Answer:
Mitochondria are the structures within cells that produce energy.
Explanation:
Mitochondria are also like the human digestive system because the digestive system breaks down food to supply the body with energy like the mitochondria breaks down food to supply the cell with energy.
Answer:
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
Answer:
21.2 moles.
Explanation:
Hello!
In this case, for the given chemical reaction, we can see there is a 1:4 mole ratio between tetraphosphorous decaoxide and phosphorous; therefore, the following proportional factor provides the requested moles of phodphorous:

4, 5, 4, 6 is how to balance the equation
Answer:0.86
Explanation:
A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5922 atm when placed in a sealed container.Lets suppose initially partial pressure of CH4 is x and C5H12 is y
x+y=0.5922-----i
1.CH4[g] + 2O2[g] -> CO2[g] + 2 H2O[g]
2.C5H12 + 8O2 → 5CO2 + 6H2O
partial pressure of CH4 is x produce xatm of CO2 and 2xatm of H2O
x + 2x = 3 atm
partial pressure of C5H12 is y produce 5yatm of CO2 and 6yatm of H2O
5y+6y=11y
so the final partial pressure of product mixture will be
3x + 11y = 2.429atm ------ii
solve eq i for x and put in ii
x=0.5922-y -----iii
3(0.5922-y)+ 11y = 2.429atm
y= 0.8155atm
put in iii
x=0.5922-0.8155
x= 0.51atm (Partial pressure of CH4)
mol fraction of CH4=Partial pressure/
Total pressure
=0.51/0.5922
=0.86.
