Which list BEST identifies how the arrows should be arranged around the paper leaf in the model to represent the movement of mat
Andrew [12]

Answer:

D. Point into Leaf: water(H₂O), carbon dioxide (CO₂) sunlight, Point away from leaf: Sugars, oxygen (O₂)

Explanation:

Photosynthesis is the process used in the production of chemical energy in the form of energy containing organic compounds and oxygen from atmospheric carbon dioxide and liquid water enabled with the energy captured from light (mainly Sunlight) by the chlorophyll in green plants and other organisms

The basic chemical reaction involved in a photosynthesis reaction is presented as follows;

{}                                    Sunlight

{}                                          ↓

{}       CO₂           +  H₂O (l)  →   C₆H₁₂O₆   +    O₂

Carbon dioxide {}  Water        Glucose       Oxygen

Write a balanced equilibrium equation for the dissolution of nai in water. include phases.
Bess [88]
Dissolution means to make the compound apart, So when we have ionic compounds like NaI which has metal and non-metal ions, It separates into parts of positive ions and negative ions. After we separate this compound apart we will put the charge of each on above its symbol and then start to balance the equation of the dissolution.

So the dissolution equation of NaI is:
NaI(s) → Na^+(s)  +   I^-(Aqu)
