Pt195 having 78 atomic number is the daughter nucleus produced when Au195 undergoes electron capture.
An unstable isotopes can undergoes radioactive decay to form a more stable isotopes . Initial isotopes is called parent nuclide and the resultant isotopes from radioactive decay is called the daughter nuclide There are several radioactive decay like alpha decay , beta decay , gamma decay , electron capture etc .
In electron capture , the atom have only one less which is daughter isotopes than electron than atomic number of parent isotopes.

Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 2 moles of 
Thus 0.06 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 moles of give = 1 mole of 
Thus 0.06 moles of give =
of
Mass of 
Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.
The answer is A it’s tall
Answer:
KCl ⇒ 1.205x10²⁴ molecules
O₂ ⇒ 1.807x10²⁴ molecules
KClO₃ ⇒ 1.205x10²⁴ molecules
Explanation:
In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states <em>the number of particles in one mol</em>:
- In 1 mol there are 6.023x10²³ particles (ions, molecules or atoms).
So now we <u>multiply the number of moles of each substance by Avogadro's number</u>:
- KCl ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules
- O₂ ⇒ 3 mol * 6.023x10²³ molecules/mol = 1.807x10²⁴ molecules
- KClO₃ ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules
Answer:
reflection
