Chlorine is a halogen and all halogens and oxygen, nitrogen and hydrogen are diatomics
Answer:
Because of its weak intermolecular forces.
Explanation:
Hello there!
In this case, according to the given description, it turns out possible for us to recall the chemical structures of both ethanol and dimethyl ether as follows:
Thus, we can see that ethanol have London dispersion forces (C-C bonds), dipole-dipole forces (C-O bonds) and also hydrogen bonds (O-H bonds) which make ethanol a liquid due to the strong hydrogen bonds. On the other hand, we can see that dimethyl ether has just London and dipole forces, which are by far weaker than hydrogen bonding, that makes it unstable when liquid and therefore it tends to vaporize quite readily.
Regards!
Answer:
because it's water chemical bonds form when atoms share electrons and example of a chemical compound is water a water molecule forms when oxygen and hydrogen atoms react and are held together by covalent bonds like other compounds water always has the same chemical composition a ratio of two one of hydrogen atoms to oxygen atoms
Answer:
Partial pressure of gas = mole fraction of the gas x total pressure
Explanation:
In a gas mixture, the partial pressure of each of the gases present in the gas mixture is proportional to the mole fraction of the gases. The pressure exerted by each of the gas in the gas mixture is known as partial pressure. This is independent of the pressures that is exerted by the gases that is present in the mixture. Therefore, total pressure which is exerted by the gas mixture is the summation of the of the partial pressures of each of the gases in the mixture. This is given by Dalton's law of partial pressures.
Mathematically,
Partial pressure of gas = mole fraction of the gas x total pressure
Answer:
60.66 %
Explanation:
The mass percentage of chlorine is 60.66 % chlorine in the compound sodium chloride. To calculate this, add together the mass of one mole of sodium
