Auf dem Weg ins Jahr 2018 ist es an der Zeit, einen Blick zurück auf einige der größten Wissenschaftsnachrichten des vergangenen Jahres zu werfen. Die diesjährigen Nachrichten enthielten giftige Frösche, Batteriebrände, Elementbildung und vieles mehr!
Here’s the start of a new series of collaborations withMEL Science, looking at a number of fun chemistry experiments and the explanations behind them. Today’s initial offering looks at how zinc pellets can be transformed into tin hedgehogs with some simple chemistry.
The Chemistry of their Environmental Effects
Many of us enjoyed watching spectacular fireworks displays to usher in the new year. However, the vibrant colours of fireworks belie the effects that they can have on the environment. With this graphic, we take a look at some of the issues that they can cause.
Thallium, ‘The Poisoner’s Poison’
Having already looked at arsenic and cyanide in the previous instalments in this series, our attention turns to thallium, another famed poison. Thallium perhaps doesn’t share quite the same profile as arsenic and cyanide, but despite this it’s perhaps an even more effective compound in ...
It’s Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. We’ve looked at fireworks in a previous post,so this time around it’s time to take a look at the chemicals that go into producing sparklers, and their various roles. In sparklers, there are ...
In the wake of the recent announcement of a new £1 coin to be introduced in 2017, today’s post looks at some of the metals present in the coins of the United Kingdom. All of these coins are produced using alloys, or mixtures of metals; the main metals used include copper, nickel, zinc and iron. ...
Today’s post looks at an aspect of chemistry we come across every day: alloys.Alloys make up parts of buildings, transport, coins, and plenty of other objects in our daily lives. But what are the different alloys we use made up of, and why do we use them instead of elemental metals? The graphic ...
The metal reactivity series is a commonly taught concept in chemistry, placing the metals, as its name suggests, in order of reactivity from most reactive to least reactive. It’s also a useful tool in predicting the products of simple displacement reactions involving two different metals, as well ...
The colours in fireworks stem from a wide variety of metal compounds – particularly metal salts. ‘Salt’ as a word conjures up images of the normal table salt you probably use every day; whilst this is one type of salt (sodium chloride), in chemistry ‘salt’ refers to any compound thatcontains ...
