Answer:
This stiffening process, called Rigor Mortis, has a roughly known time of occurrence and can therefore be used to estimate time of death. In general: If the body feels warm and no rigor is present, death occurred under 3 hours before. If the body feels warm and stiff, death occurred 3-8 hours earlier.
Answer:
Equation is: 2CH4(g) <----> C2H2(g) + 3H2(g)
Explanation:
In the reaction above;
1.) At equilibrium, the rate of the forward reaction (CH4 decomposing into C2H2 and H2) is equal to the rate of the reverse reaction (C2H2 and H2 reacting to form CH4). This is because it is a reversible reaction.
2.) At equilibrium, the concentrations of all substances are not changing.
3.) At equilibrium, both the forward and reverse reactions are still occurring.
But if the pressure of the system is increased, the equilibrium position will shift to the left according to le Chatelier's principle since there are fewer number of moles of gaseous atoms at the left.
4.7 is the answer!
Mark me brainiest
Answer:
it is C
Explanation:i had this on my test and got it right lol
When we look at the periodic table, it tells us the Sodium is labeled as 'Na'.
