Answer:
0.66g/mL
Explanation:
La densidad es una propiedad de la materia definida como la masa de una sustancia en un determinado volumen.
En este problema, podemos hallar la densidad sabiendo que la diferencia de masas del pic vacío y el pic lleno es la masa de la solución y que el volumen que ocupa es de 25mL:
<em>Masa solución:</em>
25g - 8.5g = 16.5g
Así, la densidad será:
16.5g / 25mL =
<h3>0.66g/mL</h3>
Answer: Option D
Explanation:
Chemotrophs can be defined as the organism which has the ability to get energy by the oxidation of electron donors present in the nearby environments.
These molecules in the environment can be organic or inorganic.These bacteria are usually called as thiobacillus denitrificans.
These bacteria reduce the nitrate into nitrite and the energy source for these bacteria is thiosulfate(sulfur).
Answer:
Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. This happens because fluid pressure increases with depth. According to Archimedes' Principle, the buoyant force on a submerged object is equal to the weight of the liquid displaced by the object.
