Answer: Each trial was repeated several times during the experiment.
A scientific design refers to a scientific plan or methodology, which needs to be followed to perform a experiment so as to obtain accurate and appropriate result matching with the situation of the hypothesis. Each trial was repeated several times during the experiment best describes an experiment that had a good scientific design because trials in an experiment brings either concordant or consistent results or inconsistent results. The concordant results suggests that the methodology applied is correct, and inconsistent results show that methodology applied is incorrect.
A.
Because no more heat is being added to the system
Answer:
not 100% sure but I think it's unbalanced chemical
Answer:
The three definitions are listed in the explanation.
Explanation:
A nonelectrolyte is a molecular compound that does not consist of ions hence it does not dissociate into ions in solution.
A weak electrolyte is a soluble ionic compound that dissociates only to very small extent into ions in solution.
A strong electrolyte is a soluble ionic compound that dissociates completely into ions when dissolved in water.
Limestone is easily weathered by acid rain. When rain mixes with gases such as sulfur dioxide and carbon dioxide in the atmosphere, acid rain is formed (sulfuric acid and carbonic acid respectively). When the rain precipitates and meets with limestone which is CaCO3, it is weathered a shown by the formulae; 2CaCO₃ (s) + H₂CO₃ → 2CaHCO3 (aq)
Geographical features formed as a result of weathering of limestone in rocks are caves, stalactites, and stalagmites.
