Metabolism involves the over-all chemical reactions of the body. It is divided into two kinds. The first one is catabolism which is the breaking down of molecules to acquire energy. Anabolism, the other type, is the synthesis of all the molecules that are needed by the cells.
Answer:
Water, up
Explanation:
In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.
Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.
Answer:
THE EQUILIBRIUM CONSTANT EXPRESSION Kc = ![\frac{[C2H5OH]}{[C2H5OC2H5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OH%5D%7D%7B%5BC2H5OC2H5%5D%7D)
Explanation:
The equilibrium constant, Kc is an expression given by the ratio of the concentrations of the products over the reactants. TN.B: the activities of pure solids and liquids are equal to 1.
Kc = ![\frac{[products]^n}{[reactants]^n}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bproducts%5D%5En%7D%7B%5Breactants%5D%5En%7D)
where n= no of moles
Reaction equation:
2C2H5OH 
→ C2H5OC2H5
⇒ Kc = ![\frac{[C2H5OC2H5] [H2)]}{[C2H5OH]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OC2H5%5D%20%5BH2%29%5D%7D%7B%5BC2H5OH%5D%5E2%7D)
but [H20] = 1
∴ Kc =
Answer:
c. Protons, electrons
Explanation:
The number of these electrons in a neutral atom is equivalent to the number of protons.
Since protons have positive charge, they balanace the negative charge of electrons. Electrons have same level of charge per particle as a proton.
Neutrons posses no charge, so in a "neutral atom" the number of proton is equal to that of electrons, othermeans it will not be neutral.
When a electron is removed by natural or artificaial means , an ion results which is an electrically charged particle. It also happens some atoms take additonal electrons once they were previously neutral. They can also lose electrons and become positively charged,
