reactants, particles and atoms
a) 2mg + ticl₄ ⟶ 2mgcl₂ + ti
b) 1.02 kg
a) balanced equation
we know we will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.
m_r: 24.30 47.87
2mg + ticl₄ ⟶ 2mgcl₂ + ti
b) mass of mg
(i) calculate the moles of ti
n = 1.00 kg ti × (1 kmol ti /47.87 kg ti)
= 0.020 89 kmol ti
(ii) calculate the moles of mg
the molar ratio is (2 kmol mg/1 kmol ti)
n = 0.020 89 kmol ti × (2 kmol mg/1 kmol ti)
= 0.041 78 kmol mg
(iii) calculate the mass of mg
m = 0.041 78 kmol mg × (24.30 kg mg/1 kmol mg)
= 1.02 kg mg
you need 1.02 kg mg to produce 1.00 kg ti.
the reactions are
in this reaction the bismuth gives an alpha particle and followed by beta decay
in this reaction the bismuth is undergoing beta bombardment followed by alpha decay.
this is not a reaction of bismuth.
this is first beta elimination followed by alpha elimination.
sodium azide is a colorless inorganic salt that can decompose to give sodium and nitrogen. it is an ionic compound and it is very soluble in water, but it is very toxic. the decomposition reaction usually take place at a very high temperature of 300 degree celsius under controlled conditions. the equation for the chemical reaction is given below:
2nan3 = 3n2 + 2na
