Answer:
51.69 g of Fe
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2Fe + 3S —> Fe₂S₃
Next, we shall determine the mass of Fe that reacted and the mass of Fe₂S₃ produced from the balanced equation. This can be obtained as follow:
Molar mass of Fe = 56 g/mol
Mass of Fe from the balanced equation = 2 × 56 = 112 g
Molar mass of Fe₂S₃ = (2×56) + (3×32)
= 112 + 96
= 208 g/mol
Mass of Fe₂S₃ from the balanced equation = 1 × 208 = 208 g
SUMMARY:
From the balanced equation above,
112 g of Fe reacted to produce 208 g of Fe₂S₃.
Finally, we shall determine the mass of Fe needed to produce 96 g of Fe₂S₃. This can be obtained as follow:
From the balanced equation above,
112 g of Fe reacted to produce 208 g of Fe₂S₃.
Therefore, Xg of Fe will react to produce 96 g of Fe₂S₃ i.e
Xg of Fe = (112 × 96)/208
Xg of Fe = 51.69 g
Thus, 51.69 g of Fe is needed for the reaction.

Which of the following reactions is NOT properly classified?
Answer:
I got B a little while back, but the answer might be different for you
sorry if i am wrong
Explanation:
The chemical equation which is not properly classified is CO₂ + 2 H₂O[tex]\rightarrow[/tex] CH₄ + 2 O₂ as this is not combustion reaction.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

The process, when an atom gains electrons is called
Answer:
When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation

1. A student predicted the reaction between hydrogen and oxygen gas would yield 125
mL of water. However, after measuring the water formed in the reaction, the
student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?
Answer:
88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%

Which of these layers is found directly above the Earth's core?
Group of answer choices
Outer core
Mantle
Inner core
Crust
Answer: Mantle
Explanation:
there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.
Answer:
The answer depends on what you are taking about: the outer core or the inner core?
Answer: Mantle
Explanation:
If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer. However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.
I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.

Stimulus refers to events that produce a response in the body due to changes in the environment , therefore response to stimulus is essential for an organism to survive and adapt in its environment.
What is a stimuli?A stimuli is any sensation or action that produces a response in a tissue or organ.
Stimulus is the plural noun of stimuli.
There are two types of stimulus:
external stimulus which comes from outside the body internal stimulus which comes from within the body.The body responds to stimulus in order to adapt to changes in both its external and internal environment.
For example, when the envrionment is hot, the brain receives stimulus from heat receptors and then we start to sweat in order to cool down.
Stimulus are received by sense organs in the body
There are five sense organs in the body;
eye - for sightear - for hearing nose - for smellingskin - for feeling mouth - for tastingSensory receptors in sense organs receives stimulus and send it to the brain through the sensory neurons.
The brain processes the stimulus and send messages back through motors neurons to appropriate organs and tissues to act in response to the stimulus.
