Answer:
0.765 moles H₂O
Explanation:
Based on the reaction:
2 H₂O₂ → 2 H₂O + O₂
2 moles of H₂O₂ produce 2 moles of H₂O
26g of H₂O₂ are:
26.0g H₂O₂ × (1mol / 34g) = 0.765 moles of H₂O₂.
Moles of H₂O are:
0.765 mol H₂O₂ × (2 mol H₂O / 2 mol H₂O₂) = <em>0.765 moles H₂O</em>.
That means, 0.765 moles of H₂O are produced from 26.0g of H₂O₂
The molar mass of the components making up Ca(NO₃)₂ are as follows;
Ca - 40 g/mol
N - 14 g/mol
O - 16 g/mol
the molar mass of the compound is calculated as follows;
Ca(NO₃)₂ --> 40 + 2(14 + 16x3)
= 164 g/mol
1 mol of the compound weighs 164 g
Therefore 0.433 mol = 164 g/mol x 0.433 mol
= 71.0g
the mass of 0.433 mol of the compound is 71.0 g

<h3>What is visible spectrum?</h3>
The visible light spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye. Simply put, this range of wavelengths is known as visible light.
The visible spectrum, also known as the optical spectrum, is the portion of the electromagnetic spectrum whose radiation consists of photons capable of sensitizing a normal person's human eye. The corresponding visible light radiation range is identified.
That being said, plant 3 is situated in front of a green stained glass window.
Plants have chlorophyll pigment that reflects back green light, making green light less effective for photosynthesis and causing them to die as quickly as if they were kept in the dark.
Thus, the correct option is C.
