The answer is below

Explanation:

Here some of the difference between aluminum phosphide and aluminum phosphate

1. Aluminum phosphide is a crystalline solid with either dark gray or yellow color. While Aluminum Phosphate is in a nanopowder form but with a whitish color.

2. Aluminum phosphide is used in the fumigation of plants, while Aluminum phosphate is used in cosmetics, paints, etc.

3. Aluminum phosphide has a compound formula of AlP with a molar mass of 57.9552 g/mol, while Aluminum Phosphate has a compound formula of AlO4P with a molar mass of 121.9529 g/mol

If the enthalpy value for a reaction is negative, what does that indicate about the reaction? Please explain how you got your an

Elis [28]

The answer is; D

Enthalpy is the system’s internal energy ( considering the product of its pressure and volume). When the enthalpy is negative, it means that the products have a lower energy level than the reactants - meaning the system has dispensed some energy into the environment.

Charra [1.4K]

Answer:

(a) The Lewis structure is shown in the image below.

(b) $CaF_2$

(c) Calcium loses 2 electrons to 2 atoms of fluorine and these 2 atoms of fluorine accepts each electron to form ionic bond.

(d) Calcium atom loses electrons.

Explanation:

Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or $1s^22s^22p^63s^23p^64s^2$

There are 2 valence electrons of Calcium.

Fluorine is the element of group 17 and second period. The electronic configuration of the element fluorine is - 2, 7 or $1s^22s^22p^5$

There is 1 valence electron of fluorine.

The Lewis structure is drawn in such a way that the octet of each atom is complete.

Thus, calcium loses 2 electrons to 2 atoms of fluorine and these 2 atoms of fluorine accepts each electron to form ionic bond. This is done in order that the octet of the atoms are complete and they become stable.

Thus, the formula of calcium chloride is $CaF_2$ .

(a) The Lewis structure is shown in the image below.

(b) $CaF_2$

(c) Calcium loses 2 electrons to 2 atoms of fluorine and these 2 atoms of fluorine accepts each electron to form ionic bond.

(d) Calcium atom loses electrons.
