Answer:
5.231 L.
Explanation:
- Molarity is the no. of moles of solute per 1.0 L of the solution.
<em>M = (no. of moles of KCl)/(Volume of the solution (L))</em>
<em></em>
M = 6.5 M.
no. of moles of solute = 34.0 mol,
Volume of the solution = ??? L.
∴ (6.5 M) = (34.0 mol)/(Volume of the solution (L))
∴ (Volume of the solution (L) = (34.0 mol)/(6.5 M) = 5.231 L.
There is 103 percent of water in hydrate
Answer:
Option A
250 degrees Celcius
Explanation:
If 1046J of heat energy is added to water, the water will experience a rise in temperature, at a rate that is directly proportional to its specific heat capacity.
Mathematically, this can be seen as ![Q=C\Delta T](https://tex.z-dn.net/?f=Q%3DC%5CDelta%20T)
Where C = specific heat of water = 4.184 J/g • °C.
Q = heat energy = 1046 J
![\Delta T =1046/4.148=250 degrees Celcius](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D1046%2F4.148%3D250%20degrees%20Celcius)
Therefore, the increase in temperature that will be experienced, is for 250 degrees Celcius
Answer:
Pollution, non native species being introduced, and other human activities
Explanation:
Human activities affect marine ecosystems as a result of pollution, overfishing, the introduction of invasive species,and acidification, which all impact on the marine food web and may lead to largely unknown consequences for the biodiversity and survival of marine life forms.
