Answer:
A small amount of solute dissolved in a larger amount of solvent.
Take this analogy to help you understand, if you were to put a teaspoon of sugar in a liter of water it would dissolve, but if you put a sack of sugar in it it would not dissolve! The solute is what is being dissolved and the solvent is what dissolves the solute, so that eliminates some of the options.
Answer:
The hot water remains at the top of chilled water.
Explanation:
The hot water remains at the top of chilled water because hot water has less denser as compared to chilled water. Due to higher density of chilled water, it remains at the bottom due to its greater mass while on the other hand, the hot freshwater goes upward and spreads at the top of the chilled water due to lower mass so when the hot water is added to the chilled water, hot water remains at the top.
Element Symbol Atomic Mass
Barium Ba 137.327
Hydrogen H 1.00794
Oxygen O 15.9994
Hope this helps, good luck
La primera instrucción es verdadera, la segunda es falsa porque dos elementos no pueden tener el mismo número de masa (excepto azufre y argón) Estrictamente hablando, No. Puede tener 2 (o más) elementos con el mismo 'número de masa atómica', lo que significa que el número total de nucleones (neutrones de protones) es el mismo. En el ejemplo dado en una respuesta anterior, el azufre tiene un isótopo con el número de masa atómica 36 (16p 20n) y Argón también tiene un 36 (18p 18n). La tercera declaración es verdadera, si tiene un número diferente de neutrones, entonces es un isótopo. La cuarta declaración es falso. Espero que esto te ayude.
Answer:
The most dangerous area for animals and plants is the one that contains the greatest biodiversity on the planet: Southeast Asia. In this region are the five most affected countries in the world: Malaysia, Brunei, Singapore, Indonesia and Thailand. The Atlantic rainforests of Brazil are also very affected, this is due to the fact that great catastrophes have occurred in these places lately, such as the massive fire in the Amazon, and the floods that occurred after the tremendous absence of vegetation that these places suffered.
Explanation:
Also on the other hand, the regions with the highest extinction are those that carry out little environmental policies where care has not been taken for species that are in danger of extinction, as happens, for example, in those islands such as the Galapagos Islands, which are subject to severe fines for harm turtles.
