Six molecules of oxygen.
6 CO2 + 6 H2O ----> 6 C6H12O6 + 6 O2
Answer:- The wavelength is 
and the right option is D.
Solution:- Wavelength is inversely proportional to the frequency and the equation is:
where, 
is the wavelength, c is the speed of light and 
is frequency.
Frequency is 
and the speed of light is 
.
Since, 
So, 
Let's plug in the values in the equation:
Hence, the right option is D) .
Answer: science is the systematic way of gaining knowledge about nature
Answer:
2.60 g of H₂ and 20.8 g of O₂ are produced in the decomposition of 23.44 g of water
Explanation:
Water decomposition is:
2H₂O → 2H₂ + O₂
We convert the mass of water, to moles:
23.44 g . 1 mol/18 g = 1.30 moles
Ratio is 2:2 with hydrogen and 2:1 with oxygen. Let's make rules of three:
2 moles of water can produce 2 moles of hydrogen gas and oxygen gas
Then, 1.30 moles will produce:
(1.30 . 2) /2 = 1.30 moles of H₂
(1.30 . 1) /2 = 0.65 moles of O₂
We convert the moles to mass
1.30 moles of H₂ . 2g / 1mol = 2.60 g of H₂
0.65 moles of O₂ . 32 g / 1 mol = 20.8 g of O₂
