The correct response is A. Only the Fe is unbalanced.
Answer: 5.1 gram
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require = 1 mole of
Thus 0.41 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
Moles of HCl left = (0.55-0.41) = 0.14
Mass of left =
Thus 5.1 g of hydrochloric acid could be left over by the chemical reaction.
Explanation:
When emission of industrial gases like sulfur dioxide, carbon dioxide and nitrogen oxide combine with water then the rain that consists of these acids fall into the atmosphere is known as acid rain.
When these gases combine with water then they result in the formation of an acid that is present in an aqueous phase.
So, when sulfur trioxide combines with water then the reaction will be as follows.
Hence, we can conclude that sulfuric acid is formed when sulfur trioxide gas reacts with water.

Trainers use this substance because the reaction of the product on the skin is an exothermic one. This produces a feeling of warmth and heat. Heating an injury like a sprain with warmth or heat increases blood flow to the area and promotes healing as the flow of blood carries the necessary substances for healing.
