Ferrosoferric oxide and hydrogen gas are the products of this reaction.

<h3><u>Explanation:</u></h3>

Iron is the metallic element with the atomic number 26. It has a valency of both 2 and 3 which forms two types of oxide - ferrous oxide and ferric oxide.

Iron reacts with water with a metal and acid reaction, which forms both the iron oxide and evolves hydrogen gas. The hydrogen gas escapes the system and the mixture of iron oxide is left over in the system. The mixture is denoted by the formula Fe_3O_4 and is called ferrosoferric oxide.

This reaction is reversible and is reversed if hydrogen gas is passed over heated ferric oxide in increased pressure.

How many ml of a 2.0 m nabr solution are needed to make 200.0 ml of 0.50 m nabr?
gogolik [260]

To solve this we use the equation,

 

<span> M1V1 = M2V2</span>

 

<span> where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.</span>

 

<span>2.0 M x V1 = 0.50 M x 200 mL</span>

<span>V1 = 50 mL needed</span>

From the following balanced equation,
ArbitrLikvidat [17]

Answer:

9.72 grams.

Explanation:

From the equation, 4 moles of NH₃ produce 6 moles of  water.

Therefore the reaction to product ratio of  NH₃ to H₂O is 4:6

and 2:3 into its simplest form.

The number of moles of NH₃ in 6.12 g is:

Number of moles=mass/ RMM

=6.12 g/17 G/mol

=0.36 moles.

Therefore the number of moles of H₂O produced is calculated as follows.

(0.36 Moles×3)2 = 0.54 moles

Mass= Number of moles × RMM

=0.54 moles×18g/mol

=9.72 grams.
