Why are metal oxides base and non-metallic oxides acid? please use organic chemistry's knowledge.
3) Metal oxides become less basic (more acidic) as the oxidation state increases. Explain w be specific! (2 marks)
Oxides can either be acidic or basic, based on the type of the bonding in the oxide. Covalent oxides tend to be acidic, while ionic oxides tend to be basic. Arrange the following oxides in order of increasing acidity Note: 1 = most acidic; 6 = least acidic P&O 10 [Select] CaO (Select] SiO2 | Select] N2O5 [Select] Al2O3 [Select)
Q7) A 1.23 g sample, which contains gold (Au), silver (Ag) and metal oxides, is treated with concentrated nitric acid (HNO;), which dissolves all the metals and metal oxides with the exception of the gold. The mass of yellow metal remaining is 7.4 x 10 g. The solution is then treated with aqueous sodium chloride (NaCI), which precipitates silver chloride (AgCI) and nothing else. A total of 0.196 g of AgCl is obtained. What is the percent gold and silver...
Classify these oxides as acidic, basic, or amphoteric. Acidic Basic Amphoteric MgO Br207 K20P4010 Al203
Amphoteric oxides exhibit both acidic and basic properties. True False
4. Imagine that you are given two metal oxides to study in the lab. You heat each oxide in a small test tube and then insert a glowing splint into each. You observe that the splint in tube 1 immediately ignites and burns with a steady flame before it dies, but the splint in tube 2 does not. a) (2 pts) What happened to the metal oxide in tube 1 when it was heated? b) (4 pts) Do both metal...
Reaction of metals with Oxygen: metal + O2 (air) --> metal oxides Metals used: iron, tin, copper, magnesium, aluminum, and zinc 1) of these metals, do any burn (react) with oxygen? 2) Could you suggest an ingredient for making flares?
Explain why a weak acid solution has a higher pH than a strong acid solution concentration. of the same Explain why the equivalence point of a weak acid titrated with a strong base occurs at a basic pH.
Question 8 (3 points) 4th row periodic trend involving metal cations, such as potassium, calcium, iron(ili) and copper(II)ions form, acidic solutions via the hydrolysis of water and the Arrhenius model. True False Question 14 (3 points) Bicarbonate ions may disproportionate into carbonic acid and the carbonate ion. True False Question 17 (3 points) Which of the following metal oxides upon dissolution and dissociation create strong basic solutions in water? All Group IA (1) oxides Group IA (1), except Li and...
