Fe⁰ + 2 H⁺¹Cl⁻¹ = Fe⁺²Cl₂⁻¹ + H₂⁰
the iron is oxidized
the hydrogen is reduced
hope this helps!
Answer:
An antenna
Explanation:
Radio waves are received by antennas
Answer:
1. Heating hydrogen gas from 60°C to 80°C: Entropy increases
2. Subliming dry ice: Entropy increases
3. Forming sucrose crystals from a supersaturated solution: Entropy decreases
4. Condensing water: Entropy decreases
Explanation:
Entropy is a measure of systems disorder. The higher the entropy the higher the disorder. So for the firs example if we heat a gas, molecules move faster, disorder is higher. For second example we are making disordered gas from very ordered crystals also increase in disorder. For 3rd example we are obtaining crystals which brings order. And for the fourth example we make liquid from gas which is also more order.
Answer:
ADP
Explanation:
If you start with Triphosphate (tri meaning 3)
You end up with a P on the other end, and you need ADP (Di meaning 2), and some extra energy.
<span>We would use the ideal gas equation. PV = NRT
No of moles of ag2o = 30/ 231.735 = 0.12944
The chemical reaction is given by
2 Ag2O = 4 Ag + O2
2* 0.12944 of Ag2O requires 0.12944 of O2
So we have P * 1 = 0.258 * 8.2 * 450
P = 952.02 atm</span>
