Answer;

C. increasing the surface area of Fe2O3

Explanation;The rate of reaction refers to the speed at which products are formed from reactants.The rate of any chemical reaction depends on a number of factors which include, surface area, temperature, concentration of reactants among others.When solids and liquids react, increasing the surface area of the solid will increase the rate of reaction. Thus, decrease in the size of particles causes an increase in the total surface area of the solid and therefore increasing the rate of reaction.

Answer from: GreenHerbz206

The balanced reaction is 3Fe₂O₃(s) + CO(g) → 2Fe₃O₄(s) + CO₂(g). Rate of reaction is decrease in the concentration of reactant or increase in the concentration of product with unit time. To increase rate of any reaction either reactant concentration is to be increased. Here (a) addition of Fe₃O₄ will decrease the reaction rate, rather it facilitates the reaction to move backward direction, (b) temperature effect is not clear as it is not mentioned whether the reaction is exothermic or endothermic, (c) if surface area of Fe₂O₃ is increased then more CO molecules can react with more Fe₂O₃ molecules at a time, therefore, reaction rate will increase, (d) increase in the volume of reaction vessel will not affect rate of reaction because reactant and product both have same volume of gaseous compound CO and CO₂ respectively.

So, increase in surface area of Fe₂O₃ would increase rate of the reaction.

Answer from: Quest

answer: $2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

the reaction is type of combination reaction.

explanation:

$? c_5h_5+? fe\rightarrow ? fe(c_5h_5)_2$

on the product side, there are 2 molecules of $c_5h_5$ bonded to fe which means one atom of fe are combined two molecules of $c_5h_5$ . so, balanced chemical equation becomes :

$2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

$a+b\rightarrow ab$

In a modern periodic table, there are seven periods. a period is any horizontal row of the periodic table, and the elements in a period have consecutive atomic numbers. a group is any vertical column in the periodic table, and there are 18 such groups. groups 3â€“12, also known as the â€śbâ€ť group elements, are called transition metals. groups 1â€“2 and 13â€“18, also known as the â€śaâ€ť group elements, are sometimes called the main groups. metals are characterized by malleability, ductility, conductivity, and a tendency to lose electrons. main group metals are found in groups 1 and 2. nonmetallic elements fall on the right-hand side of the periodic table, that is, groups 13â€“18. nonmetals have the tendency to gain electrons and are generally brittle. they can be solids, liquids, or gasses at room temperature. now, label the areas of the modern periodic table using the above information. drag the appropriate labels to their respective targets.
