What is mean by nacl2 in tamil?

"NaCl2" doesn't actually exist as a stable compound. In chemistry, NaCl represents sodium chloride, which is common salt. The subscript "2" indicates the number of atoms of each element in the molecule. However, sodium and chlorine usually combine in a 1:1 ratio, forming NaCl.

Therefore, there is no specific Tamil translation for "NaCl2" since it's not a real compound. However, you could explain it in Tamil as:

"NaCl2 என்பது ஒரு நிலையான சேர்மம் இல்லை. உப்பு என்பது சோடியம் குளோரைடு (NaCl), இதில் சோடியம் மற்றும் குளோரின் 1:1 என்ற விகிதத்தில் இணைந்திருக்கும்."

Translation:

"NaCl2 is not a stable compound. Salt is sodium chloride (NaCl), where sodium and chlorine are combined in a 1:1 ratio."
