Answer:

The weight of 3.45 moles of carbon dioxide has been 151.8 grams.

Moles can be calculated as the mass of solute present with respect to the molecular mass of the solute.

Moles can be expressed as:

Moles = \rm \dfrac{weight}{molecular\;weight}

molecularweight

weight

The molecular weight of carbon dioxide has been 44 grams/mol.

The given moles of carbon dioxide = 3.45 moles.

3.45 mol = \rm \dfrac{weight}{44\;g/mol}

44g/mol

weight

Weight of carbon dioxide = 3.45 \times× 44 grams

Weight of carbon dioxide = 151.8 grams.

The weight of 3.45 moles of carbon dioxide has been 151.8 grams.

To find grams from moles, multiply moles by molar mass of CO2,
The molar mass of CO2 is 12.01+32=44.01g CO2
Multiply 3.45 mol*44.01 and you will get 151.8g CO2

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)
