__Na3PO4 + __Sr(NO3)2 --> ___Sr3(PO4)2 + __NaNO3 If .0789 moles of Strontium Nitrate are reacted, how many moles of Sodium Phosphate were reacted?

0.0526mol

Explanation:

The chemical equation given in this equation is as follows:

Na3PO4 + Sr(NO3)2 → Sr3(PO4)2 + NaNO3

However, this equation is unbalanced as the number of atoms of each element on each side does not correlate. The balanced equation is as follows:

2Na3PO4 + 3Sr(NO3)2 → Sr3(PO4)2 + 6NaNO3

This balanced equation means that:

2 moles of Sodium Phosphate (Na3PO4) is required to react with 3 moles of Strontium Nitrate (Sr(NO3)2)

Hence, if 0.0789 moles of Strontium Nitrate are reacted, then 0.0789 × 2/3

moles of sodium phosphate will also react.

= 0.0789 × 2/3

= 0.1578/3

= 0.0526mol

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
