The conclusion was that there must be space between the particles of an atom. The way he knew this is because while some of the radiation reflected off of the gold foil, other radiation went right through it.
Hello!
Before I can answer your question we need to know the different types of chemical reactions that can occur:
- Single Replacement
- Double Replacement
- Synthesis
- Decomposition
- Combustion
Combustion is an answer that can usually be ruled out unless oxidation is occuring in the chemical equation (hyrdrogen occuring with oxygen to react)
Synthesis reaction, also known as a Combination reaction, is when the reactants combine to form a single product.
Decompostion is when a single reactant is deconstructed to form multiple products, or the opposite of Synthesis.
With these definitions alone, since they are opposite types of reactions, the answer would be Synthesis and Decomposition reactions !
Hope this helps and if you need anymore clarification feel free to ask.
The correct answer is 3) 2CO2(g) ⇄ 2CO(g) + O2(g)
this is the correct one because it is a decomposition reaction and all the number of atoms is equal on both sides.
there are 2 C atoms on both sides.
and 4 O atoms on both sides.
and 1) the atoms numbers are equal on both sides but not correct as it not a
correct number as it has 1/2 O2.
and 2) CO2(g) ⇆ CO(g) + O2
the number of O atoms is not equal on both sides of the equation.
we have 2 O atoms on the left side and 3 O atoms on the right side.
so, this not a balanced equation.
4) also not correct 2CO(g) + O2 ⇆ 2CO2
as it is not a decomposition reaction and the 2CO & O2 are as reactants not products.
so the correct answer is 3) 2CO2(g) ⇆ 2CO(g) + O2(g)
