Answer:
In roasting, air in large amounts, sometimes enriched with oxygen, is brought into contact with the sulfide mineral concentrate. This is done at elevated temperatures when oxygen combines with sulfur to form sulfur dioxide and with the metal to form oxides, sulfates and so on. ... Roasting is an exothermic reaction.
calcination as "heating to high temperatures in air or oxygen
Explanation:
Answer:
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with a definite volume.
Explanation:
I honestly don't know if that's right...
Answer : The isotopic representation of silicon atom is:
Explanation :
Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.
Isotope notation or nuclear symbol : It is also called as nuclear notation. In isotopic notation we can easily determine an isotope's mass number, atomic number, the number of neutrons and protons in the nucleus.
The general isotopic representation of an atom is:
where,
Z = Atomic number of the atom
A = Mass number of the atom
X = Symbol of the atom
As we are given that the atom is, silicon.
Atomic number of Si atom = 14
Mass number of Si atom = 29
The symbol of silicon = (Si)
The isotopic representation of silicon atom is:
Answer: it’s carbon dioxide
Explanation:
This is it because decomposition takes place when carbonic acid breaks down So that’s why I put carbon dioxide
B. 100 meters is only equal to 1 hectometer.
