Which kind of reaction is shown below?
2h2o2 → 2h2o + o2
synthesis reaction
decomposition reaction
single replacement reaction
double replacement reaction

decomposition reaction

Explanation:-

1. Synthesis is a type of chemical reaction in which two or more than two reactants combine together to give a single product.

2. Decomposition is a type of chemical reaction in which a single reactant gives two or more than two products.

3. Single replacement is a type of chemical reaction in which a more reactive element displaces the less reactive element from its slat solution.

4. Double replacement is a type of chemical reaction in which exchange of ions take place.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
