How many moles of Fe(OH)2 are required to produce 7.4 moles of Fe3(PO4)2
Answers
Considering the reaction stoichiometry, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.
The balanced reaction is:
3 Fe(OH)₂ + 2 H₃PO₄ → Fe₃(PO₄)₂ + 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- Fe(OH)₂: 3 moles
- H₃PO₄: 2 moles
- Fe₃(PO₄)₂: 1 mole
- H₂O: 6 moles
Then you can apply the following rule of three: if by reaction stoichiometry 1 mole of Fe₃(PO₄)₂ requires 3 moles of Fe(OH)₂, 7.4 moles of Fe₃(PO₄)₂ require how many moles of Fe(OH)₂?
amount of moles of Fe(OH)₂= 22.2 moles
Finally, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

Answer:
The correct answer is option A. "a mineral or metal with economic usefulness".
Explanation:
An ore is defined as a rock or sediment found in nature which contains a mineral or metal with economic usefulness. The minerals or metals in the ore must be extracted before they could be used, and typically, they are refined via smelting. The ore grade is defined according to the concentration of the mineral or metal beneath the rock or sediment.

H2O + CO2 --> H2CO3
Ratio between water and CO2 is 1:1. So we can say that for every Mole of CO2, we need 1 Mole of water to produce 1 Mole of H2CO3. Thus as n=m/M we can find n = 528/44.01 = 11.997 ~ 12Mol.
Therefore, we need 12 moles of water.
Answer:
12 moles
Explanation:
The reaction will form carbonic acid:
CO₂ + H₂O ⇒ H₂CO₃
For 528 g of CO₂, the number of moles (n) will be:
n = mass/molar mass
n = 528/44.01
n = 12 moles of CO₂
The stoichiometry is 1 mol of CO₂ reacts with 1 mol of H₂O, so 12 moles of CO₂ need 12 moles of H₂O.

The earth's plates move, slide alongside one another, pull apart, or collide. Therefore, option (A) is correct.
What is it called when tectonic plates collide?
If two tectonic plates of the earth collide there is the formation of a convergent plate boundary. One of the converging plates will usually move beneath the other is called subduction.
The fluids are released from the rock as the sinking plate moves deeper into the mantle, causing the overspreading mantle to partially melt. The new magma rises and forms volcanoes.
When two plates are pulling apart from each other, it is a divergent plate boundary. The magma rises from deep within the Earth along these boundaries and forms a new crust on the lithosphere. Most divergent plate boundaries form submarine mountain ranges known as oceanic spreading ridges and are underwater.
Another type of plate boundary that occurs when tectonic plates slide alongside one another is known as a transform plate boundary. As the earth's plates rub each other, large stresses can cause the rock to break, resulting in earthquakes.

Certain conditions provide less than 10% yield of NH3 at equilibrium. Which statement describes this equilibrium?
A. The Keq is large and products are favored.
B. The Keq is small and products are favored.
C. The Keq is large and reactants are favored.
D. The Keqis small and reactants are favored.
E. The conditions of the reaction must be known to answer the question
To answer you must know that the equilibrium yield is the quantity of product obtained.
In this case it is 10% of NH3.
That means that the equilibrium is more favorable to the reactants.
Given that Ke relates the concentration of products / concentration of reactants, the answer is the Ke is small and reactants are favored
Final answer:
This equilibrium has a low yield of NH3 and can be improved by adjusting the conditions and using the principles of Le Chatelier.
Explanation:
This equilibrium can be described as an equilibrium with a low yield of NH3. The fact that less than 10% yield of NH3 is obtained suggests that the forward reaction (N2(g) + 3H2(g) -> 2NH3(g) + energy) is not favored under the given conditions. To increase the yield of NH3, the conditions can be adjusted to shift the equilibrium towards the product side.
The Le Chatelier's principle can be applied to achieve a higher yield of NH3. One possible way is to increase the concentration of the reactants (N2 and H2) or decrease the concentration of the product (NH3). Another way is to increase the temperature, as this reaction is exothermic. By increasing the temperature, the equilibrium will shift in the reverse direction to consume the excess energy.
In summary, this equilibrium is characterized by a low yield of NH3, which can be improved by adjusting the conditions and using the principles of Le Chatelier.
