Adenine , guanine, cytosine and thymine
The main premise of an isomer is that it is a molecule with the same molecular formula but some sort of difference between the molecule and the isomer. Geometric isomers have the same structure and vary differently, the other non isomer answers are red herrings really and so the correct answer would be structural isomer as these are molecules with the same formula but are structurally different or the atoms are arranged in different ways. Hope that helps!!
Answer:
C
Explanation:
Just look at the reactants.
2AgCl + BaBr2
The first reactant is made of 2 elements.
The second reactant is made of 2 elements.
It can't be a decomposition. At this level there is only one reactant made of 2 elements. Something like
2MgO ===> 2Mg + O2
is a decomposition. One compound breaking down into 2 elements Mg and O.
It can't be a combustion. One of the reactants in a combustion is oxygen. Those equations look like
C3H8 + 5O2 ==> 3CO2 + 4H2O
That would be what a combustion looks like
It can't be a single replacement. They look like
Mg + CuO ===> Cu + MgO
There are elements on both sides of the reaction.
that leaves a double replacement which I wrote about how you distinguish it.
The kind of seismic waves travel through the earth are Congressional longitudinal waves and shear transverse waves.
Explanation:
- There are two kinds of seismic waves and they are the Congressional longitudinal waves and shear transverse waves.
- They are called the P waves and S waves when they pass through the earth.
- P waves are the primary because they are the fastest waves whereas S waves are the secondary since they are slower
- P waves move as alternate compressions and dilations along the side of propagation
- S waves move as alternate compression and transverse motion along the perpendicular side of propagation.
