What is a chemical equation that does not indicate relative amounts of reactants and products?
What is a chemical equation that does not indicate relative amounts of reactants and products?
Chapter 11 “Describing Chemical Reactions”
| A | B |
|---|---|
| skeleton equation | chemical equation that does not indicate the relative amounts of the reactants and products |
| products | the elements or compounds on the right side of a chemical equation after the arrow |
| (g) | designates a product or reactant that is in the gaseous state |
Do chemical equations describe chemical reactions?
A chemical reaction is described by a chemical equation, an expression that gives the identities and quantities of the substances involved in a reaction. A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow.
What is a concise representation of a chemical reaction?
chemical equation. a concise representation of a chemical reaction. balanced equation. an equation in which each side has the same number of atoms of each element. skeleton equation.
Which type of reaction is NaCl AgNO3 → NaNO3 AgCl?
double displacement reaction
What type of reaction is the generic equation a BC → AC B?
is a single displacement reaction. This type of reaction involves a free element reacting with a compound and replacing another element in the compound due to the fact that its more reactive than the element present in the compound. In the reaction above A displaces element B from compound BC.
How do you classify combination reactions?
Classify a chemical reaction as a synthesis, decomposition, single replacement, double replacement, or a combustion reaction….7.10: Classifying Chemical Reactions.
| Name of Reaction | General Form | Examples |
|---|---|---|
| Combination (Synthesis) | A + B → AB | CO2(g) + H2O(l) → H2CO3(aq) N2(g) + 2O2(g)→ 2NO2(g) |
| Decomposition | AB → A + B | CaCO3(s) → CaO(s) + CO2(g) |
What is the example of combination reaction?
When a combination reaction occurs between a metal and a non-metal the product is an ionic solid. An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide.
What is combination reaction give examples?
When two or more reactants combine with each other to form a new product it is called as combination reaction. Combination reaction is also known as synthesis reaction. For example hydrogen gets combined with chlorine to from hydro-chloride.
How many products are formed in a combination reaction?
A combination reaction is a reaction in which two reactants combine to form one product. Oxygen and the halogens are very reactive elements and are likely to undergo combination reactions with other elements.
What are 3 examples of decomposition reaction?
Decomposition Reaction Examples
- Carbonic acid in soft drinks decomposes to give carbon dioxide gas.
- Hydrogen gas and oxygen gas are released from the decomposition of water.
- Digestion of food is a decomposition reaction.
What is thermal decomposition give example?
Some compounds break down when heated, forming two or more products from one reactant. This type of reaction is called thermal decomposition . Copper carbonate is green and copper oxide is black.
