Which element, when combined with Iodine, would most likely form an ionic compound?
uranmaximum [27]

In an ionic compound the atoms are linked via ionic bonds. These are formed by the transfer of electrons from one atom to the other. The atom that loses electrons gains a positive charge whereas the atom that accepts electrons gains a negative. This happens in accordance with the octet rule wherein each atom is surrounded by 8 electrons

In the given example:

The valence electron configuration of Iodine (I) = 5s²5p⁵

It needs only one electron to complete its octet.

In the given options:

K = 4s¹

C = 2s²2p²

Cl = 3s²3p⁵

P = 3s²3p³

Thus K can donate its valence electron to Iodine. As a result K, will gain a stable noble gas configuration of argon while iodine would gain an octet. This would also balance the charges as K⁺I⁻ creating a neutral molecule.

Ans: Potassium (K)

A scientific _______ is an explanation for how something occurs. It is supported by a great deal of evidence.
Minchanka [31]
Law, since "It is supported by a great deal of evidence. A theory is almost like an educated guess but a little more complex. Someone can have a theory and try to predict the outcome, which could be how they want it to go or how they don't want it to go. With a law, the scientist is basically certain of the outcome due to the evidence that was provided when the law was created.

The density of ammonia gas under certain conditions is 0.625 g/l. calculate its density in g/cm3.
MatroZZZ [7]
From the conversion of units:
1 cm^3 is equivalent to 1 mL
1 L is equivalent to 1000 mL
therefore,
to convert from liter to cm^3, we simply multiply by 1000.
Note that the multiplication will be done in the denominator.

Based on this:
density = (0.625 g/l) x (1g/1000 cm^3) = <span> 0.000625 g/cm^3 
            = 6.25 x 10^-4 g/cm^3</span>
