The entire quiz question bank! This quiz pulls questions at random from the entire 1100+ question-bank Loading... 1. Explain, by referring to the electronic configurations, why lithium is less reactive than sodium.Sodium has the electronic configuration 2,8,1 and lithium has 2,8,8,1. The outer electron in lithium is less attracted to the nucleus than in sodium because it is further away. So lithium is more reactive than sodiumSodium has the electronic configuration 2,8,1 and lithium has 2,1. The outer electron lost from sodium is closer to the nucleus therefore the electron is more attracted by the nucleus. So sodium is more reactive than lithiumSodium has the electronic configuration 2,8,1 and lithium has 2,8,8,1. The outer electron in lithium is more attracted to the nucleus than in sodium because it is further away. So sodium is more reactive than lithiumSodium has the electronic configuration 2,8,1 and lithium has 2,1. The outer electron lost from sodium is further from the nucleus therefore the electron is less attracted by the nucleus. So sodium is more reactive than lithiumQuestion 1 of 10 Loading... 2. What is the formula for silver sulfate?Ag₂SO₄AgSAg(SO₄)₂AgS₂Question 2 of 10 Loading... 3. What is the formula for potassium sulfate?K(SO₄)₂K₂SO₄K₃S₂K₂SQuestion 3 of 10 Loading... 4. What is the formula for potassium bromide?K₂BrKBr₂KBrKBr₃Question 4 of 10 Loading... 5. How many electrons in a fluoride ion?102919Question 5 of 10 Loading... 6. The overall equation for the decomposition of water is: 2H₂O(l) → 2H₂(g) + O₂(g) Use this equation to explain why the volume of hydrogen collected should be twice that of the volume of oxygen.There are more moles of oxygen than hydrogenHydrogen has a much lower Mᵣ so more gas is produced for the same number of molesHydrogen is a lighter gas than oxygen so rises fasterThe number of moles of H₂ are twice that of oxygenQuestion 6 of 10 Loading... 7. If a substance has a simple molecular structure, what physical state might it be at room temperature?SolidGas or liquidAny stateSolid or liquidQuestion 7 of 10 Loading... 8. Are displacement reactions exothermic or endothermic?Depends on the temperature of the surroundingsDepends on the reagentsEndothermicExothermicQuestion 8 of 10 Loading... 9. State the problem associated with sulfur dioxide in the atomosphere?The sulfur dioxide can react with nitrous oxides to form acidic particulatesThe sulfur dioxide causes increased levels of radicals in the atmosphere leading to the destruction of the ozone layerThe sulfur dioxide combines with water in the atmosphere to form acidic solutions (acid rain)The sulfur dioxide is poisonous because it reduces the blood\'s capacity to carry oxygenQuestion 9 of 10 Loading... 10. Is potassium carbonate soluble?yesslightlynoQuestion 10 of 10 Loading...
