Answer:
Silicon (Si) would be the answer
Explanation:
There are 1000 meters in 1 Kilometer.
Hope this helps you. :)
B. Space for the solute and the solvent
Answer:
-0.74
Explanation:
Let's consider the following redox reaction.
AgCl(s) + NO(g) → Ag(s) + Cl⁻(aq) + NO₃⁻(aq)
We can identify the oxidation and reduction half-reactions.
Reduction (cathode): 1 e⁻ + AgCl(s) → Ag(s) + Cl⁻(aq)
Oxidation (anode): 2 H₂O(l) + NO(g) → NO₃⁻(aq) + 4H⁺(aq) + 3 e⁻
The standard cell potential (E°) is equal to the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode.
E° = E°red,cat - Ered,an = 0.22 V - 0.96 V = -0.74 V

Here's what I get
Explanation:
A physical property is one you can observe without changing the chemical composition of a substance.
A chemical property is one you can observe only by changing the chemical composition of a substance.
In this problem, examples of physical properties are:
