What about? You must provide a question :)
1. to save space as less goes to landfill
2. acidic soil as OH is alkali
3. nitrates (ammonia is nitrogen and hydrogen)
4. I don't know this one sorry
5. CaCO3 is limestone and when it is heated its called thermal decomposition
1) State the equation that represents the chemical reaction
P2O5 + 3H2O → 2H3PO4
2) State the molar ratios: 1 mol P2O5 : 3 mol H2O : 2 mol H3PO4
3) Use the proportions 3molH2O / 2 mol H3PO4
0.729 mol H3PO4 * [ 3 mol H2O / 2 mol H3PO4] = 1.094 mol H2O
Answer: 1.094 mol of water
Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.
