Answer:
The correct answer is number 2. Elliptical, Spiral, Irregular.
Explanation:
Unfortunately, you did not attach the passage. Without the passage, we do not know what its content is.
So we are going to answer this question with our own knowledge.
The types of galaxies by their ability to form new stars, from most to least activity are "Elliptical, Spiral, Irregular."
That is the way astronomers classify galaxies in scientific terms. These scientists consider that the smallest galaxies or dwarf galaxies have approximately 100 million stars. On the other hand, giant galaxies have billions or trillions of stars. That immense is our universe.
Scientists still studying the universe and the galaxies to understand the way galaxies are formed.
To find the amount of moles in a molecule you divide the grams of the substance by the molar mass.
molar mass of CO2 = 44.01 g
22g / 44.01 = 0.50 moles CO2
Answer:
Se pueden separar dos líquidos inmiscibles, aceite y agua, mediante el uso de un embudo de separación. La mezcla de aceite y agua forma dos capas separadas porque son completamente insolubles entre sí. El aceite forma la capa superior mientras que el agua forma la inferior.

<span>Knowledge of the physicochemical properties of potential chemical alternatives is a requirement of the alternatives assessment process for two reasons. First, the inherent hazard of a chemical, such as its capacity to interfere with normal biological processes, and its physical hazards and environmental fate (degradation, persistence) are determined by its intrinsic physicochemical properties and the system with which it is interacting. For organic and inorganic chemicals, these intrinsic properties are determined by molecular structure, while for materials, they are determined by composition, size, structure, and morphology. Second, physicochemical properties can be used to eliminate from consideration chemicals that are likely to exhibit particular physical or toxicological hazards. As important as these data are, obtaining them is relatively fast and inexpensive, and can be readily done at the initial stages of the alternatives assessment.</span>
