To answer this question, we must first look at the
reactivity series table. From the table, we can see that those which are
located above are the most reactive while those below are less reactive. Which
means that elements cannot replace those elements which are above them.
From the series, platinum is below lead, hence there will
be no reaction.
Answer:
No reaction

Answer:
The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, high surface pressure will form because of the colder air. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze.

Answer:
V HCNsln = 0.9176 L
Explanation:
V HCNsln = ?
∴ m HCN = 31 g
∴ <em>C</em> HCNsln = 1.25 mol/L
∴ molar mass HCN = 27.0253 g/mol
⇒ V HCNsln = (31 g)*(mol/27.0253 g)*(L/1.25 mol) = 0.9176 Lsln
