3. How many moles of Fe2(SO4)3 are present in 300 grams of Fe2(SO4)3 ?
SOLUTION:
Step 1: Calculate the molar mass of Fe₂(SO₄)₃.
[tex]\begin{aligned} \text{molar mass} & = \text{2(55.85 g) + 3(32.07 g) + 12(16.00 g)} \\ & = \text{399.9 g} \end{aligned}[/tex]
Step 2: Calculate the number of moles of Fe₂(SO₄)₃ by using dimensional analysis.
[tex]\begin{aligned} \text{moles of} \: \text{Fe}_2(\text{SO}_4)_3 & = \text{300 g} \: \text{Fe}_2(\text{SO}_4)_3 \times \frac{\text{1 mol} \: \text{Fe}_2(\text{SO}_4)_3}{\text{399.9 g} \: \text{Fe}_2(\text{SO}_4)_3} \\ & = \boxed{\text{0.750 mol}} \end{aligned}[/tex]
Hence, there is 0.750 mol of Fe₂(SO₄)₃ in 300 g of Fe₂(SO₄)₃.

5. . What is the purpose of SCI?
Answer:
Science aims to explain and understand. What is science? Science as a collective institution aims to produce more and more accurate natural explanations of how the natural world works, what its components are, and how the world got to be the way it is now.
step-by-step explanation:
6. What is the purpose of SCI?Can you enumerate the elements of an SCI?
Answer:
Science aims to build knowledge about the natural world. This knowledge is open to question and revision as we come up with new ideas and discover new evidence. Because it has been tested, scientific knowledge is reliable.
These elements have evolved over the centuries, and they have become accepted by both scientists and philosophers of science as sound basic principles.

9. The Ecell at steady state condition of Fe3+ + Cu→Cu2+ + Fe2+
Answer:
Two important important parameters that can be determined from a cell potential are the equilibrium constant for the cell reaction and the free energy change for the cell reaction.
Determining the Equilibrium Constant from Eocell
Determining the Standard State Free Energy Change from Eocell
Determining the Non-Standard Free Energy Change
Determining the Equilibrium Constant from Eocell
To calculate the equilibrium constant for an electrochemical cell we need to know:
the standard state potential for a cell
the half-reactions involved
The Nernst equation is used in calculating the equilibrium constant.
Nernst Equation
At equilibrium Q = K. Substituting in K for Q, and the values for R, T, and F, we get:
Nernst Equation
Example: Find the value of the equilibrium constant at 25oC for the cell reaction for the following electrochemical cell:
Cu | Cu2+(1 M) || Ag+(1 M) | Ag.
Write the equations for the cell half-reactions, calculate the standard cell potential, and determine the number of electrons transferred.

Answer. Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron(III) oxide (ferric oxide).
13. What are the 5 Elements of SCI?Two types of SCI(statement of comprehensive income) Two types of corporation?
Answer:
1.According to Yogananda (1957) , the universe is made of the five elements, that is, earth, air, water, fire, and ether. These elements mutually support, check and balance.
2.Both cover the same time period, but the statement of comprehensive income has two major sections: net income (derived from the income statement) and other comprehensive income (e.g., hedges).
3.There are two broad types of business corporations: publicly held (or public) and closely held (or close or private) corporations. Again, both types are private in the sense that they are not governmental.

19. fe + h2S04 = fe2(SO4)3 + h2 =
Good Day
Given:
Fe + H₂S0₄ ⇒ Fe₂(SO4)₃ + H₂The type of reaction is single replacement in which Fe (iron) is more active that H (hydrogen) thus, it replaces the place of Hydrogen. Fe can only replace Hydrogen since they have the same charge. Fe cannot replace the place of SO₄ since they have different charge.
To Balance the equation:
2Fe + 3H₂S0₄ ⇒ Fe₂(SO4)₃ + 3H₂ ↓ ↓ Reactant Product Fe = 2 Fe = 2 H = 6 H = 6 S0₄ = 3 S0₄ = 3We balance the chemical equation since atoms are not destroyed in the process and the mass is conserved. The mass of the reactant is equal to the mass of the product which also means, the number of atoms of elements in both the product and reactant are equal.

20. The climate of a desert is usuallyHot and drya. rainy and humidb. dark and wetc. wet and cold
Answer:
Hot and dry
Explanation:
A desert is a barren area where very little precipitation occurs and have very few flora and fauna. This is because of its extreme temperatures and climate conditions. Only a few species can survive in the desert. The most common example for plants is the Cactus and Camel for animals.
Most deserts are hot and dry. However, there are two types of deserts; hot and cold. Cold deserts are usually found in mountianous areas in the temperate regions. These deserts have hot summers but extremely cold winters. Examples of plants that live here are plants with spiny thin leaves (cacti) and grasses. Some animals on cold deserts are antelope and prairie animals.

21. where would you go ? desert or the bottom of the ocean with super super dark water or space?
I would choose to explore the ocean with super dark water. I am fascinated by marine life and the mysteries hidden deep in the ocean floor. While darkness can be daunting, I find it exciting to explore the unknown and discover new species of creatures that thrive in such extreme conditions. For me, the ocean is also calming and I enjoy the tranquility of being surrounded by water. Overall, the idea of diving into the deep ocean and discovering new things excites me the most of the three options presented.
