Answer:
H₂SO₄
Explanation:
Given data:
Number of moles of H₂SO₄ = 15 mol
Number of moles of Fe = 13 mol
Which reactant is limiting reactant = ?
Solution:
Chemical equation:
3H₂SO₄ + 2Fe → Fe₂(SO₄)₃ + 3H₂
now we will compare the moles reactant with product.
H₂SO₄ : Fe₂(SO₄)₃
3 : 1
15 : 1/3×15 = 5
H₂SO₄ : H₂
3 : 3
15 : 15
Fe : Fe₂(SO₄)₃
2 : 1
13 : 1/2×13 = 6.5
Fe : H₂
2 : 3
13 : 3/2×13 = 19.5
Number of moles of product formed by H₂SO₄ are less thus it will act as limiting reactant.
Answer:
A. observing
Explanation:
There are various steps that are involved in a scientific investigation. Observation is the first step of the scientific investigation. In this step, a close examination is laid on the investigation. Observation is collected with the senses and the information is gathered.
In the given excerpt, Clive missed the observation part of the scientific investigation. All the other three steps were followed by Clive. He was not able to observe the situation and so was not able to provide the answers to the questions asked by his classmates.
