Sulfur would be the answer
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:
It would take 15 sticks of butter
Explanation:
2 divided by 20 is 0.1
0.1 is how much butter for 1 so now we multiply that by 150
0.1 x 150 = 15
Therefore, you would need 15 sticks of butter for 150 cookies
Answer: -
Solubility of a substance depend on the balance of intermolecular forces between the solvent and solute, and the entropy change that accompanies this process.
Temperature and pressure also plays a role in solubility.
A solution having Group 1 cations like lithium, sodium, potassium etc are always soluble.
A solution having NH₄⁺ is soluble.
All salts with anion as nitrates, acetates, chlorates, and perchlorates are soluble in water.
Answer:
0.125
Explanation:
no of moles = given mass / molar mass
no of moles = 7/
molar mass of calcium oxide = atomic mass of calcium + oxygen
molar mass = 40 + 16
molar mass = 56
no of moles = 7/ 56 = 1/8 = 0.125
