\(n_{CaCO_3}=\dfrac{10}{100}=0.1\left(mol\right)\)
\(n_{HCl}=\dfrac{3.65}{36.5}=0.1\left(mol\right)\)
\(CaCO_3+2HCl\rightarrow CaCl_2+CO_2+H_2O\)
\(1..................2\)
\(0.1..............0.1\)
\(LTL:\dfrac{0.1}{1}>\dfrac{0.1}{2}\Rightarrow CaCO_3dư\)
\(m_{CaCO_3\left(dư\right)}=\left(0.1-0.05\right)\cdot100=5\left(g\right)\)
\(V_{CO_2}=0.05\cdot22.4=1.12\left(l\right)\)
Để phản ứng xảy ra vừa đủ :
\(n_{CaCO_3\left(dư\right)}=\dfrac{5}{100}=0.05\left(mol\right)\)
\(n_{HCl}=2\cdot0.05=0.1\left(mol\right)\)
\(m_{HCl\left(ct\right)}=0.1\cdot36.5=3.65\left(g\right)\)
