Answer: A. It is made of polar molecules.
Explanation:
A polar molecule refers to a molecule that has a covalent bond but has an uneven distribution of electrons due to an atom in the molecule having strong electronegativity which will attract more of the electrons from the other atom.
Water is such a molecule because Oxygen has strong electronegativity which leads to electrons being pulled to it.
Answer : The volume of produced at standard conditions of temperature and pressure is 0.2422 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = (740-22.4) torr = 717.6 torr
= final pressure of gas at STP= 760 torr
= initial volume of gas = 280 mL
= final volume of gas at STP = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Therefore, the volume of produced at standard conditions of temperature and pressure is 0.2422 L
Chemical reactions that release energy will not occur without a source of energy. So the answer is release.
The answer is B) gain 8 electrons
