Answer:
2.75 mol
Explanation:
We start with the balanced chemical equation
![FeO+CO--->CO_{2} +Fe](https://tex.z-dn.net/?f=FeO%2BCO---%3ECO_%7B2%7D%20%2BFe)
Clearlt from here we can see that one mole of FeO produces one mole of iron. Thereore it follows that 2.75 mol of FeO will produce 2.75 mol of iron in excess CO
Answer:
ii. < iv. < i. < iii.
Explanation:
Hello,
At first, the entropy is lower in solid-phase systems since their particles are molecularly closer. Next, by knowing that the higher the temperature, the higher the entropy, the gaseous HCl at 25 ºC occupies the second place. After that, it is clear 2 moles of HCl have more entropy than just 1 since the larger the amount of mater the higher the entropy.
Best regards.
Answer:
=0.1293 J
Explanation:
The heat increase is the change in energy for the water ΔH.
ΔH=MC∅ where M is mass, C is the specific heat capacity for water and ∅ is the change in temperature.
M=0.7892g
C(for water) =4.2 J/g°C
∅=0.039 °C
ΔH=0.7892g×4.2 J/g°C×0.039°C
=0.1293 J
The amount of heat energy added to cause the 0.039°C temperature increase is 0.1293 Joules.
Adding substance to a liquid disturbs the lattice in which the liquid settles into to become a solid. To overcome this disturbance, a lower temperature is required. The answer is A, where the prevalence of NaCl is higher than all the others. This means that this compound is present more frequently to affect the lattice more than the others, requiring a much lower freezing temperature.
Answer: The correct answer is
Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
