The direction of the magnetic field would be going up.
Answer;
Silver is acting as oxidizing Agent.
Explanation:
The reaction is as follow,
<span> Fe + 3 AgNo</span>₃ → Fe(NO₃)₃<span> + 3 Ag
In above reaction the Iron's oxidation state has changed from 0 to +3, i.e.
Fe</span>⁰ → Fe³⁺ + 3 e⁻
It shows that Iron has lost 3 electrons, Hence, it is oxidized and has transferred 3 electrons to 3 mole of Ag⁺ to reduce it into Ag. Therefore, Iron is acting as reducing Agent.
While, In reaction the Silver's oxidation state has changed from +1 to 0, i.e.
3 Ag⁺ + 3 e⁻ → 3 Ag
It shows that Silver has gained one electron, Hence, it is reduced and has gained 3 electrons from 1 mole of Fe to oxidize it into Fe³⁺. Therefore, Silver is acting as oxidizing Agent.

Here's what I get
Explanation:
You want to dilute the original solution by a factor of 25 in two steps, so you could dilute it by a factor of 5 in the first step, then dilute the new solution by another factor of 5.
A. First dilution
Use a 10 mL pipet to transfer 10 mL of the original solution to a 50 mL volumetric flask. Make up to the mark with distilled water. Shake well to mix.
Use the dilution formula to calculate the new concentration.
B. Second dilution
Repeat Step 1, using the 0.003 970 mol·L⁻¹ solution.
3. Check:
Compare the final concentration with the original
We Are Stardust—Literally. In this infrared image, stellar winds from a giant star cause interstellar dust to form ripples. There's a whole lot of dust—which contains oxygen, carbon, iron, nickel, and all the other elements—out there, and eventually some of it finds its way into our bodies.
Answer:
I believe your answer will be 3--
As the fuel burns, chemical reactions occur within the fuel, breaking up molecules, forming new molecules, and releasing energy. The energy is released as heat, and allows parts of the engine to move. The chemical energy is transformed into thermal energy.
