Mg has similar properties to barium
Answer:
15.46%
0.667 g/mL (more o less) 0.052 g/mL (standard deviation)
Explanation:
To solve the problem, it is necessary calculate the average:
(0.608 g/mL + 0.705 g/mL + and 0.689 g/mL) / 3= 0.667 g/mL
standard deviation= 0.052
Now, let us calculate the % error:
[(0.789 g/mL - 0.667 g/mL) / 0.789 g/mL] * 100% = 15.46%
One species will often exhibit an advantage in
resource use. This superior competitor will out-compete the other with more
efficient use of the limiting resource. As a result, the inferior competitor
will suffer a decline in population over time. It will be excluded from the
area and replaced by the superior competitor. Without it and having intra-specific
and inter-specific relationships in a community will lead to a harmonious community
and maintain the biodiversity.
We are going to use Henry's law:
when C1/P1 = C2/P2
at a constant temperature.
and when the C1 and C2 are the concentration of the gases ( the solubility)
and P1 and P2 is the Pressure 1 and pressure 2
and when 760 mmHg = 1 atm
so, by substitution:
1.6 g/L / 1 atm = C2 /2.5 atm
∴C2 = 1.6g/L *2.5atm /1 atm
= 4 g/L
