<u>Answer:</u> The mass of sulfur trixoide is 0.0485 g
<u>Explanation:</u>
We are given:
Molecules of sulfur trixoide =
According to mole concept:
number of molecules are present in 1 mole of a compound
So, number of molecules will be present in =
To calculate the number of moles, we use the equation:
Moles of sulfur trixoide =
Molar mass of sulfur trioxide = 80 g/mol
Putting values in above equation, we get:
Hence, the mass of sulfur trixoide is 0.0485 g
Answer:
It is important because it separates the area that the process is happening from its surroundings, and it's easy to measure and make observations by doing that.
Explanation:
The system is the part of the universe that is separated for study. It has a frontier, which is the limitation of it, and the external area is the surroundings.
In the system the chemical and physical process is happening: reactions are taking place, gas is expanding, heat is being absorbed or lost, etc.
So, to understand the process that is happening, it's necessary to define the system under study because the measurements, analyze, and observation will be easily done.
Chemistry is the basic building block of all things in this world, living and nonliving. All things in this world roots back to the chemistry or science of things. From the arrangement of the molecules, to their interactions with each other, resulting to their ow characteristics and properties. These properties are what we interact with in our everyday life.
Answer:
1.878g
Explanation:
Volume = 30.0ml
Density = 0.626gcm−3
Mass = ?
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³ so density = 0.626g/ml
The relationship between all three parameters is given by the equationn below;
Mass = Density * Volume
Mass = 0.626g/ml * 30 = 1.878g
Answer:
Option A, The organism experiences a disruption in homeostasis.
Explanation:
When a pathogen enters the organism’s body, it disrupts its homeostasis. There are several receptors in the body that are responsible for maintaining the stability of the body through negative feedback loop.
A foreign element attaches to the surface of these receptors and hence disrupts their attachment with the probable substance necessary for the regulation of essential body function.
Thus, the temperature regulation get s impaired, hormonal imbalances occur, feeding system disturbs etc.
Hence, option A is correct
