It is an alpha decay because when this phenomena occurs an atomic nucleus emits an alpha particle (helium nucleus) and consequentially decays into another atom with a mass number that is reduced by four an atomic number that is reduced by 2 two. The helium atom consists of two protons and two neutrons.
Therefore, the answer is <span>alpha decay because alpha particles have two protons and two neutrons</span>
C) They are not in a fixed position.

Answer:
0.7158 Mol/L
Explanation:
KHC8H4O4 + NaOH → H2O + KNaC8H4O4
KHC8H4O4 molar mass = 204.2212 g/mol
0.4536 g of KHC8H4O4 = 2.221 mMol (10^-3 mol)
volume = 31.26 mL - 0.23 mL = 31.03 mL
NaOH concentration = 2.221 mMol/31.03 mL = 2.221 Mol/31.03 L = 0.7158 Mol/L

Answer:
it remains the same
Explanation:
mass is like name is not changed any where mass express the amount of matter in an object which is fixed any where regardless its gravity
