The reaction is low b/c of the tempature. that's why.
0.0024 g of Ba(NO₃)₂
Explanation:
First we need to determine the molecular weight of barium nitrate Ba(NO₃)₂
molecular wight of Ba(NO₃)₂ = molecular weight of Ba × number of Ba atoms + molecular weight of N × number of N atoms + molecular weight of O × number of O atoms
molecular wight of Ba(NO₃)₂ = 137 × 1 + 14 × 2 + 16 × 6 = 261 g/mol
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Ba(NO₃)₂ = 0.625 / 261 = 0.0024 g

Neutrons = mass no. - atomic no. Therefore depending on your periodic table (mine says 12 for mass number) so you do (mass no. - 6 = 6 or 7 ) depending again if you use 12 or 13
Chemical energy starts when you eat or drink something bc when you eat or drink something the energy of that food or drink goes into ur muscle.Mechanical occurs when you move ur muscle like when you kick a ball its mechanical.Thermal happens when ur hot or sweating
