what are the names of Sonic the Hedgehogs father, uncle, mother, and dog?

Answer 1

Q1- Synthesis reactions consist of combining two reactants to form one product. The only possible answer would be alternative B), in which A+B (the reactants) produce AB (the product).

Q2- Redox reactions are related to reduction and oxidation reactions that happen at the same time. On reduction, the atom involved gains more electrons and on oxidation, the atom loses electrons. Having in mind that both are happening simultaneously, alternative C) would be the correct answer.

Q3- A single replacement reaction is a reaction in which one atom that is part of a molecule is exchanged for another atom, resulting in a different product. The other atom that replaced the former one works as a reactant at the begining, together with the molecule in which the replacement takes place.

Ex: AB + C -> AC + B

His father is Jules Hedgehog, his mother is Queen Aleena , his uncle is Professor Charles the Hedgehog and his dog is Muttski.

Answer 2

Answer: -

1) A synthesis reaction is one in which two or more reactants combine together to form a single product.

In option B, we can see that two reactants A and B are reacting together to give AB, a single product.

So A+B->AB is an example of synthesis reaction.

2) Redox reaction stands for reduction oxidation reaction i.e. a reaction where both reduction and oxidation occurs.

We know in reduction reaction, gain of electrons occurs and in oxidation reaction, loss of electrons occurs.

So, in redox reactions, which are a combination of both reduction and oxidation, both gain of electrons and loss of electrons occurs.

3) A single replacement reaction is one where an element in it’s atomic state displaces another element from it’s compound.

Example- 2K + CuSO4 --> K2SO4 + Cu
