Answer:

the valence of S is -2. For FeS to be neutral the valence of Fe used must be +2

and since Iron (II) has its valency 2, FeS will be Iron (II) Sulfide.

How much heat is absorbed when 63.7 g H2O(l) at 100 degrees Celsius and 101.3kPa is converted to steam at 100

Alona [7]

Answer:

Q = 143,921 J = 143.9 kJ.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the absorbed heat by considering this is a process involving sensible heat associated to the vaporization of water, which is isothermic and isobaric; and thus, the heat of vaporization of water, with a value of about 2259.36 J/g, is used as shown below:

$Q=m*\Delta _{vap}H$

Thus, we plug in the mass and the aforementioned heat of vaporization of water to obtain the following:

$Q=63.7g*2259.36J/g\\\\Q=143,921J=143.9kJ$

Regards!

What type of ions do metals naturally form? Negative ions, by gaining electrons to fill the valence shell Negative ions, by losi

Mila [183]

Answer: Option (d) is the correct answer.

Explanation:

Metals are the species which contain more number of electrons.

When a specie loses electrons then it acquires a positive charge. Whereas when an atom gains electrons then it acquires a negative charge.

Thus, as metals have more number of electrons, therefore, in order to gain stability metals readily lose electrons.

Hence, metals naturally form positive ions, by losing electrons to empty the valence shell.
