I very much Disagree. The esophagus runs from your mouth to your stomach.
Answer:
It has 140 neutrons because Mass number= No of protons + no of neutrons
Given the balanced chemical equation for combustion of propane:
Moles of propane 
=3.6 mol
Propane is the limiting reactant as the other reactant oxygen is said to be present in excess.
Amount of products formed would depend on the moles of limiting reactant.
Mole ratio of water to propane as per the balanced chemical equation
=
Calculating the moles of water produced from 3.6 mol propane:
= 14.4mol
Theoretical yield of water = 14.4 mol
Actual yield = 12 mol
Percent yield = 
= 
Answer:
Hey
In science, we have facts, theories, and hypotheses. They all mean something different.
A hypothesis is a complete guess to a problem, and it can't be said that it is correct unless more evidence is found. A good example for this would be the question to "how did the universe get here?" Of course, there are many different hypotheses to this, such as the multiverse theory and also god.
A theory is different than a hypothesis. Many people think that a theory is always wrong and is just a guess (sounds similar to a hypothesis doesn't it.) Well, that's wrong. A theory is an idea about a scientific phenomenon that has sufficient evidence and is said to be the most likely possibility. A good example would be Einstiene's theory of relitavity. Today we know that it is true. The difference between a theory and fact is that a theory could be wrong, That is if there are other theories with as much or more evidence.
There isin't much to say about facts. all I can say is that it is a true statement about a scientific phenomena.
I wrote all that^.
