I personally thinks it’s A
The molar mass is 294.1527 g/mol
Answer:
B
Explanation:
Bad conductor of elecricity
[Ar] 3d10 4s2 4p5 is the electron configuration of bromine
The CaCO3 produced if 47.5 moles of NH3 produced is calculated as follows
CaCN2 +3H2O = CaCO3 + 2NH3
by use of mole ratio between CaCO3 to NH3 which is 1:2 the moles of CaCO3 is therefore = 47.5 /2= 23.75 moles
mass of CaCO3 is therefore = moles x molar mass
= 23.75 moles x 100g/mol= 2375 grams which is approximate 2380 grams(answer 6)
