Name the Products & Reactants for:
Moving Car
Evaporating puddle
Electrolysis of water
Baking Soda mixed with vinegar
Not much to go on here. Are these 'real' questions or something to satisfy your curiosity?
gasoline==> CO2 + H2O
H2O(l) ==> H2O(g)
2H2O ==> 2H2 + O2
NaHCO3 + HC2H3O2 ==> NaC2H3O2 + CO2 + H2O
thxz and these are real questions from my unfair teacher
ok. Gasoline is a mixture of stuff but much of it is isooctane, which has C8H18 as the formula. I didn't know whether to write the formula or not.
The balanced equation is
2C8H18 + 25O2 ==> 16CO2 + 18H2O
To determine the products and reactants for each scenario, we can start by understanding the chemical reactions involved:
1. Moving Car:
In the case of a moving car, there are multiple reactions happening. The combustion of fuel, typically gasoline or diesel, powers the engine and is the primary reaction involved in its movement. The reactants in this reaction are the fuel (hydrocarbon) and oxygen from the air. The combustion reaction produces products such as carbon dioxide (CO2), water (H2O), and energy (in the form of heat and mechanical work) that enable the car to move.
Reactants: Fuel (hydrocarbon) and oxygen
Products: Carbon dioxide (CO2), water (H2O), and energy
2. Evaporating Puddle:
When a puddle evaporates, the water molecules in the liquid gain enough energy to overcome the forces of attraction between them, converting into vapor or gas state. This process is known as evaporation. The reactant in this scenario is the liquid water, and the product is the water vapor or gas.
Reactant: Liquid water
Product: Water vapor or gas
3. Electrolysis of Water:
During the electrolysis of water, an electric current is passed through water, leading to the breaking down of water molecules into its component elements. The reactants in this reaction are water (H2O) molecules, and the products are hydrogen gas (H2) and oxygen gas (O2). This is described by the following chemical equation:
2H2O (water) → 2H2 (hydrogen gas) + O2 (oxygen gas)
Reactant: Water (H2O)
Products: Hydrogen gas (H2) and oxygen gas (O2)
4. Baking Soda mixed with Vinegar:
When baking soda (sodium bicarbonate, NaHCO3) is mixed with vinegar (dilute acetic acid, CH3COOH), a chemical reaction occurs. Baking soda is a base, while vinegar is an acid. The reaction between an acid and a base is known as neutralization. In this reaction, the products formed are carbon dioxide gas (CO2), water (H2O), and a salt called sodium acetate (CH3COONa). The chemical equation representing this reaction is as follows:
NaHCO3 (sodium bicarbonate) + CH3COOH (acetic acid) → CO2 (carbon dioxide gas) + H2O (water) + CH3COONa (sodium acetate)
Reactants: Sodium bicarbonate (NaHCO3) and acetic acid (CH3COOH)
Products: Carbon dioxide gas (CO2), water (H2O), and sodium acetate (CH3COONa)
Understanding the reactants and products involved in various chemical reactions helps us gain knowledge about the chemistry behind different phenomena.
