Answer:
The correct answer is - 4.
Explanation:
As we known and also given that the total of the superscripts that is mass numbers, A in the reactants and products must be the same.The mass of products A can understand and calculated by this -
The sum of the product mass number of products = mass of reactant
237Np93 →233 Pa91 +AZX is the equation,
Solution:
Mass of reactants = 237
Mass of products are - Pa =233 and A = ?
233 + A = 237
A = 237 - 233
A = 4
So the equation will be:
237Np93 →233 Pa91 +4He2 (atomic number Z = 2 ∵ difference in the atomic number of reactant and products)
. 1s2 2s2 2p6 3s2 3p6 3d10 One point is earned for the correct configuration.
Decreasing the activation energy needed for the reaction.
Answer:
protons
Explanation:
the number of protons in a nucleus are equal to the number of atoms in an element.
The answer is C.
While the Hydrogen atom symbol itself is labeled with 3, it is being multiplied by the coefficient of 3, giving us a total of 9 atoms.
