The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product).
Answer:
The source of carbon in a glucose molecule produced by photosynthesis is carbon dioxide

Answer:
(D) 2Na+F₂ → 2NaF
Explanation:
The option D is correct because only this equation is balanced.
(D) 2Na+F₂ → 2NaF
There are two atoms of sodium and and fluorine are present on both side of equation so it is balanced. while
(A) 2Al+3O₂ → Al₂O₃
There are two aluminium and six oxygen atoms are present on left side while two aluminium and three oxygen atoms are on right side. So equation is not balanced.
(B) Mg+O₂ → 2MgO
There are one magnesium atom and two oxygen atom on left side while two magnesium and two oxygen on right side. So equation is not balanced
(C) 2Al + F₂ → 2AlF₃
There are two aluminium and two fluorine atom on left side while two aluminium and six fluorine on right side. So equation is not balanced.
An electron will excite when it gets extra energy.
Explanation:
- Matters are made up of atoms and inside the atom, there is a nucleus and electrons. Nucleus has a positive charge and electron has a negative charge. The nucleus is situating at the centre of the atom and the electrons are present on the shells. These electrons having different energy levels but all the electrons are orbit the nucleus in the atom.
- Whenever an electron occupying an energy state which is larger than its ground state, then it is an excited state. Electrons will get excited when they gain some extra energy. The electron will get extra energy when they collide with the nearby particle or atoms, absorbing protons and absorbing packets of light.
