How many moles of HCI are needed to react with 0.87 moles of Fe

1.74 moles of HCl

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe + 2HCl —> FeCl₂ + H₂

From the balanced equation above,

1 mole of Fe reacted with 2 moles of HCl.

Finally, we shall determine the number of mole of HCl required to react with 0.87 moles of Fe. This can be obtained as illustrated below:

From the balanced equation above,

1 mole of Fe reacted with 2 moles of HCl.

Therefore, 0.87 moles of Fe will react with = 0.87 × 2 = 1.74 moles

Thus, 1.74 moles of HCl is needed for the reaction.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
