Answer:
they represent their own atoms
Melting can always be changed back. Also remember that a physical change is a change of state. When you melt you go from a solid to a liquid. Flammability is a chemical property because you burn it.
Answer:
The yield is 16 moles of CO2 per 2 moles of isooctane.
The mass of CO2 is 1.15 billion tonnes
Explanation:
First we set the unbalanced equation:
Now we proceed to balance the equation:
With the equation balanced, we see that the theoretical yield is 16 moles of CO2 per 2 moles of isooctane and we can proceed to make calculations with the following data:
Knowing the different relations between mass, density and molar mass, we have the following results:
Answer:
seed plants with flowers
