Question

1.Qual a massa de CO 2 formada a partir de 14 gramas de CO? 2CO + O 2 → 2CO 2 ?

Answer 1

$\boxed{\begin{array}{l}\sf 2CO+O_2\longrightarrow 2CO_2\\\sf56~g~de~CO\longrightarrow98~g~de~CO_2\\\sf14~g~de~CO\longrightarrow x\\\sf 56x=1372\\\sf x=\dfrac{1372}{56}\\\\\sf x=24,5~g~de~CO_2\end{array}}$
