Answer:
Explanation:
Given that
Mass ,m= 8.8 x 10¹³
Speed ,v= 33 km/s
We know that 1 km= 1000 m
v= 33 x 10³ m/s
As we know that kinetic energy given as
Now by putting the values in the above equation
Therefore we can say that the kinetic energy will be
The balanced equation for the above reaction is;
CH₄ + 2O₂ ---> CO₂ + 2H₂O
Stoichiometry of CH₄ to O₂ is 1:2
The number of methane moles present - 1.44 g/ 16 g/mol = 0.090 mol
Number of oxygen moles present - 9.5 g/ 32 g/mol = 0.30 mol
If methane is the limiting reagent,
0.090 moles of methane react with 0.090x 2 = 0.180 mol
only 0.180 mol of O₂ is required but 0.30 mol of O₂ has been provided therefore O₂ is in excess and CH₄ is the limiting reactant.
Number of moles of water that can be produced - 0.180 mol
Therefore mass of water produced - 0.180 x 18 g/mol = 3.24 g
Therefore mass of 3.24 g of water can be produced
The conclusion from these figures is that hydrogen should be produced at the cathode and oxygen at the anode from the electrolysis of water—which is at variance with the experimental observation that zinc metal is deposited and bromine is produce
C. Mitosis
Mitosis is a process where a single cell divides into two identical daughter cells.
The purpose of which is for growth and to replace worn out cells.
