How many moles of calcium oxide will be produced when 1.6 moles of Iron(III)oxide reacts with calcium phosphate according to the
koban [17]

Answer:


4.8 mol


Step-by-step explanation:


The balanced equation is


Fe₂O₃ + Ca₃(PO₄)₂ ⟶2FePO₄ + 3CaO


You want to convert moles of Fe₂O₃ to moles of CaO.


The molar ratio is 3 mol CaO:1 mol Fe₂O₃.


Moles of CaO = 1.6 mol Fe₂O₃ × (3 mol CaO/1 mol Fe₂O₃)


Moles of CaO = 4.8 mol CaO


The reaction will produce 4.8 mol of CaO.

2 Al + 3 H2SO4 --> Al2(SO4)3 + 3 H2 If you have 7.6 moles of Al, then how many moles of H2SO4 will be needed to react complet
Lelechka [254]

Answer:

11.4 moles of H₂SO₄ are needed to completely react the 7.6 moles of Al

Explanation:

The equation indicates that 2 moles of aluminum react to 3 moles of sulfuric acid in order to produce 1 mol of aluminum sulfate and 3 moles of hydrogen gas.

The reaction is:  2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂

This question can be solved with an easy rule of three. Ratio in the reaciton is 2:3, so we propose:

2 moles of Al react with 3 moles of sulfuric acid

Then, 7.6 moles of Al will react with 11.4 moles of H₂SO₄

The number of atoms present in 2.5 mole of triatomic gas is equivalent to ​
RUDIKE [14]

Answer: 1.41725 X 10^{24} atoms

Explanation:

One male of any gas containing no. of atoms$=6.023\times10^{23}$

2.5 moles of gas containing no. of atoms$=2.5\times6.023\times10^{23}$$=15.0575\times10^{23}$

The given gas is triatomic gas. Hence

No. of atoms$=3\times15.075\times10^{23}$

$=14.1725\times10^{23}$\\$=1.41725\times10^{24}$
