ME AJUDEM POR FAVOR !!!!!!! URGENTE !!!!!!!

Zn+2HCl → ZnCl2+H2.calcule: a massa de H2 produzido a partir de 6 mols de HCl.​

Answer 1

$\huge\boxed{\boxed{\mathsf{Zn+2HCl\to~ZnCl_{2}+H_{2}}}}$

$\mathsf{2g\,de\,H_{2}\to\,2mols\,de\,HCl}\\\mathsf{x~mols\,de\,H_{2}\to~6\,mols\,HCl}\\\huge\boxed{\boxed{\mathsf{x=\dfrac{2.6}{2}=6\,g\,de\,H_{2}}}}$
