Answer:
Explanation:
Replication is crucial to science. Every time researcher find something surprising that has to do with science they replicate it.
The question is incomplete, the complete question is;
The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube, as shown in the diagram below. The volume is measured to be 45.6mL . The atmospheric pressure in the lab is measured as 765 torr , and the equilibrium vapor pressure of water at 298 K is 24 torr .(i) The pressure inside the tube due to the H2(g)
Answer:
741 torr
Explanation:
From the question we can see that the atmospheric pressure in the lab is 765 torr.
The vapour pressure of water = 24 torr
From Dalton's law of partial pressure, we know that;
Total pressure = Pressure of the H2 + Partial pressure of water vapour
Therefore;
Pressure of H2 = Total pressure - Partial pressure of water vapour
Pressure of H2 = 765 torr - 24 torr = 741 torr
Answer:
It copies itself and gives instructions for building cells.
It provides energy to cells and passes from parent to offspring
Explanation:
The DNA is the genetic materials of the cell upon which any form of inheritance is predicated.
This giant molecules is a very important organelle in all living organisms. It has a double helix structure and can be found within the nucleus.
- The DNA copies itself and gives instruction for building cells.
- It has important information needed by the cell to produce protein so DNA replication is a vital process.
- The DNA is also able to ration energy within the cell.
- It passes genetic materials from parents to offspring
Diamond is the hardest naturally occurring substance found on Earth.
