Answer:
C. Co2
Explanation:
Oxygen is a diatomic molecule because 2 atoms are conisistebof a normal molecule.
Answer:
1) magnesium chloride
2) b) The copper is getting oxidized from Cu+ to Cu2+ and turns blue.
Explanation:
The work published by David N. Frick, Sukalyani Banik, and Ryan S. Rypma in J Mol Biol. 2007 Jan 26; 365(4): 1017–1032 clearly shows that divalent metal ions of group 2 such as Mg^2+ play an important role in ATP hydrolysis. Addition of EDTA decreased the rate of hydrolysis of ATP (due to sequestration of the divalent ion of group 2) indicating an active participation of divalent ions in the process.
2) The copper I ion is colourless because it is a d^10 specie. However, when it is oxidized to Cu^2+, a blue colour appears in the solution.
Answer:
The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system.
Answer;
56 kg of water
Solution;
Weight = 62 kg of water in 93 kg of a person
W=km
62=93k;
k=2/3
W=(2/3)84
=56 kg
Therefore; a 84-kg person will have 56 kg of water.
