How much heat is required to raise the temperature of 18 grams of liquid water by 25 C?

1 answer:

3 0

Since the molecular weight of water is about 18 g/mol, you have about 1 mol of water. So, now we know that it takes approximately 46.2 kJ of heat energy to warm 18.02g of water from 25C to 100C and then to vaporize it into steam. Hopefully this helped!

Which type of element is not likely to react chemically with other elements to form a compound?

blsea [12.9K]

Answer:

The noble gases with complete outermost shell electrons.

Explanation:

Noble gases or inert gases do not react chemically with other elements because they have a complete configuration of their electronic shells. What drives chemical reaction is simply the exchange of electrons between two or more atoms. It can be a loss, a gain or simple sharing of electrons in order to achieve a complete configuration just like those of noble gases.
