Answer:
Number of moles of Fe = 10 mol
Number of moles of CO₂ = 15 mol
Explanation:
Given data:
Number of moles of iron oxide = 5 mol
Number of moles of carbon monoxide = 25 mol
Number of moles of product = ?
Solution:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Now we will compare the moles of reactant with product.
Fe₂O₃ : Fe
1 : 2
5 : 2×5 = 10 mol
Fe₂O₃ : CO₂
1 : 3
5 : 3×5 = 15 mol
CO : Fe
3 : 2
25 : 2/3×25 = 16.7 mol
CO : CO₂
3 : 3
25 : 25
Less number of moles of Fe and CO₂ are formed by iron oxide thus it will act as limiting reactant while CO is inn excess.
Answer:
Rewrite the following sentence in reported speech

I do not believe you're asking this...
OK. Sulfur has a total of 24 isotopes. Every isotope has 16 protons and the number of neutrons ranges from 10 to 33 inclusive.
Phosphorus has a total of 23 isotopes. They have 15 protons, and between 9 and 31 neutrons inclusive. So here we go.

Answer:
The correct option is;
Group 12
Explanation:
A metallic element that is shiny and silver colored that can exist in the +1 and +2 ionic states and which forms a bright red compound with sulfur is mercury, Hg
The compound formed between mercury and silver is one of the earliest synthetic compound also known as vermilion and cinnabar. The bright red pigment of the HgS is used widely and is one of the most favorite pigment found in medieval European outstanding works of arts and in Chinese decorated wares made of lacquer as well as in mesoAmerica.
Answer:
The correct answer to the following question will be Option C.
Explanation:
- The theory seems to be the context within which findings are explained as well as possible predictions are made. This theoretical perspective discusses the factors behind the results as well as the laws.
- Theories have been used in scientific knowledge to give wide interpretations to accommodate observed facts in case the root reason is still yet to be found as well as characterized.
So that Option C will be the right answer.
