HOW H2SIF6 is form?
H2SIF6, or hydrogen hexafluorosilicate, is formed through the reaction of silicon dioxide (SiO2) with hydrofluoric acid (HF). This reaction typically occurs when silica is treated with an excess of HF, leading to the generation of hexafluorosilicate ions (SiF6²⁻) in solution, which can then combine with hydrogen ions (H⁺) to produce H2SIF6. This compound is often encountered in industrial processes involving fluorosilicate salts or as a byproduct in the production of silicon.
What is a fixed proportion?
A fixed proportion refers to a constant ratio between two or more variables, meaning that as one variable changes, the other(s) change in a predictable, consistent manner. This concept is often used in mathematics, economics, and chemistry to describe relationships where the components maintain a specific ratio regardless of their individual quantities. For example, in a chemical reaction, a fixed proportion can indicate the exact amounts of reactants needed to produce a certain product without excess.
What is excess in math?
In mathematics, "excess" typically refers to the amount by which a quantity exceeds a specified limit or value. For example, if a budget allows for $100 but a person spends $120, the excess spending is $20. In other contexts, such as geometry, "excess" can also describe the amount by which a figure surpasses a certain measure, like the excess angle in spherical geometry, where it exceeds the sum of angles in Euclidean space.

How many milliliters of 0.200 M FeCl3 are needed to react with an excess of Na2S to produce 0.690 g of Fe2S3 if the percent yield for the reaction is 65.0 3 Na2S(aq) plus 2 FeCl3(aq) Fe2S3(s) plus?
To find the moles of Fe2S3 produced, convert 0.690 g to moles using the molar mass of Fe2S3. Then, use the stoichiometry of the reaction to determine the moles of FeCl3 required. Finally, use the molarity of FeCl3 to calculate the volume in milliliters needed, keeping in mind the percent yield.

How many moles of Co2 will be produced from the reaction of three moles of acetylene with excess oxygen?
Since acetylene (C2H2) has a stoichiometry of 2 moles of acetylene to produce 2 moles of CO2, three moles of acetylene would produce 3 moles of CO2. The reaction with excess oxygen ensures that all the acetylene is fully converted to CO2.

How do you determine the limiting agent and excess?
The limiting agent in a chemical reaction is the reactant that is completely consumed first, stopping the reaction. To determine the limiting agent, calculate the amount of product each reactant can produce and identify the one that produces the least amount of product. The other reactant is then in excess.
