Answer:

Liquids and gases are called fluids because they can be made to flow, or move.

 In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container. So that they're called fluids.

Fluids are liquid and gases. They take the shape of their containers. They are called fluids because of their ability to flow.

Fe2O3 + CO --> Fe + CO2

satela [25.4K]

Answer:

The answer to your question is

1.-Fe₂O₃

2.- 280 g

3.- 330 g

Explanation:

Data

mass of CO = 224 g

mass of Fe₂O₃ = 400 g

mass of Fe = ?

mass of CO₂

Balanced chemical reaction

Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂

1.- Calculate the molar mass of Fe₂O₃ and CO

Fe₂O₃ = (56 x 2) + (16 x 3) = 160 g

CO = 12 + 16 = 28 g

2.- Calculate the proportions

theoretical proportion Fe₂O₃ /3CO = 160/84 = 1.90

experimental proportion Fe₂O₃ / CO = 400/224 = 1.78

As the experimental proportion is lower than the theoretical, we conclude that the Fe₂O₃ is the limiting reactant.

3.- 160 g of Fe₂O₃ --------------- 2(56) g of Fe

400 g of Fe₂O₃ --------------- x

x = (400 x 112) / 160

x = 280 g of Fe

4.- 160 g of Fe₂O₃ --------------- 3(44) g of CO₂

400 g of Fe₂O₃ -------------- x

x = (400 x 132)/160

x = 330 gr

When monovalent cation (X) binds to divalent anion (Y) it will form

Romashka-Z-Leto [24]

When a monovalent cation X binds to a divalent anion Y, a compound with the formula $X_2Y$ would be formed.

A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be $X^+$

A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be $Y^2^-$

Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of $X^+$ would be required to successfully bind $Y^2^-$

$Y^2^-$ + $X^+$ + $X^+$ ----> $X_2Y$

Answer:

A and B are unfavorable reactions.

Explanation:

In chemical thermodynamics, an endergonic reaction is also called a nonspontaneous reaction or an unfavorable reaction. it's a chemical reaction in which the change in free energy is positive, and energy is absorbed.

In chemical thermodynamics, an exergonic reaction is also called a spontaneous reaction or a favorable reaction. it's a chemical reaction in which the change in free energy is negative.

ΔG>0

If the Gibbs free energy of the reaction is positive than the reaction will be non spontaneous .

If the Gibbs free energy of the reaction is negative than the reaction will be spontaneous

Gibbs free energy is an energy which that can be use to convert into useful work.

ΔG=ΔH-TΔS

with ΔG= Gibbs free energy

with ΔH = enthalpy of reaction

with T = temperature of eh reaction

ΔS = Entropy change

The reaction A: Pi+glucose⟶glucose-6-phosphate+H2O

The ΔG is positive. This is an nonspontaneous reaction or an unfavorable reaction

The reaction B: Pi+fructose-6-phosphate⟶fructose-1,6-bisphosphate+H2O

The ΔG is positive. This is an nonspontaneous reaction or an unfavorable reaction.

The reaction C: ATP+H2O⟶ADP+Pi

The ΔG is negative. This is a spontaneous reaction or a favorable reaction.

A and B are unfavorable reactions.
