Answer:
H⁺(aq)
Explanation:
Let's consider the following redox reaction.
Sn(s) + 2 H⁺(aq) → Sn²⁺(aq) + H₂(g)
We can identify both half-reactions.
Oxidation: Sn(s) → Sn²⁺(aq) + 2 e⁻
Reduction: 2 H⁺(aq) + 2 e⁻ → H₂(g)
Sn(s) undergoes oxidation so it is the reducing agent, while H⁺(aq) undergoes reduction so it is the oxidizing agent.
Answer:
Red, orange, yellow, green, blue, indigo, and violet.
Explanation:
These are the colors that light takes on when split using a prism. These are the same colors that are in a rainbow. You can remeber these colors using this acronym:
R.O.Y G. B.I.V
It's kinda like a name!
Answer:
161 atoms
Explanation:
A sample of propane, C3H8, contains 14.6 moles of carbon atoms. How many total moles of atoms does the sample contain
every molecule of propane contains 3+8=11 atoms
so
14.6 moles contain 14.6 X 11 = 161 atoms
Yes barium carbonate forms a ppt. it is insoluble in water
Their cells have a nucleus and membrane-bound organelles.
