What i would say: The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Hope this helps! :)
Answer:
Na₂CO₃•H₂O
Explanation:
After it is heated, the remaining mass is the mass of sodium carbonate.
30.2 g Na₂CO₃
Mass is conserved, so the difference is the mass of the water:
35.4 g − 30.2 g = 5.2 g H₂O
Convert masses to moles:
30.2 g Na₂CO₃ × (1 mol Na₂CO₃ / 106 g Na₂CO₃) = 0.285 mol Na₂CO₃
5.2 g H₂O × (1 mol H₂O / 18.0 g H₂O) = 0.289 mol H₂O
Normalize by dividing by the smallest:
0.285 / 0.285 = 1.00 mol Na₂CO₃
0.289 / 0.285 = 1.01 mol H₂O
The ratio is approximately 1:1. So the formula of the hydrate is Na₂CO₃•H₂O.
A. Fireworks exploding is the answer
Are there choices? Because if there are that would help A LOT, but if there are no choices I can give some examples of physical properties, though there are MILLIONS, here are a few :) .
Physical property examples are: color, smell, freezing point, boiling point, melting point, attraction or repulsion to magnets and viscosity and density. If these are not options, please let me know :)
Have a great day, let me know if I can help with anything else, have a great day, and, if you have time, mark brainiest, I would really appreciate it, thanks! :D
It will received an H+. I’m not sure if that answers your question correctly
