Answer: B(water)
Explanation:
Photosystem II uses energy from light to extract electron from water molecule to fill the hole left as the energized electron passes up the chain.When the electrons are removed from the water molecules,the water molecule breaks down into oxygen gas,which bubbles away, and hydrogen ions,which are used to power ATP synthesis.
The enthalpy change accompanying the reaction of 0.95 g of S is -11.85 kJ
<h3>Further explanation</h3>
Given
ΔH° for the reaction is -790 kJ
Required
The enthalpy change
Solution
Reaction
2S (s) + 3O₂(g) = 2SO₃ (g)
mol of S(MW=32 g/mol) :
For 2 mol S, the entalphy = -790kJ
The enthalpy change for 0.03 mol :
Answer:
2 atoms
Explanation:
Because it contain one double bond
Answer: It would be Metalloid
Explanation: I took a test about this and I remember that it was Metalloid.
P.S. Can you tell me if I was right or wrong. Thx
Drawing conclusion is the correct answer.
