CaCO₃ → CaCl₂
Ca = 40, C = 12, O = 16, Cl = 35.5
100 →111
3 → x
x = 3.33g
Na2SO3 and H2SO3 are the possible compounds hence X belongs to group number 1.
Answer:
Because burning a non-renewable resource that is not good for the atmosphere, will always cause some kind of chemical reaction to happen.
Examples of these reactions are...
- Acid rain, a very dangerous disaster.
- Global warming.
- Carbon increases.
A beaker of black powder can be a mixture with different substances (i.e gunpowder: a mixture of sulfur, charcoal, etc.), an element which can probably be carbon (known as black), and a compound as well which can be potassium nitrate. Hence, the answer is D.
