15.0 cm3 of 1.0 mol/dm-3 (0.945g) HNO3 are reacted with 8.0 grams of CaCO­­3. Identify the limiting reactant and determine the theoretical yield of CO2 in dm3. HNO3(aq) + CaCO3(s) → Ca(NO3)2 (aq) + H2O(l) + CO2(g)

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
