Answer:
The answer is 0.023 moles of phosphorus
Explanation:
The 15-15-15 fertilizer is a fertilizer of great versatility, made with nitrogen, phosphorus and potassium, which makes it one of the fertilizers most used for fertilizer in the sowing plant, thus covering the crop requirements from planting. .
This fertilizer consists of 14.25% phosphorus pentoxide (P2O5). Therefore, we have to remove 14.25% at 10 grams of 15-15-15 fertilizer to calculate the moles of phosphorus. As follows:
Grams of P2O5 = 10 g x 0.1425 = 1.425 g
We calculate the molecular weight of phosphorus. We use the periodic table:
Phosphorus molecular weight = 2 x 30.97 = 61.94 g/mol
Now we calculate the moles of phosphorus in the fertilizer:
Phosphorus moles = 1,425 g/61.94 g/mol = 0.023 moles
Answer:
Sample Response: If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
Explanation:
its the sample response

Trihydrate - basically 3 molecules of water. Unless you're referring to the molecule 3H2O used in measuring the total body water in the case it tritiated water.
Answer:
The correct option is: C. tetrahedral, polar
Explanation:
Trifluoromethane, also known as Fluoroform, is a chemical compound with the molecular formula CHF₃.
Since three fluorine atoms and one hydrogen atom is bonded to the central carbon atom and there are zero lone pairs on the carbon atom. Therefore, the<em> molecular geometry and shape of CHF₃ is tetrahedral</em>.
As there are three carbon-fluorine polar bonds in CHF₃ molecule, thus there is a net dipole moment. <em>Therefore, CHF₃ is a polar molecule.</em>
