Metals or non-metals

if you know it can you also add the metal/non-metal that is being discribed.

a) A yellow crystalline solid that burns with a bright blue flame in oxygen, giving a gas which dissolves in water to give an acidic solution.

b) a soft silvery solid that burns in oxygen with an orange flame to give a white oxide. when water is added to the oxide, the solution is strongly alkaline.

c) A brown, flexible solid that forms a black oxide when heated in oxygen. the oxide is insoluble in water.

d) a shiny grey solid that burns if heated very strongly in oxygen. the gas produced turns lime water milky and produces a slightly acidic solution.

a) Non-metal - Sulphur

b) Metal - Calcium

c) Metal - Copper

d) Non-metal - Carbon

Hope this helps.

But in case you're not sure, sulphur and carbon are non-metals, while lithium and copper are metals.

Hope this helps! :)
