Answer:
Thermite Reaction
Explanation:
The reaction between iron(III) oxide and aluminum produces aluminum oxide and iron. The chemical equation of the reaction is: This reaction is known as a thermite reaction and is highly exothermic. The large amount of heat released is enough to melt oxygen and aluminum.
I don’t know but I think it would be products... that’s the best I can give. I’ll look more into it
The charges on a droplet can be used to represent the number of electrons carried by this droplet.
In other words:
a droplet having a charge of 1.60 x 10^-19 has 1.60 x 10^-19 electrons while a droplet having a charge of 3.15 x 10^-19 has <span>3.15 x 10^-19 electrons.
From the observations:
The fact that the droplets carried different charges signifies the fact the different droplets carried different numbers of electrons</span>
Answer:
a. Plum pudding model
Explanation:
The plum pudding model of the atom was proposed by J.J. Thomson. It was the model he derived from his experiment on the gas discharge tube.
J.J Thomson was the first person to discover electrons which he called cathode rays because in the discharge tube, they emanate from the cathode.
- This led him to suggest the plum pudding model of the atom.
- The model reflects electrons being surrounded by a volume of negative charges.
