Explanation:
Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

1.5 moles of gas
Reaction of Al with to form is given below...
2 Al + 1.5 →
Here, 2 moles of Aluminum reacts with 1.5 moles of
atomic weight of aluminum = 27 g / mole
so, 1 mole of aluminum contains 27 g
then how many moles are there if it has 54 g in it.
moles of aluminum in 54 g = 54/27 = 2 moles
As per the equation mentioned above,
2 moles of aluminum reacts with 1.5 moles of .
∴1.5 moles of oxygen gas (02) are needed to completely react with 54.0 g of aluminum.

2.00 M NaOH means that there are 2 moles of NaOH in each liter of solution
First, find how many moles of NaOH we have. Use this equation.
Molarity x Liters = Moles
Convert mL to L
7.58 mL x 1 Liter/1000mL = .00758 L
Set up the equation
2.00 M x .00758 L = .01516 moles
The molar mass of NaOH is 39.997 g
.01516 moles x 39.997 grams per mole = .60635452 rounded with significant figures to .606 grams of NaOH
Answer:
A. 3 moles of C will be produced from 1 mole of A
B. 4 moles of D will be produced from 4 moles of A
Explanation:
The balanced equation of the reaction between the three species A, C and D has been given in the question as -
A → 3C + D
According to the coefficients of the above reaction, we can draw the following conclusions -
- 1 mole of A can produce 3 moles of C
- 1 mole of A can produce 1 mole of D
Thus, as asked in the question,
If we are taking 1 mole of A then moles of C that will be produced = 3 moles
Again,
If we take 4 moles of A, then moles of D that will be produced = 4 moles.
