If I have a bag of iron oxide(lll) and powdered aluminium in the ratio of 3:1 totalling 72g, with 54g being Fe2O3 and 18g of 2Al, what would the temperature be when it burns during the exothermic reaction? Can you provide full working out please?
Thank you very much
P.S the powder would be mixed and put in a plant pot.
2)calculate the mean speed of a molecule of methane gas at 27°c.
3) Determine the excluded volume of a gas whose molecular radius is 2.9×10^-8cm

time t. if U(rel)-> is the velocity of the
exhaust with respect to the rocket show that
V-> -V0->=U(rel)->ln(m/m0)- g->t where g-> is the acceleration due to gravity.
Here V0->and M0 are the respective initial values of the velocity and mass. Would this
equation have been valid if g-> had simply been written as g? Explain your answer.

The distance between the two is 1000 times
the radius of the star. calculate the location of
the centre of mass of the system. State whether it is inside the star or outside it.
