Which type of reaction would result in the products of water and carbon dioxide?
Combustion Reaction of light and heat. For organic compounds, such as hydrocarbons, the products of the combustion reaction are carbon dioxide and water.
What is the word equation for sodium chloride?
NaCl
Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions….CHEBI:26710 – sodium chloride.
| ChEBI Name | sodium chloride |
|---|---|
| Definition | An inorganic chloride salt having sodium(1+) as the counterion. |
What is the reaction between sodium chloride and water?
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
What is the word equation for the reaction of sodium with water?
sodium + water → sodium hydroxide + hydrogen.
What happens when carbon dioxide in exhaled air mixed with water?
When carbon dioxide reacts with water a weak acid is formed. Carbon dioxide present in exhaled air is blown into a flask containing an indicator sensitive to small changes of pH in the appropriate region of the pH scale, and the consequent colour changes observed and recorded.
What is the reaction between co2 and H2O?
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.
What is word equation of a reaction?
A word equation represents a chemical reaction using the names of the substances involved. Word equations do not show any chemical symbols or formulae.
What type of reaction is sodium chloride?
synthesis reaction
A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).
What type of chemical reaction is sodium chloride?
A reaction of sodium with chlorine to produce sodium chloride is an example of a combination reaction. The physical states of reactants and products are included where necessary. The symbols used are: ( s ) for solid, ( l ) for liquid, ( g ) for gas, and ( aq ) for aqueous (water) solutions.
When sodium chloride and metallic sodium are each dissolved in water what happens?
When small quantities of sodium metal is added to water, there is an exothermic reaction, and they react to form sodium hydroxide and hydrogen.
What is the product of sodium and water?
sodium hydroxide
In what way and in what form does sodium react with water? A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction. Sodium metal is heated and may ignite and burn with a characteristic orange flame.
What are the products of a word equation?
Products can be elements or compounds. A word equation is a short-hand way of describing a chemical reaction. reactant(s) → product(s) A word equation shows the names of the reactants on the left hand side. If more than one reactant is present then the names of each reactant are separated by a plus sign (+).
How do you write a word equation to represent a chemical reaction?
In order to write a word equation to represent a chemical reaction I must: write the name of the product (sugars) to the right of the arrow So my word equation for the breakdown of starch into sugars in my mouth is: A reactant could break down to produce more than one new substance, that is, more than one product.
What is meant by balancing the chemical equation for a reaction?
In other words, there must be the same number of each type of atom on the product side as on the reactant side of the arrow. This is called BALANCING THE CHEMICAL EQUATION for the reaction. When balancing an equation the identities (formulas) of the compounds must never be changed.
How do you write a decomposition reaction?
Decomposition reactions will begin with a single reactant and end with two products. Example: AB -> A + B Write a balanced chemical equation for each decomposition reaction. a. Ag2O (s)->? b. NH4NO3-> N2O + 2H2O Use the activity series of metals to write a balanced chemical equation for each single-replacement reaction. a. Au (s) + KNO3 (aq) → b.
