Mendel's laws of hereditary are
1) Segregation
2) Independence
3) Dominance
Since you putting them from third to first, your
answer would be A. Dominance, Independence, Segregation.
Bromine, it's the only element that isn't a metal
answer
2500
because it's mm
and you just have to add 2 more place values
The energy change if 84.0 g of CaO react with excess water is 98KJ of heat is released.
calculation
heat = number of moles x delta H
delta H = - 65.2 Kj/mol
first find the number of moles of CaO reacted
moles = mass/molar mass
the molar mass of CaO = 40 + 16= 56 g/mol
mass = 84 g
moles therefore = 84 g/56 g/mol =1.5 moles
Heat is therefore = 1.5 moles x -65.2 = - 97.8 Kj = -98 Kj
since sign is negative the energy is released
