Causes changes in Ecosystems
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems
I hope it helps.. if it doesn’t please comment I’ll post another answer..
Answer:
3I^-/I3^-//Tl3^+//Tl^+
Explanation:
Based on the given reduction potentials, the half reaction equation having greater positive value will be the cathode while the half reaction equation having less positive reduction potential will be the anode.
This implies that this equation:
Tl3+ (aq) + 2e- → Tl+ (aq) ξo = 1.24 occurs at the cathode
While:
3 I- (aq) → I3- (aq) + 2e- ξo = -0.55 occurs at the anode
Cell notation,
Anode//cathode
Hence for this system under consideration:
3I^-/I3^-//Tl3^+//Tl^+
Isn't the answer is 20 m/s?
Answer:
3.25×10²⁴ molecules
Explanation:
From the question given above, the following data were obtained:
Mass of H₂O = 97.2 g
Number of molecule of H₂O =?
From Avogadro's hypothesis, we understood that:
1 mole of H₂O = 6.02×10²³ molecules
Next, we shall determine the mass of 1 mole of H₂O. This can be obtained as follow:
1 mole of H₂O = (2×1) + 16
= 2 + 16
= 18 g
Thus,
18 g of H₂O = 6.02×10²³ molecules
Finally, we shall determine the number of molecules in 97.2 g of H₂O. This can be obtained as follow:
18 g of H₂O = 6.02×10²³ molecules
Therefore,
97.2 g of H₂O = 97.2 × 6.02×10²³ / 18
97.2 g of H₂O = 3.25×10²⁴ molecules
Thus, 97.2 g of H₂O contains 3.25×10²⁴ molecules.
A gas can move around freely while a solid is hard and can’t move around freely
