Answer:
A; C6H12O6 + 6O2
Explanation:
You can easily differentiate between the reactants and the products, as the reactants are on the left, while the products are on the right.
When sodium carbonate and magnesium nitrate solutions are combined, a precipitate is created as a result of a double-displacement process. As you balance the chemical equation, make predictions about the reaction's byproducts.
<h3>What occurs when magnesium sulfate and sodium carbonate are combined?</h3>
A solid may form when the solutions of two soluble salts are combined. Salts that are insoluble are created during precipitation processes. When magnesium sulfate and sodium carbonate are combined, magnesium carbonate, an insoluble salt, results.
<h3>What happens when hydrochloric acid and sodium carbonate interact?</h3>
What takes place when sodium carbonate and hydrochloric acid interact? When sodium carbonate is added to hydrochloric acid, a double displacement reaction takes place, resulting in the formation of sodium chloride, water, and carbon dioxide. The sodium carbonate and the two moles of HCl combine to generate carbonic acid.

Answer is: the discovery of sub atomic particles like electrons.
J. J. Thomson discovered the electron in 1897.
His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.
With this model, he abandoned his earlier hypothesis (the atom was composed of immaterial vortices).
J.J. Thomson placed two oppositely charged electric plates around the cathode ray. He did experiments using different metals as electrode materials and found that the properties of the cathode ray remained constant no matter what cathode material he used.
Tomson concluded that atoms are divisible and that the corpuscles are their building blocks (atoms are made up of smaller particles).
Answer:
it identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional group
Explanation:
It turns from turquoise to yellow or orange when it reacts with reducing sugars.
Answer:
Mole fraction O₂= 0.43
Explanation:
Mole fraction is the moles of gas/ total moles.
Let's determine the moles of each:
Moles O₂ → 15.1 g / 16 g/mol = 0.94
Moles N₂ → 8.19 g / 14 g/mol = 0.013
Moles H₂ → 2.46 / 2 g/mol = 1.23
Total moles = 2.183
Mole fraction O₂= 0.94 / 2.183 → 0.43
