Write a balanced equation for the reaction that occurs in each of the following cases: (a) White phorphrous, P 4 (s), reacts with chlorine gas. (b) Sodium metal reacts with water. (c) Sulfur reacts with hydrogen gas.

Hi everyone here we have a question asking us to identify the balanced chemical reaction between the following compounds, hydrogen iodide gas and bromine gas. So we have hydrogen iodide gas plus browning gas, which is a di atomic element. So B. R two gas and it is going to displace iodine in the hydrogen iodide. So we're going to have hydrogen with a plus one charge and bro mean With a -1 charge. So they are going to come together and these are going to cancel out giving us hydrogen bromine bromide. So that's going to form a hydrogen bromide plus iodine, which is a di atomic element. So I too. And now we want to balance this. So if we look on the left we see that we have to be roaming and on the right we only have one. So we need to put a two in front of our hydrogen bromide and if we look on our product side we have two iodine and we only have one on our reactant side. So we need to put a two in front of our hydrogen iodide and now we have two hydrogen iodide gasses Plus bro. Mean gasses forms two hydrogen bromide gashes, plus iodine gashes and that is our final balanced chemical equation. Thank you for watching. Bye.

Problem 77a,b,c

Chapter 7, Problem 77a,b,c

Write a balanced equation for the reaction that occurs in each of the following cases: (a) White phorphrous, P₄(s), reacts with chlorine gas. (b) Sodium metal reacts with water. (c) Sulfur reacts with hydrogen gas.

Verified step by step guidance

Identify the reactants: sulfur (S) and hydrogen gas (H₂).

Determine the product: sulfur reacts with hydrogen to form hydrogen sulfide (H₂S).

Write the unbalanced chemical equation: S + H₂ → H₂S.

Count the number of each type of atom on both sides of the equation to ensure they are equal.

Balance the equation by adjusting coefficients: S + H₂ → H₂S is already balanced as there is one sulfur atom and two hydrogen atoms on each side.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Chemical Reactions

A chemical reaction involves the transformation of reactants into products through the breaking and forming of chemical bonds. In this case, sulfur and hydrogen gas will react to form a new compound. Understanding the types of reactions, such as synthesis, decomposition, or combustion, is essential for predicting the products formed.

Balancing Chemical Equations

Balancing a chemical equation ensures that the number of atoms for each element is the same on both sides of the equation, adhering to the law of conservation of mass. This process involves adjusting coefficients in front of the chemical formulas to achieve balance, which is crucial for accurately representing the reaction.

Formation of Hydrogen Sulfide

When sulfur reacts with hydrogen gas, the primary product formed is hydrogen sulfide (H2S). This compound is a colorless gas with a characteristic odor of rotten eggs. Recognizing the products of specific reactants helps in writing the correct balanced equation for the reaction.
