Answer:
20 moles
Explanation:
4 Fe + 3O₂ → Fe₂O₃
The chemical equation provided is not yet balanced so let's start by balancing it.
4 Fe + 3O₂ → 2 Fe₂O₃
The equation is now balanced with 4 Fe atoms and 6 O atoms on both sides of the equation. It is important to ensure that the chemical equation is balanced, as only then will it tell you the relationship of the reactants and products in terms of mole.
Looking at the coefficients of Fe and Fe₂O₃, 4 moles of Fe is needed to make 2 moles of Fe₂O₃.
This can be simplified into the mole ratio below.
Fe: Fe₂O₃= 2: 1
This means that for every mole of Fe₂O₃, twice the amount of Fe (in moles) is needed.
Thus for 10 moles of Fe₂O₃,
amount of Fe needed
= 10 ×2
= 20 moles
Explanation:
Step one look for the longest chain of carbon atoms
Longest chain is 7 C atoms
Step 2 look for double bonds or others functional groups
it is present in 3rd carbon
Therefore IUPAC name is 3-heptene
From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.
Hope this helps...
Answer:
Option B is correct.
Another name for equilibrium price is **market-clearing price**
Explanation:
Equilibrium price is defined as the price at which the quantity of products/goods/services demanded is equal to/matches the quantity of products/goods/services supplied.
The equilibrium price is also called the market clearing price because, at this price, there is no supply leftover (surplus) or demand leftover (deficit). The market is literally cleared!
<span>Radioactive waste, as its name implies, is a source of radiation that can be harmful to living organisms. Therefore it needs to be disposed of very carefully in such a way that the radiation cannot reach human beings and other living organisms. One method to do this is to bury the waste in deep pits. </span>
