Oxygen gas expands in a container and when pressure is applied it liquifies and occupies a smaller volume
hope that helps <span />
Answer:
D.
Explanation:
Hydroxide ions are produced when acid reacts with a base under a Ph value of more than 7. Hydroxide ions are negatively charged ions which are released in the aqueous solution during titration process. It a oxygen and hydrogen atom covalent bond.
Answer : The volume of the balloon will be, 0.494 liters
Solution :
Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = ?
= final volume of gas = 0.54 L
= initial temperature of gas = 273.15 K
= final temperature of gas = 298.5 K
Now put all the given values in the above equation, we get the initial volume of balloon.
Therefore, the volume of the balloon will be, 0.494 liters
Answer:
Water is a good solvent for ionic compounds as the amount of energy released by forming ion-dipole interactions between water molecules and charged ions is sufficient to compensate for the amount of energy required to break ionic bonds (aka lattice energy) between charged ions in the ionic compound and hydrogen bonds between water molecules.
Water however, is not a good solvent for organic compounds and metals...
