Answer:
NH₄Cl form closer to the end of the tube from which HCl was released.
Explanation:
Ammonia and hydrogen chloride gas react to form ammonium chloride water which can be seen by the formation of intensified fumes.
HCl + NH₃ ⇒ NH₄Cl
Since, the ammonia gas has a lower molecular weight as compared to that of hydrogen chloride gas. According to Graham's law of diffusion, the diffusion rate is inversely proportional to the square root of the molecular mass of the gas. <u>Thus, ammonia will diffuse faster as compared to hydrogen chloride gas. So, the white fumes will form at the side of the hydrogen chloride gas as it's diffusion will be slower and ammonia will diffuse fast and reaches to the gas.</u>
Answer:
C) tellurium (Te) is the correct answer.
It can only do that when one of the components of the mixture is a magnetic
material.
When you have that situation, you pass the magnet over the mixture ... shaking
the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of
the mixture moves toward the magnet, while the nonmagnetic parts of the mixture
couldn't care less about the magnet and they just stay where they are.
Answer:
Mg + AgNO₃ → Ag + Mg(NO₃)₂
Explanation:
A single replacement reaction is one in which an element gets replaced by another in a compound.
In the reaction
Mg + AgC→ Ag + Mg(NO₃)₂
Ag in AgNO₃ is replaced by Mg to give Mg(NO₃)₂.Only one element is getting replaced and hence it is a single replacement reaction.
