worty [1.4K]

Answer:Ethyne

Explanation:

Ethyne is more commonly known under the trivial name acetylene. It is the simplest of the alkynes, consisting of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom. Since both carbon atoms are linear in shape, all four atoms lie in a straight line.

How are the reactants represented in the chemical equation for photosynthesis? 6co2 o2 6co2 6h2o c6h12o6 6o2 c6h12o6 6h2o
Vika [28.1K]

The reactants of photosynthesis are represented by 6CO_2 and 6H_2O.

<h3>Photosynthesis</h3>

It is a reaction through which green plants make use of inorganic products such as water and carbon dioxide in the presence of solar radiation to make sugar. Oxygen is liberated as a by-product.

The equation of the reaction is represented by:

6CO_2 + 6H_2O --- > C_6H_{12}O_6 + 6O_2

Thus, the reactants are represented by  6CO_2 and 6H_2O respectively.

Fewer bubbles will be produced because of fewer collisions of reactant molecules

Explanation:

As the solid dissolves into the solution after the liquid has been vigorously bubbled, if the temperature of the liquid is reduced a little, what will happen is that fewer bubbles will be produced as a result of lesser amount of collisions occurring between the reactant molecules
