Answer:
(C) PCl₅
Explanation:
(A) AlCl₄⁻
The central atom has 4 bond pairs and 0 lone pair. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
(B) NH₃
The central atom has 3 bond pairs and 1 lone pair. Hybridization is sp³. The geometry is pyramidal which has an angle of approximately 107.5°.
(C) PCl₅
The central atom has 5 bond pairs and 0 lone pair. Hybridization is sp³d². The geometry is trigonal bipyramidal in which the equatorial bonds has an angle of 120° and axial bond has an angle of 90°.
(D) CO₂
The central atom has 4 bond pairs and 0 lone pair. Hybridization is sp. The geometry is linear which has an angle of 180°.
(E) H₂O
The central atom has 2 bond pairs and 2 lone pairs. Hybridization is sp³. The geometry is bent shape which has an angle of approximately 105.5°.
1)Delta H=(Delta H of reactants)-(Delta H of products)
2)And we know CO have 3 bond CO and CO2 have 2 bond that each of them are 2 bond, please see the picture!
so lets answer it:
![(3 \times 358) + (2 \times 463) - (4 \times 358) - 436 = 132](https://tex.z-dn.net/?f=%283%20%5Ctimes%20358%29%20%2B%20%282%20%5Ctimes%20463%29%20-%20%284%20%5Ctimes%20358%29%20-%20436%20%3D%20132)
Sulfur is most likely to form covalent bond with oxygen.
The chemical formula would dictate how many ions are present in a solution. It tells how many of what ion would dissociate in the solution. In every chemical reaction or dissociation reaction, it is important to remember that the number of each atoms on each side would be equal.
The number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)
In order to determine volume (number of liters) one can make from 470 milligrams of table salt (NaCl)
First, we will convert the unit of concentration to grams per liter or grams per milliliter
From the question, the desired concentration is 0.90% NaCl (9 grams of salt per 1000 grams of solution)
Since the density of the NaCl solution is 1.0 g solution/mL solution, then
9 grams of salt per 1000 grams of solution means 9 grams of salt per 1000 mL of solution.
From the question, mass of the table salt = 470 milligrams = (470/1000) grams
∴ Mass of the table salt = 0.47 grams
Now,
If there are 9 grams of salt per 1000 mL of solution
Then, there will be 0.47 grams per
mL of solution
∴
mL
mL
mL
mL
∴ There will be 0.47 grams per 52.22 mL of solution
Hence, the number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)
