In a chemical experiment, we need a metal that is very reactive. Which one is it? A. Gold B. Silver C. Sodium D. Platinum 相关知识点: 试题来源: 解析 C。在化学实验中,钠是一种非常活泼的金属,而金、银、铂相对不活泼。反馈 收藏 ...
the easier the metal to lose an e- (s).Reason 2: Since there is an e- - e- repulsive force % each shells the actual nuclear attractive force Z faced by the outermost shell e- will not equal the nuclear charge. It will be weaker instead. This is called screening /shieldi...
更新1: One last question... If the first element of group 1 pares to the last element of group 2... Which is more reactive? And which element of group 2 equals to the reactivity of any element in group 1? For example Ba = Na?? Just for an example..Your question is...
Some metals are alsoreactive; for example, aluminum can react with acidic foods and potentiallycontaminate them with leached particles. The initial cost of high-quality metal equipment is another disadvantage, particularly for smaller food service businesses that can’t afford significa...
A carrier for chromatography or a carrier for a pre-treatment comprises a carrier material consisting of a metal or a metal compound reactive with the sulfur-containing compound or a carrier material whose surface is coated with the foregoing metal or metal compound; and a sulfur-containing ...

An improved adsorbent for ozone comprises a crystalline aluminosilicate in which at least 90% of the exchangeable cation content is in the acid form and further which contains between 0.5 and 20 wt % of one or more adsorbed components which are non-reactive with ozone. Preferably the adsorbed ...
aithium batteries contain lithium metal,organic solvents and others reactive materials,which are combustible. Care must be exercises,when handling lithium batteries to eusure that short circuiting ,puncturing or deformation does not occur which may result in heat generation,leakage,explosion or possibilit...
