<span>Answer is: atomic number
of resulting atom is 88.
Alpha particle is nucleus of a helium-4 atom, which is made of
two protons and two neutrons.
Nuclear reaction: ²³</span>²Th → ²²⁸Ra + α (alpha
particle).
Alpha
decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
Isotopes= a group of atoms with the same no. of protons , but different no. of neutrons
Hydrogen isotopes
The name of the second isotope is deuterium and the name of the third isotope is tritium(radioactive).The most abundant isotope is
Answer: The forces of attraction are stronger in new attractions that are formed.
Explanation:
When a chemical reaction takes place between two or more different compounds then less reactive substance is displaced by the more reactive substance.
During this process, when bonds are broken between the reactants then it means the force of attraction is less stronger. The formation of new compounds occur because force of attraction is more in these new substances due to which its atoms come closer to each other.
Thus, we can conclude that forces of attraction are stronger in new attractions that are formed.
<span>CO is the limiting reactant
( 25.0 x 3 = 75 moles of CO are required)
Moles Fe = 30.0 x 2 / 3 = 20.0
mass Fe = 20.0 x 55.847 g/mol=1117 g </span><span>
