sergiy2304 [10]

Answer:

All of the statements above are true.

Explanation:

Ice is solid water. Ice consists of an array of water molecules arranged into a crystal lattice. Ice has spaces between the water molecules so it is less dense than liquid water. Ice is about 9% less dense than liquid water. This accounts for the fact that it floats on water.

Ice contains more hydrogen bonds per water molecule when compared to liquid water.

Consider the balanced reaction
Scorpion4ik [409]

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
