A incline plane is a flat inclined surface. You can stick a rope in the pulley and pull one side and the other side will lift something! They are both simple machines! The difference is a incline plane is a ramp and things go up or down and the pulley lifts something with force of your weight!!
P₄0₆
+ 20₂
⇒ P₄0₁₀
Explanation:
The overall equation for the reaction that produces P₄0₁₀ is :
P₄0₆ + 20₂ ⇒ P₄0₁₀
Now let us derive this equation:
Given equations:
P₄ + 30₂ ⇒ P₄0₆ equation 1;
P₄ + 50₂ ⇒ P₄0₁₀ equation 2;
To get the overall combined equation, the equation 1 must be reversed and added to equation 2:
P₄0₆ ⇒ P₄ + 30₂ equation 3
+
equation 2:
P₄ + 50₂ + P₄0₆ ⇒ P₄0₁₀ + P₄ + 30₂
cancelling specie that appears on both sides and removing excess oxygen gas on the reactant side gives;
P₄0₆ + 20₂ ⇒ P₄0₁₀

A. the number of protons in the atoms
Answer:
The answer to your question is:
a) 0.069 moles of Iron
b) 0.052 moles of Oxygen
Explanation:
Data
mass Iron = 3.86 g
moles = ?
Atomic weight Fe = 56 g
Process
a) Solve it using a rule of three
56 g of Fe ---------------- 1 mol
3.86 g ---------------------- x
x = (3.86 x 1) / 56
x = 0.069 moles of Iron
b)
Balanced Equation
4Fe + 3O₂ ⇒ 2Fe₂O₃
Solve it using a rule of three
4 moles of Fe ----------------- 3 moles of O₂
0.069 moles of Fe --------- x
x = (0.069 x 3) / 4
x = 0.052 moles of Oxygen
