If 0. 200 moles of agno₃ react with 0. 155 moles of h₂so₄ according to this unbalanced equation below, what is the mass in grams of ag₂so₄ that could be formed? agno₃(aq) + h₂so₄ (aq) → ag₂so₄ (s) + hno₃ (aq)
Balance the reaction.
a AgNO₃ (aq) + b H₂SO₄ (aq) → c Ag₂SO₄ (s) + d HNO₃ (aq)
Count the atoms of each element on either side:
• Ag : a = 2c
• N : a = d
• O : 3a + 4b = 4c + 3d
• H : 2b = d
• S : b = c
Let c = 1. Then a = d = 2 and b = 1 and all the counts are consistent. So the balanced reaction is
2 AgNO₃ (aq) + H₂SO₄ (aq) → Ag₂SO₄ (s) + 2 HNO₃ (aq)
which is to say 1 mol H₂SO₄ is needed for every 2 mol AgNO₃ to produce 1 mol Ag₂SO₄.
We start with 0.200 mol AgNO₃, so we can use up at most 0.100 mol H₂SO₄ (and leave an excess 0.055 mol). These react together to produce 0.100 mol Ag₂SO₄
Ag₂SO₄ has a molar mass of about 311.79 g/mol, so this reaction will produce a mass of
(0.100 mol) (311.79 g/mol) ≈ 31.2 g Ag₂SO₄
Tiny sensors in smartphone could be used to determine the position of the phone on the earth’s surface by measuring the earth’s magnetic field. A current i is applied to a slice of semiconductor as shown in figure 1(a).
The reason why the electrons collect at the top of the edge of the slice is because; surface charge density is inversely proportional to the radius of surface.
What are electron slices in semi conductors?Electron slices are said to be little parts of electrons in any medium. Now, we want to find out from the attached diagrams the reason why electrons in figure 1a collect at the top of the edge of the slice as seen in figure 1b.
The reason why the electrons collect at the top of the edge of the slice that in relation to the attraction upwards, Voltage (V) and Magnitude of the magnetic field (B) is due to the fact that surface charge density is inversely proportional to the radius of surface.
This is proved by the formula:
σ ∝ 1/R

σ is surface charge density
R is Radius of the surface.

Which excerpt from "the enigma machine" supports the claim that german soldiers accidentally helped the allies figure out the enigma codes? with the right settings, the recipient only needed to type in the encrypted text and the message would light up in plain text. To use the enigma machine, an operator typed a message into the machine, which would be scrambled by three rotors. . . The polish intelligence developed the "bomba", a complicated system of wires and rotors to scan and decode messages within hours. Typing in messages was a boring task, so operators took shortcuts, like choosing three letters in a row or other simple, predictable patterns.
The correct option is C. The assertion that German soldiers unintentionally assisted the Allies in cracking the Enigma codes is supported by "The Enigma Machine." To quickly scan and decipher messages, the Polish intelligence created the "bomba," a complex system of cables and rotors.
Who cracked Enigma first?In the early 1930s, the Poles, under the direction of mathematician Marian Rejewski, cracked the Enigma code for the first time. The British received intelligence from the Poles in 1939 as the possibility of a German invasion increased. The British established a covert code-breaking team known as Ultra, led by mathematician Alan M.
According to "The Enigma Machine," the Allies anticipated the Germans' coding method to be complex. German engineer Arthur Scherbius created the Enigma machine at the end of World War I. In his invention, he made use of rotors and an electrical path.
Thus, The right answer is C. In order to scan and decode messages within hours, Polish intelligence created the "bomba," a complex system of wires and rotors. An excerpt from "the enigma machine" supports the idea that German soldiers unintentionally assisted the allies in cracking the enigma codes.

The volume of a gas is 400. 0 ml when the pressure is 1. 00 atm. At the same temperature, what is the pressure at which the volume of the gas is 2. 0 l?.
Answer:
0.2 atm
Explanation:
V1 = 400.0 ml = 0.400 l, P1 = 1.00 atm
V2 = 2.0 l, P2=?
At the same temperature, P1 * V1 = P2 * V2, so
P2 = P1 *(V1/V2) = 1.00 * (0.4/2) = 0.2 atm
