Answer : The chronological order events related to the formation of the universe with the stages in which they occurred are given below;
- Expansion from an infinitely hot point - Which is also called as the Planck era from which the big bang theory arrived. It is assumed that from the moment of initial expansion to
seconds afterwards, and many also refer that it was from an infinitely hot point. - Hydrogen fuses into helium - This was called as the era of Nucleosynthesis which resulted from the Fusion and it continued in the Era of Nucleosynthesis ( which is 0.001 seconds – 3 minutes)
- The first neutral atom begins to form - Era of atoms, it began in around 380,000 years – 1 billion years or so.

Answer:
Its right you dont have to change anything
Answer:
The answer to your question is: 0.05 M
Explanation:
I'm not sure about the units umol, I think is units mol.
Data
MgF2 = 0.0191 mol
Volume = 400 ml
Molarity = moles / volume
Molarity = 0.0191 / 0.4 l
Molarity = 0.048 ≈ 0.05 M
Answer:
answer A makes the most sense
Explanation:
it's the only one the describes measuring the acid in the air from a factory (humans) I may be wrong tho
First, we distinguish whether table sugar or table salt will be more soluble. The bonds between the molecules of the table sugar are weaker than the bonds between the molecules of salt. Therefore, it is easier for the sugar molecules to dissolve.
Next, we evaluate the effect of temperature on solubility. As the temperature of a solvent increases, it is able to hold more and more solute. This means that the sample with table sugar kept at the highest temperature will contain the most dissolved solute, and this is sample 1.
