No because observing a physical property of a substance is just observing like color or texture. They don't change. Physical properties do not change the composition of a substance and neither do physical changes.
5 meters = 0.005 km
3 grams = 3,000 milligrams
7 meters = 700 centimeters
Im not sure about #4
2.5 meters = 2,500 mm
77 meters # 770 Dec I meters
0.002 cm = 0.02 mm
44 mm = 0.044 meters
Answer:
Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s).
Explanation:
- Since E°Ag⁺ is more positive (+ 0.80 V) than that of E°Cu²⁺ (+ 0.34 V).
So, Ag will be the cathode that the reduction reaction is occurred on it and Cu will be the anode where the oxidation reaction is occurred on it.
Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s).
- Ag⁺ is reduced to Ag and Cu is oxidized to Cu²⁺.
Q: Which type of severe weather is related to high-pressure systems
A: A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies. A high pressure system is represented as a big, blue H.
If you take this answer into consideration knowing the weathers, you will get your answer
