Answer:
A magnet,
Explanation: -you can cause current to flow,
The magnet moves electrons in the wire arround, only moving it about the coil or the other way arround is necaserry.
Answer:
This is due to more hydrogen bonding in ethylene glycol than it is in isopropyl alcohol
Explanation:
The boiling point of isopropyl alcohol is 82.4 °C it contains only a single OH group, hence intermolecular hydrogen bonding is solely responsible for it's boiling point, whereas Ethylene glycol (CH2OHCH2OH) contains 2-OH group and both intermolecular and intramolecular hydrogen bonding are responsible for the higher boiling point of ethylene glycol at 198 °C.
The method used to separate oxygen from mercury oxide is by strong heating. In the lab mercury oxide is placed in strong glass test tube and strong heat applied to the test tube. Mercury oxide then undergoes a decomposition reaction to produce mecury and oxygen.
Antoine Lavoisier , the father of modern chemistry is the one credited as having proved the decomposition of mercuric oxide by heating, and that the result was production of mercury and oxygen.
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
Answer:
Look at the properties of Oxygen and Silicon - the two most abundant elements in the Earth's crust - by clicking on their symbols on the Periodic Table.
