<u>Organism</u> is one type of species .
<u>Population</u> is a group of same species living together .
<u>Community</u> is a group of different species living together .
<u>Ecosystem</u> is a large group of community of species and its environment consisting of biotic and abiotic factor .
There are several units for expressing energy, Most common are joules and kilocalories.
The conversion factor of joule to kilocalories is
1 kilo calorie = 4184 J
∴ x kilo calorie = 256 J
x =
kilo calories
Thus, 256 J = 0.0611 kilocalories
Answer:
6%
Explanation:
Hello, for this case, we assume that the volume of the solution is 1L, thus, the mass is given by using the density as follows:
Now, the mass of the ethanol:
Finally, the by mass percent is:
%
%m=6%
Best regards.
Answer:
To the right
Explanation:
CH₃OH(g) + heat <=> CO(g) + 2H₂(g)
According to Le Chatelier's principle, a decrease in pressure will shift the equilibrium position to the side where there is a higher volume.
From the balanced equation above,
Volume of reactant = 1
Volume of product = 1 + 2 = 3
From the above, we can see that the volume of the gasous product is higher than the volume of the gasous reactant.
Therefore, a decrease in the pressure of the system will shift the equilibrium position to the right.
Explanation:
The atomic number is equal to the number of protons in an atom's nucleus. Hydrogen's atomic number is 1 because all hydrogen atoms contain exactly one proton.
