Answer: 3.5 moles
Explanation:
For every 2 moles of sulfur consumed, there are 3 moles of oxygen consumed.
This means that sulfur is the limiting reactant, meaning that 2(3)=6 moles of oxygen will be consumed.
Thus, 9.5-6=3.5 moles of oxygen will remain.
The answer is: Objects in the universe attract each other through gravitational force, depending on their masses and distance between the objects. I took a quiz with that question and got it right. Hope it helps :)
Answer:
Specific heat capacity formula
Explanation:
The heat capacity gives the exact heat energy at which a given mass of a substance is heated from one temperature to another.
This formula can help determine how much heat is gained or lost during the reaction and is given by:
Q = mcΔT
where:
Q = heat energy in Joules or Calories
m - mass of the substance (g)
c = Specific heat capacity (J/kg°C)
ΔT = change in temperature = (final temp - initial temp) (°C)
I hope this was helpful.
Molar mass :
O2 = 31.99 g/mol
C5H12 = 72.14 g/mol
<span>C5H12 + 8 O2 = 5 CO2 + 6 H2O
</span>
74.14 g ----------------- 8 x 31.99 g
18 g -------------------- ? ( mass of O2)
18 x 8 x 31.99 / 74.14 =
4606.56 / 74.14 => 62.133 g of O2
hope this helps!
Answer:
3Fe2O2---> Fe3O4
Explanation:
You need to add three to the left side to make it equal to the one on the right, and add a 2 since you can't change the subscripts
