What gets written into a chemical reaction when it is balanced?
In a complete and correctly balanced chemical equation you will have the coefficients for each reactant and product indicating the mole ratios as well as the phases of each reactant and product.
What happens to energy during a chemical reaction?
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
When two chemicals are mixed and the breaker gets warm it usually indicates that a chemical reaction has taken true or false?
true
What chemical reaction takes place when bleaching a stain?
Bleaching stains typically involves the chemical reaction of the bleach (usually chlorine-based compounds like sodium hypochlorite) breaking down the chromophores in the stain molecules. This process disrupts the bonds that give the stains their color, effectively decolorizing them.
When writing a chemical formula the (what type of ion) gets written first.?
Cations are written first. For instance, NaCl or H2O.
What gets written into a chemical reaction when it is balanced?
In a complete and correctly balanced chemical equation you will have the coefficients for each reactant and product indicating the mole ratios as well as the phases of each reactant and product.
What is the balanced chemical equation for the reaction of nitrogen oxide with water?
The balanced chemical equation for the reaction of nitrogen oxide (NO) with water (H2O) is: 2NO + H2O → HNO2 + HNO3.
Differentiate between the reactants and the products in the reaction?
Reactants are the starting materials in a chemical reaction that come together to form the products. Products, on the other hand, are the substances that are formed as a result of the reaction. In a chemical equation, reactants are usually written on the left side and products on the right side.
What triggers the chemical reaction and gets it going or photosynthesis?
Sunlight - uv
What happens during a chemical reaction that involves an acid and a base?
it gets a liquid out
What is difference between released chemical energy and absorbed chemical energy?
When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction. When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.
When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
What is an element or compound that enters into a chemical reaction?
A reactant is a substance that enters into a chemical reaction and is transformed into a new product. It is present at the start of the reaction and gets consumed during the process.
How does a fire start?
when a flammable chemical such as oil (ancient tree) gets heated up to much it acts as a chemical reaction it catches on fire
What happen when mix baking soda and vinegar?
it gets messy and fizzes and yes dont try it in doors
What is Potassium iodide bromine reaction?
The reaction between potassium iodide and bromine forms potassium bromide and iodine. It is a redox reaction, where bromine gets reduced from 0 to -1 and iodide gets oxidized from -1 to 0. The reaction is represented by the following equation: 2KI + Br2 -> 2KBr + I2.
What happens to energy during a chemical reaction?
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
