Answer: Star formation begins when the denser parts of the cloud core collapse under their own weight/gravity. These cores typically have masses around 104 solar masses in the form of gas and dust. The cores are denser than the outer cloud, so they collapse first.
Hope this helped! :))
The volume of the given solution is 2.5 L.
<u>Explanation:</u>
Volume of the solution = 2500 mL
We have to convert it into litres as,
1000 mL = 1 litre
To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.
Here given volume is 2500 mL.
Volume in L = 
= 2.5 L
So the volume of the solution is 2.5 L.
N = given mass/ molar mass.
n = number of moles
given mass = 2.47 g
molar mass = 197 g/mol
n = 2.47 / 197
n = 0.01253 moles.
I'm sure you wanted to ask more than this. Just put some comments in. I can do the same.
Answer:
Electrolyte
Explanation:
A compound that conducts electricity when dissolved in water would most likely be classified as electrolyte.
The ionic compound in solid form do not conduct the electricity but when dissolve in water they separated into ions and have ability to conduct the electricity because of mobile ions that move freely and allow the charge to flow.
The ionic compounds are called electrolyte and electrolyte solution is formed when they dissolve in water.
For example when sodium chloride is placed into water it split into ions and conduct electricity because of mobile ions.
Chemical equation:
NaCl → Na⁺ + Cl⁻
