If a substance is very stable it will take a lot to break it down. If it's unstable it will break down very easy and fast.
Answer:
Mercury fulminate is very sensitive to shock, friction, and sparks. ... put mercury fulminate into blasting caps for detonating dynamite.
Explanation:
11 lb = 4.99 kg.
So, 74.85 mg should be given to the infant. Thus 0.75 mL of the suspension should be given.
Fe2O3 + 2Al ---> Al2O3 + 2Fe
Mole ratio Fe2O3 : Al = 1:2
No. of moles of Fe2O3 = Mass/RMM = 250 / (55.8 * 2 + 16 * 3) = 1.56641604 moles
No. of moles of Al = 150/27 = 5.555555555 moles.
Mole ratio 1 : 2. 1.56641604 * 2 = 3.13283208 moles of Al, but you have 5.555555555 moles of Al. So Al is in excess. All of it won't react.
So take the Fe2O3 and Fe ratio to calculate the mass of iron metal that can be prepared.
RMM of Fe2O3 / Mass of Fe2O3 = RMM of 2Fe / Mass of Fe 159.6 / 250 = 111.6 / x x = 174.8 g of Fe
