Answer:
Yes. These chemicals named barium chloride and calcium carbonate have been named properly. But silicon oxide has not been named correctly, an oxide of silicon is named as silicon dioxide not silicon oxide.
Explanation:
In chemistry while naming chemicals there are certain rules and naming the chemicals as per these rules is known as chemical nomenclature. The IUPAC's rule for chemical nomenclature of inorganic compounds can be read in a book named as red book.
<u>By sign convention, a cation is named first followed by an anion.</u> For example, in barium chloride (BaCl₂), barium which is represented by symbol Ba²⁺ is a cation and therefore written before chloride (Cl⁻) which is an anion. Similarly calcium carbonate is represented as CaCO₃.
As per the valency of silicon, it forms a dioxide with oxygen atom and it is represented as SiO₂.
Answer:
You should not use an open flame to heat the solvent and the solvent should be heat in a stoppered flask to vapour away from the open flame

Answer:
All isotopes have 24 protons.
Explanation:
Isotope:
The isotope of an element have same number of protons but different number of neutrons.
In given question chromium has four isotopes Cr-50, Cr-52, Cr-53 and Cr-54.
In each isotope the number of protons are 24 but the number of neutrons are different.
The number of protons are also equal to the number of neutrons and it is also the atomic number so the atomic number of all chromium isotope is same.
The number of neutrons in Cr-50 = 50-24= 26
So, chromium 50 has 26 neutrons.
The number of neutrons in Cr-52 = 52-24= 28
So, chromium 52 has 28 neutrons.
The number of neutrons in Cr-53 = 53-24= 29
So, chromium 53 has 29 neutrons.
The number of neutrons in Cr-54 = 54-24= 30
So, chromium 54 has 30 neutrons.
