
TLC means Thin Layer Chromatography. It is a method that can best be described as "Affinity-Based" used in the separation of compounds that are in a mixture.
<h3>What is unreacted p-nitrobenzaldehyde?</h3>
Unreacted p-nitrobenzaldehyde is simply an organic aromatic compound that contains a nitro group para-substituted to an aldehyde. in this case, if it is unreacted, that means it is the same as before the chemical reation.
Note that the question is missing key information hence the general answer.

Answer:
Chemical changes due to heat and pressure
Explanation:
Just took the test, hope this helps! :)
The strength of electrical forces tells about the size of charge on the object.
<h3>What is infer about the strength of electrical forces?</h3>
The strength of the electric force between two charged objects depends on the amount of charge that each object have and on the distance between the two charges. When the amount of charge gets bigger, the force also gets bigger, and when the distance between the two charges gets larger, the force also gets smaller. Electric forces are the attraction present between two charge bodies.
So we can conclude that The strength of electrical forces tells about the size of charge on the object.

Answer:
a) 9424797000 m3
b) 9424797000000 liters
c) 9424797000000 kg
Explanation
Cylinder has a radius of 1 km= 1000 m.
Area Cylinder = π r^2 = 3,141599* (1000m)^2 = 3141599 m2
a) Volume Cylinder= area x Height=3141599 m2* 3000 m= 9424797000 m3
b) 1000 liters= 1m3, 9424797000 * 1000 = 9424797000000 liters
c) densiy = 1000 kg/m3, or 1 kg/ liter, mass= 9424797000 lt * 1kg/lt =
9424797000 kg
