Jul 13, 2020 · 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 ...

Dec 22, 2022 · 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.

Jun 1, 2023 · The **balanced **chemical equation is:2NaNO3 + PbO → Pb(NO3)2 + Na2ONow, let’s write the balanced equation with their coefficients:2 moles of NaNO3 react with 1 mole of PbO to form 1 mole of Pb(NO3)2 and 1 mole of Na2O.Therefore, the mole ratio between lead(II) oxide and lead(II) nitrate is 1:1.

Jun 10, 2022 · Reaction: Na2CO3 + Ba(NO3)2 → BaCO3 + 2NaNO3. Analysis: Barium carbonate (BaCO3) is known to be insoluble in water and will form a precipitate in this double replacement reaction. Precipitate: BaCO3 (s) In summary, all three reactions lead to the formation of precipitates, which are as follows: CdS from the first reaction,

Oct 15, 2023 · In the chemical reaction represented by the equation Cu(NO3)2 + Na2CO3 → CuCO3 + 2NaNO3, we are tasked with identifying the spectator ions. Step 1: Understanding Spectator Ions Spectator ions are ions that exist in the same form on both the reactant and product sides of a chemical equation.

Pb(NO3)2+Na2CrO4 → PbCrO4+2NaNO3. Molar ratios in the reaction are ; 1 : 1 : 1 : 2. Which means; One mole of (Na2CrO4) produces two moles of (NaNO3) We can calculate the number of moles of Na2CrO4, Moles (na2CrO4) = 253g /162 = 1.56 moles . Moles of NaNO3 will be; = 1.56 moles x 2 = 3.12 moles

The chemical equation for the reaction is Na2S + 2AgNO3 → 2NaNO3 + Ag2S. The reaction involves the exchange of ions between the two compounds, with the sodium cation (Na+) and the silver cation (Ag+) switching places. The reaction is an important example of a double displacement reaction and is commonly used in the laboratory for various ...

Nov 7, 2023 · 2NaNO3 + CaCl2 → 2NaCl + Ca(NO3)2. On the left side of the equation, there are a total of 6 oxygen atoms from the two NaNO3 molecules. On the right side of the equation, there are also 6 oxygen atoms from the Ca(NO3)2 molecule. Therefore, there are 6 atoms of oxygen on each side of the equation.
