For each solution, write the chemical formulas of the major species present atequilibrium. You can leave out water itself.Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and theformulas of the species that will act as neither acids nor bases in the 'other' row.You will find it useful to keep in mind that NH3 is a weak base.Juliannaacids:0.4 mol of HNO3 is added to1.0 L of a 0.8M NH3bases:solution.☐ other: ☐0.1 mol of NaOH is added to1.0 L of a solution that is0.3M in both NH3 andNH,C1.☐ acids: ☐bases:other:ExplanationCheckод....MacBook Airolo2024 McGraw Hill LLC.

O CHEMICAL REACTIONS Limiting reactants QU N OO EXPLANATION Gaseous butane (CH₂(CH₂)₂CH3) will react with gaseous oxygen (O₂) to produce gaseous carbon dioxide (CO₂) and gaseous water (H₂O). Suppose 2.3 g of butane is mixed with 4.49 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 3 significant digits. The question is a limiting reactant problem. You can tell it's a limiting reactant problem by the fact that you were given the initial amounts of more than one reactant. Here is the balanced chemical equation for the reaction you will need to solve the problem: 2 CH₂ (CH₂), CH₂(g) + 130₂ (g) → 8 CO₂(g) + 10 H₂O(g) You can solve limiting reactant problems in the following three steps: Step 1: Find the initial…

What should be done to the liquid to finish the separation? O Heat the mixture to evaporate the liquid O Add a base to neutralize the solution. O Nothing - you are done since you have a pure, clear, colorless substance O Add the residue back to the solution and dry. QUESTION 4 In Part II of experiment 5, a 1:1:1 mixture of sand, salt, and salicylic acid must be separated. Order the following steps necessary to separate this mixture into three pure, dry solids. Filter the liquid leaving a filtrate with just salt dissolved and a residue of sand. v Add hot water to the residue obtained in two steps prior to this one.
