Answer:
B. No more powder will dissolve in the water.
Explanation:
If a lot of powder is added to the water, then a fully saturated solution would be created. This means that no matter how much more powder is added or how strong the mix is shaken, no more powder will disolve. The powder will instead remain in solid form in the solution.
Answer:
it would be redshift and cosmic background radiation
Answer:
1.0 L
Explanation:
Given data
- Initial volume (V₁): 0.35 L
- Initial concentration (C₁): 2.0 M
- Final concentration (C₂): 0.70 M
John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
V₂ = C₁ × V₁ / C₂
V₂ = 2.0 M × 0.35 L / 0.70 M
V₂ = 1.0 L
If you cut the cube and keep all the pieces you are causing only physical change
Transferring or sharing electrons between atoms forms a covalent bond.<span> Covalent
bonding is when atoms share electrons. It is a chemical bond that involves the
sharing of electron pairs. These pairs are called bonding pairs. Examples of
compounds that has covalent bonds are CO2, organic compounds, lipids and
proteins.</span>
