Answer: 83.11 torr
Explanation:
According to Dalton's Law of partial pressure, the total pressure of a mixture of gases is the sum of the pressure of each individual gas.
i.e Ptotal = P1 + P2 + P3 + .......
In this case,
Ptotal = 384 torr
P1 = 289 torr
P2 = 11.89 torr
P3 = ? (let the partial pressure of the remaining gas be Z)
Ptotal = P1 + P2 + Z
384 torr = 289 torr + 11.89 torr + Z
384 torr = 300.89 torr + Z
Z = 384 torr - 300.89 torr
Z = 83.11 torr
Thus, the partial pressure of the remaining gas is 83.11 torr.
There can only be two electrons in the innermost shell of an atom so b is the correct answer
Answer:
No. While gold would not react with a silver nitrate solution, nickel would.
Explanation:
Refer to the metal reactivity series.
Reactivity: 
.
Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.
However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.
Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.
Answer:
1.8×10^-2mm or 0.018mm
Explanation:
Density = mass/Volume
But volume= area×thickness
Area= 50ft2= 46451.52cm2
Mass=8oz= 226.7962g
Density= 2.70g/cm3
Thickness= mass/density ×area
= 226.7962/46451.52×2.70= 1.8×10-3cm= 1.8×10^-2mm
A reaction between colorless substances can produce a colored precipitate by formation of new ionic compound.
<h3>What is an ionic compound?</h3>
An ionic compound is a compound that is made up of two elements, one metal and the other non metal, which are held together by an ionic bonding.
When reaction occurs between two colourless substances, colored precipitate results by formation of new ionic compound.
