When chlorine gas is bubbled into a solution of sodium bromide, the sodium bromide reacts to give bromine , a red-brown liquid, and sodium chloride (ordinary table salt).
What kind of chemical reaction does the chemical equation sodium chlorine → sodium chloride represent quizlet?
An example of a synthesis reaction is the combination of sodium and chlorine to produce sodium chloride.
Which type of chemical reaction occurs in CA Cl2 CaCl2 quizlet?
Which type of chemical reaction occurs in Ca + Cl2 → CaCl2? Which reaction will occur? Sodium chloride reacts with copper sulfate to produce sodium sulfate and copper chloride. double replacement reaction .
Why does mass increase when sodium reacts with chlorine?
The sodium loses an electron, and the chlorine gains that electron . This reaction is highly favorable because of the electrostatic attraction between the particles.
What does an arrow mean in a chemical equation?
The chemical reaction arrow is one straight arrow pointing from reactant (s) to product(s) and by-products , sometimes along with side products. ... The single arrow emphasizes one direction of chemical change (from A to B).
Which chemical reaction involves the production of a gas quizlet?
1. A combustion reaction involves oxygen gas and oftentimes produces water and carbon dioxide. They release energy as a product in the form of heat or light.
Which type of chemical reaction is the following an example of c6h12 9o2 → 6co2 6h2o?
Explanation: Balanced chemical reaction : C6H12 + 9O2 → 6CO2 + 6H2O. 1) Synthesis is reaction of two or more substances combining to make a more complex substance.
Which chemical equation is unbalanced?
If the numbers of each type of atom are different on the two sides of a chemical equation, then the equation is unbalanced, and it cannot correctly describe what happens during the reaction.
How do you separate sodium and chlorine?
By electrolysis , common salt, sodium chloride, NaCl, can be broken down into its elements, sodium and chlorine. This is an important method for the production of sodium; it is used also for producing other alkali metals and alkaline earth metals from their salts.
Does sodium react with chlorine?
The heat from the reaction of water with sodium gets the sodium hot enough to react with the chlorine. The hot sodium reacts with the chlorine gas, burning with a bright yellow flame.
What is the meaning of an arrow pointing upward in a chemical equation?
An arrow pointing up (as in CO2?) indicates that the product will form a gas that will bubble out of a solution. ... indicates that the product will spontaneously precipitate from the solution . (“Precipitate,” in this sense, means the formation of a solid from the combination of two aqueous solutions.)
Why can’t you change the formula in order to balance a reaction?
Balancing a Chemical Equation. Because the identities of the reactants and products are fixed , the equation cannot be balanced by changing the subscripts of the reactants or the products.
What chemical reaction involves the production of a gas?
Many reactions produce a gas such as carbon dioxide, hydrogen sulfide, ammonia, or sulfur dioxide. Cake batter rising is caused by a gas-forming reaction between an acid and baking soda (sodium hydrogen carbonate).
How is gas produced in a chemical reaction?
The formation of a gas is the third sign that a reaction may have occurred. The formation of bubbles when two liquids are mixed usually indicates that a gas has formed. A gas can also be formed when a solid is added to a solution. Continue on to the next sign.
