Common insoluble (sparingly soluble) salts are carbonates, hydroxides<span>, sulfates, and sulfides.</span>
Answer:
The percentage of Lake Parsons which has evaporated since it became isolated is 68.24%.
Explanation:
The concentration of salt dissolved in Lake Parson = 21.0 g/L
= In 1 L of lake Parson water = 21.0 g of salt
The concentration of salt in several nearby non-isolated lakes = 6.67 g/L
The salt concentration in Lake Parsons before it became isolated = 6.67 g/L
In 1 L of lake water = 6.67 g of salt
If 1 L of lake Parson water has 6.67 g of salt. Then 21.0 grams of salt will be in ;
Water evaporated = 3.15 L - 1 L = 2.15 L
The percentage of Lake Parsons which has evaporated since it became isolated:
Answer:
La afirmación es verdadera.
Explanation:
El método científico es un método de investigación usado principalmente en la producción de conocimiento en las ciencias y se define como un procedimiento para tratar un conjunto de problemas. En ciencia, el método científico es la estrategia para la investigación y la exploración de lo desconocido.
Por lo que el método científico es el procedimiento mediante el cual es posible alcanzar un conocimiento objetivo de la realidad, tratando de dar respuesta a las interrogantes acerca del orden de la naturaleza.
Para ser científico, un método de investigación debe basarse en la empírica y en la medición, sujeto a los principios específicos de las pruebas de razonamiento.
El método científico se basa en la reproducibilidad, es decir, la capacidad de repetir un determinado experimento, en cualquier lugar y por cualquier persona, y la refutabilidad, es decir toda proposición científica tiene que ser susceptible de ser falsada o refutada.
Entonces <u><em>la afirmación es verdadera.</em></u>
Answer:
Option B:Publishing scientific journals
Explanation:
We are told that Lindsey is trying to gain credibility for her studies.
Since she completed her experiment and discussed her finding with colleagues, the most logical next step would be to publish scientific journals. This is because the other options given are not steps that should be taken because she has completed the research and therefore has no need to speak at a conference next nor even create new charts which they must have done during the research. No need for her to make sure the topic is popular.
Option B is correct
3 bc Hf is an element hafnium and HF is compound hydrogen flouride
