Hi.
From the knowledge I have left of biology, I have to go with D. Decomposers
Hope this helps!
Answer:
0.133
Explanation:
reaction between KIO3 and KI in acidic medium
IO3⁻ +5I⁻ +6h⁺ → 3I₂ + 3H₂O
I₂ reacts with thiosulphate
NaS₂O₃ → 2Na⁺ + S₂O₃²⁻
net reaction
IO⁻₃ + 6H⁺ + 6S₂O₃³⁻ → I⁻ + 3S₄O₆²⁻ + 3H₂O
mole of KIO₃
= molarity x volume
= 0.00002mol
a mole of KIO₃ has reaction with 6 mol of S₂O₃²⁻
= 2x6x10⁻⁵
= 0.00012 mol
volume = 0.90 ml
1 ml = 0.001L
0.90ML = 0.0009L
to get concentration,
molarity/volume
= 0.00012/0.0009
= 0.133m
True. this is called an ionic bond
Answer:
C. Parasitism
Explanation:
Mutualism means both organisms benefit. An example of this is a bee and flower.
Commensalism means one organism benefits and the other is unaffected. An example of this is a whale and barnacles.
Parasitism means one organism benefits, and the other is harmed. An example of this other than mosquito and human is a dog and fleas.
Hope this helps!!
