Hydrofluoric acid (hf) is used to etch glass (sio2). the products of the reaction are silicon tetrafluoride and water. write the
2 answers:
<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.
When hydrofluoric acid reacts with glass or silicon dioxide, it leads to the production of silicon tetrafluoride and water.
The chemical equation for the reaction of two follows:
By Stoichiometry of the reaction:
4 moles of hydrofluoric acid reacts with 1 mole of silicon dioxide to produce 1 mole of silicon tetrafluoride and 2 mole of water.
Hence, the balanced chemical equation is written above.

Based on the information given regarding the energy, the true statement is C. "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
<h3>What is energy?</h3>It should be noted that energy is the quantitative property that must be transferred to a body to perform work on the body.
In this case, the graph is shown with two inverted graph curves running close to each other, and one of the curves labeled T1 is slightly more spread out than the other labeled T2.
Here, T1 is the only sample with a particle able to react. Particle B is more likely to participate in the reaction than particle A and the number of particles able to undergo a chemical reaction is less than the number that is not able to.
