Answer:
Gold, Water
Explanation:
which their molecules can not be broken down.
Answer:
84.24 g
Explanation:
Given data:
Mass of oxygen = 75 g
Mass of Al required to react = ?
Solution:
Chemical equation:
4Al + 3O₂ → 2Al₂O₃
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 75 g/ 32 g/mol
Number of moles = 2.34 mol
Now we will compare the moles of oxygen with Al.
O₂ : Al
3 : 4
2.34 : 4/3×2.34 = 3.12 mol
Mass of Al required:
Mass = number of moles × molar mass
Mass = 3.12 mol × 27 g/mol
Mass = 84.24 g
The equation that represents photosynthesis is ,

The correct option is (c).

What is photosynthesis?
•This is process performed by green plants to prepare its food using sunlight and carbon dioxide.
•Oxygen and Glucose are the products obtained after photosynthesis.
•This process takes place in chlorophyll of a cell(in chloroplasts)
•These are of two types , light dependent reactions and light independent reactions
•This is was first discovered by Jan Ingenhouse.
Answer:
The balanced equation would be
2Na(s) + 2H2O(l) ===> 2NaOH(aq) + H2(g)
where
s---solid
l--- liquid
aq--- aqueous
g---- gas
Are the states of each substance
