Question

sabendo se que os dois elementos quimicos 3x+5, 2x+2 e 6x-10, x+9 sao isobaros, calcule o numero de nêutrons de A​

Answer 1

$_{2x+2}A^{3x+5}\\_{x+9}B^{6x-10}$

$\mathsf{3x+5=6x-10}\\\mathsf{6x-3x=5+10}\\\mathsf{3x=15}\\\mathsf{x=\dfrac{15}{3}=5}$

$_{2.5+2}A^{3.5+5}\\_{12}A^{20}$

$\boxed{\boxed{\mathsf{n_{A}=20-12=8}}}$
