Question 4 of 16 Which chemical equation models a synthesis reaction ? O A. 2Na+MgCl 2 2NaCl+Mg O B. H 2 O+CO 2 H 2 CO 3 C. HCl+LiOH LiCl+H 2 O O CO 2 C+O 2

The chemical equation which is a model of synthesis reaction is option B

B. H₂O + CO₂ ---> H₂CO₃

Explanation:

A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.

A synthesis reaction is illustrated below:

A + B > C

In the illustration above, A and B are two chemical substances which serve as the reactants in the chemical reaction. A and B combine with each other to form a product C.

Common synthesis reaction include:

1. The reaction of sodium with chlorine to produce sodium chloride: Na + Cl ---> NaCl

2. The synthesis of Nitrogen (iv) oxide from nitrogen (ii) oxide and oxygen: 2NO + O₂ ---> 2NO₂

3. The synthesis of sulfur trioxide from sulfur dioxide and oxygen: 2SO₂ + O₂ > 2SO₃

From the given chemical reactions, the model of a synthesis reaction is option B

H₂O + CO₂ ---> H₂CO₃

Answer and Explanation:

The magnitude of the foliar area defines the capacity of the plant in intercepting photosynthetic radiation, which is the principal source of energy used by plants for the tissues and food elaboration. The bigger the foliar area is the better photosynthetic capabilities the plant has. Variations in the size of leaves correspond to variation in the amount of solar radiation intercepted. The spatial arrangement of leaves in the whole plant is also related to the individual strategy for intercepting radiation.  

The plant shown in the picture seems to have a very developed aerial part, growth in height, long stems, and huge leaves with an alternate arrangement. They probably become important competitors to their neighbors because of their size. Competition is probably related to space, but considering that all the species that are near this plant are much smaller, competition might be related to space in the ground and not necessarily competition for aerial space .
