Answer:
1 When quicklime is added to water, it forms slaked lime along with the evolution of heat. There will be a rise in the temperature of the bucket. Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.
2: Examples of photochemical reactions
Photosynthesis: plants use solar energy to convert carbon dioxide and water into glucose and oxygen. Human formation of vitamin D by exposure to sunlight. Bioluminescence: e.g. In fireflies, an enzyme in the abdomen catalyzes a reaction that produced light.
3. balanced chemical equation has equal number of atoms of different elements in the reactants and products
4. This process is called corrosion. Rusting : Iron metal when left exposed, it reacts with moisture and air and get coated with reddish brown powdery substance called rust, this process is called rusting. Rancidity: Food containing fats and oil when exposed to air gets oxidised and gives bad taste and smell to food.
2:1. Hydrogen gas is produced when an active metal reacts with dilute hydrochloric acid, when a burning candle is brought near to hydrogen gas, a pop sound is heard due to the combustion of hydrogen gas to from water.
2. oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
3.
combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
