Answer:
Homogenous mixture
Explanation:
Homogenous mixtures like ice cream appear to be uniform, and you cannot see their individual components.
Answer:
108.9g of Silver can be produced from 125g of Ag2S
Explanation:
The compound Ag2S shows that two atoms of Silver Ag, combined with an atom of Sulphur S to form Ag2S. We can as well say the combination ration of Silver to Sulphur is 2:1
•Now we need to calculate the molecular weight of this compound by summing up the molar masses of each element in the compound.
•Molar mass of Silver Ag= 107.9g/mol
•Molar mass of Sulphur S= 32g/mol
•Molecular weight of Ag2S= (2×107.9g/mol) + 32g/mol
•Molecular weight of Ag2S= 215.8g/mol + 32g/mol= 247.8g/mol
•From our calculations, we know that 215.8g/mol of Ag is present in 247.8g/mol of Ag2S
If 247.8g Ag2S produced 215.8g Ag
125g Ag2S will produce xg Ag
cross multiplying we have
xg= 215.8g × 125g / 247.8g
xg= 26975g/247.8
xg= 108.85g
Therefore, 108.9g of Silver can be produced from 125g of Ag2S
Answer: I think It might be 1 M???
Explanation: Sorry I'm not in high school I put the wrong age
The ammonium iodide solution is converted into a buffer by the addition of ammonia (NH₃).
<h3>What is a buffer solution?</h3>
- A solution which is formed by the addition of weak acid and its conjugate base or weak base and its conjugate acid.
- They resist a change in pH of the solution when an acid or alkali added to them.
<h3>Which is to be added to the given solution to convert it into a buffer?</h3>
The given solution contains 0.21 M ammonium iodide (NH₄I). This is a salt of a weak base(NH₃) and a strong acid(HI).
NH₄I(s) → NH₃(g) + HI(g)
Where the salt is ionic. So, in aqueous solution it dissociates into NH₄⁺ and I⁻
The ammonium ion NH₄⁺ is the conjugate acid of the weak base NH₃.
So, the mixture of this weak base NH₃ and its conjugate acid NH₄⁺ converts the solution into a buffer.
Therefore, one liter of the given solution could be converted into a buffer by the addition of a weak base NH₃.
