Consider the balanced reaction

Chemistry
1 answer:

Answer:

561 g P₂O₃

Explanation:

To find the mass of P₂O₃, you need to (1) convert moles H₃PO₃ to moles P₂O₃ (via mole-to-mole ratio from equation coefficients) and then (2) convert moles P₂O₃ to grams P₂O₃ (via molar mass). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The final answer should have 3 sig figs to match the amount of sig figs in the given value.

Atomic Mass (P): 30.974 g/mol

Atomic Mass (O): 15.998 g/mol

Molar Mass (P₂O₃): 2(30.974 g/mol) + 3(15.998 g/mol)

Molar Mass (P₂O₃): 109.942 g/mol

1 P₂O₃ + 3 H₂O -----> 2 H₃PO₃

10.2 moles H₃PO₃            1 mole P₂O₃              109.942 g
----------------------------  x  --------------------------  x  -------------------  =  561 g P₂O₃
                                        2 moles H₃PO₃              1 mole

What is the difference between a conductor and an insulator?
Zielflug [23.3K]
A conductor is what helps heat or electricity pass through an object. Examples of conductors are, silver, iron, aluminum, etc..

An insulator does the opposite and instead, stops either from going through. Examples of an insulator is paper, wood, rubber, etc.

Can someone please help me with this? I would appreciate it.
Luba_88 [7]

Answer: State

Explanation:

The rock on the left is more shiny than the right, so that’s incorrect.

The rocks are not the same color, so that’s also incorrect.

Even though you can’t feel the textures, the right rock looks grainy and the left on doesn’t.

They both are solid, so that is the correct answer.
