Answer:
a. Bronze
b. Copper
Explanation:
a. The alloy formed <u>from the mixture of molten tin and molten copper, with copper having the over triple of the quantity of tin</u>, is bronze. Although, these two metals are often not the only metals present in bronze.
b. The solvent in this mixture is molten copper. This is because, <u>it has the larger percentage of the constituents</u> and hence can easily allow other constituents to be dissolved in it.

Answer:
V₂ = 1866.32 mL
Explanation:
Given data:
Initial temperature = 27.8°C (27 + 273.15 K = 300.15 k)
Initial volume = 1500 mL
Final volume = ?
Final temperature = 100.0°C (100.0 + 273.15 K = 373.15 K)
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
1500 mL / 300.15 k = V₂ / 373.15 K
V₂ = 1500 mL× 373.15 K/ 300.15 k
V₂ = 560175 mL. K /300.15 k
V₂ = 1866.32 mL
Answer:
Iodide concentration: 0.02M I⁻
Persulfate concentration: 0.02M S₂O₈²⁻
Explanation:
In chemistry, a dilution is the process in which the concentration of solute is reduced by addition of more solvent.
Iodide (KI → I⁻), has a concentration of 0.20M. If you add 5mL resulting in a final volume of 50mL, the final concentration decreases in:
0.20M × (5mL /50mL) = <em>0.02M I⁻</em>
The persulfate ion (K₂S₂O₈ → S₂O₈²⁻) has a concentration of 0.10M in 10mL that result in a final volume of 50mL. That means final concentration is:
0.10M × (10mL /50mL) = <em>0.02M S₂O₈²⁻</em>
