When waves bounce back after meeting a surface, it is called Reflection.
Answer:
loses one or more electrons from its valence shell
Explanation:
The answer is b because Heating water makes it evaporate faster
Adding salt makes it boil at a higher temperature
Increasing the pressure would force the water from the air back into the beaker
Increasing the humidity means there are more molecules in the air, increasing the chance that our water
Answer:
It will be produced 1 mol of H₃PO₄
Explanation:
The reaction is this one:
P₄O₁₀ + 6H₂O → 4H₃PO₄
Molar mass of P₄O₁₀ = 283.88 g/m
Mol = Mass / Molar mass
Mol = 71 g / 283.88 g/m = 0.250 mol of P₄O₁₀
Ratio is 1:4 so 1 mol of P₄O₁₀ will produce 4 moles of phosphoric in the reaction.
0.250 mol of P₄O₁₀ will produce 1 mol of H₃PO₄ (0.250 .4)
Answer:
It can't be broken and it can be moved
