1) which of the following is the general equation for a synthesis reaction?
a) ab-> a+b

b) a+b-> ab

c) a+bc-> b+ac

d) ab+cd-> ad+bc

2)which of the following takes place during a redox reaction?

a)electrons are gained only.

b)electrons are lost only.

c)electrons are both gained and lost.

d)electrons are neither gained or lost.

3)what is a single replacement reaction?

*bonus question for sonic the hedgehog fans*

what are the names of sonic the hedgehogs father, uncle, mother, and dog?

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

4)For sonic hedgehogs,

Father is Jules Hedgehog

Mother is Queen Aleena

Uncle is Professor Charles the Hedgehog

Dog is Muttski

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
