Formula of sodium phosphate = Na₃PO₄
So, one mole of sodium phosphate molecules have 3 moles of Na atoms
Then, 1.6 moles of Na₃PO₄ will have: 1.6 × 3 = 4.8 moles of sodium atoms will be present
5CO2
5x2=10
10 atoms of oxygen
They are different because of the number of electrons and protons and heir composition
Both California and Peru have or have had significant gold deposits because of their proximity to where two tectonic plate boundaries meet. Off the California coast there is the Pacific Plate and the North American Plate which meet at the San Andreas Fault but there also is the Farallon Plate which apparently has subducted somewhat below the North American Plate. Off Peru, the Nazca Plate is subducting under the South American Plate and which has caused the Andean orogeny.
Answer:
26.5°C
Explanation:
Heat added is the product of mass, specific heat capacity, and change in temperature.
q = mC(T − T₀)
25.7 cal = (18.4 g) (0.215 cal/g/°C) (T − 20.0°C)
T = 26.5°C
