2022年12月22日 · 2NaNO3 + PbO → Pb(NO3)2 + Na2O Once the equation is balanced, you can use the coefficients in front of each compound to determine the mole ratio. In this case, the coefficient for PbO is 1, and the coefficient for Pb(NO3)2 is 1, which means that there is a 1:1 mole ratio between these two compounds.

2020年7月13日 · The balanced chemical equation 2NaNO3 --> 2NaNO2 O2 tells us that 2 moles of NaNO3 produces 1 mole of O2. Since the molar mass of O2 is 32 g/mol, 85*2 g of sodium **nitrate **will yield 32 g of O2. Therefore, to produce 128 g of O2, the mass of sodium nitrate required can be found using the ratio of mass of NaNO3 to mass of O2, or ( 85 ∗ 2/32 ...

2024年2月9日 · The student proposed the balanced chemical equation for the reaction between lead(II) nitrate and sodium iodide as Pb(NO3)2 + 2NaI → PbI2 + 2NaNO3. To determine if this is a correctly balanced equation, we can count the atoms of …
