Answer:
Filtración
Explanation:
Cuando se filtra una mezcla de arena y agua, la vermiculita se queda en el papel de filtro y el agua gotea. Como un filtro de café.
The reaction of acid, assuming HCl and calcium carbonate always produces a gas. The reaction is as follows:
2 HCl + CaCO3 --> CaCl2 + H2CO3
H2CO3, carbonic acid, is a weak acid that is unstable in water solutions at high concentrations. As such, it decomposes:
H2CO3 --> H2O + CO2
Then,
2 HCl + CaCO3 --> CaCl2 + H2O + CO2
The total ionic equation looks as follows:
2H+(aq) + 2 Cl-(aq) + CaCO3(s) --> Ca+2(aq) + 2 Cl-(aq) + H2O(l) + CO2(g)
Clearly, Cl- is a spectator ion as it is unchanged in the reaction. The net ionic reaction looks as follows:
2 H+(aq) + CaCO3(s) --> Ca+2(aq) + H2O(l) + CO2(g)
Answer:
A variable shape that adapts to fit its container.
Answer:
A
Explanation:
Would you base your career options using science?
Would you base your moral behavior on science? Science is notorious for not being able to answer moral questions.
Would you base the "meaning of life" on science? The meaning of life is hardly a question that the periodic table could answer.
The only option left is plant growth which science could answer.
