they have knowledge about the name of medicine and the disease it cured
Yes you add water to calcium oxide it makes calcium hydroxide
Answer:
Photosystems PSI (P700) and PSII (P680) and photolysis of water releases energy
In the form of movement of electrons which is later extracted as ATP
Explanation:
On absorbing light energy electrons obtained from photolysis of water and those present in and those present in the reaction centres PSI and PSII move to the higher energy level and electron acceptors accept them. They then move down through the electron transport chain to the lower energy level during which ATP is produced which is a chemical form of energy.

Answer:</h3>
0.255 moles
<h3>
Explanation:</h3>
- The relationship between moles, mass and the molar mass of a compound is given by;
- Molar mass of a compound is equivalent to the relative formula mass of a compound that is calculated by adding the atomic masses of atoms making the compound.
In our case.
We are given the compound PCl₃ whose;
Mass is 35 g
Molar mass is 137.33 g/mol
But;
Therefore;
= 0.255 moles
Therefore, 35 g of PCl₃ contains 0.255 moles
the energy of motion. energy of a moving object is equal to the work required to bring it to its speed from rest, or the work the object can do while being brought to rest. energy of a moving object is equal to the work required to bring up to speed or bring it to rest.
