Systems in nature tend to undergo changes toward Lower energy and higher entropy.
the missing blank is filled by 11 O2
that is
= 2C4H6 + 11O2 = 8 CO2 + 6H2O
C4H6 reacted with oxygen (O2 )through the process of combustion to form carbon iv oxide (CO2) and water (H2O) . 11 infront of O2 is to make sure the molecules of O2 is balanced in both reactant side and the product side
Answer:
Shift in equilibrium position
Explanation:
The reddish-pink colour signalled the equivalence point. That is, pH=PKind. This was the point at which we have commonly the called the end point of the titration which has been carried out. As the solution was left to stand after this equivalence point was attained, the equilibrium position shifted again towards the acid side and the solution turned colourless once more. The equilibrium position indicated by the colour change depends on the H+ concentration of the solution.
Explanation:
The driving force behind plate tectonics is convection in the mantle. Hot material near the Earth's core rises, and colder mantle rock sinks.
Answer:
Every location on Earth experiences an average of 12 hours of light per day but the actual number of hours of daylight on any particular day of the year varies from place to place.
