Yes u can do it but using all of ur answer
Answer:
NH3
Explanation:
there is one nitrogen and 3 hydrogen
Answer:
200 ppm
Explanation:
Sodium nitrate is used as a preservative in hotdog to preserve the colour of meat. 200 ppm of sodium nitrate (NaNO3) can be used in a hot dog. A human body can accept 3.7 mg of Sodium nitrate as per kg weight of body. So, excessive use of sodium nitrate in hot dog can harm the human body and produce diseases.
Answer:
5.83 mol.
Explanation:
- From the balanced reaction:
<em>2Al + 3Ag₂S → 6Ag + Al₂S₃,</em>
It is clear that 2 mol of Al react with 3 mol of Ag₂S to produce 1 mol of Ag and 1 mol of Al₂S₃.
Al reacts with Ag₂S with (2: 3) molar ratio.
<em>So, 2.27 mol of Al reacts completely with 3.4 mol of Ag₂S with (2: 3) molar ratio.</em>
<em />
- The limiting reactant is Ag₂S.
- The excess "left over" reactant is Al.
The reamining moles of excess reactant "Al" = 8.1 mol - 2.27 mol = 5.83 mol.
Independent atoms have high potential energy,and they are highly unstable.
And when they form bonds their potential energy decreases and they become stable.
Hence bonded atoms are stable and have relatively low potential energy than independent atoms.
