Answer:
The building block that makes up all matter in the universe is atoms.
The answer is:
2.5 moles
The explanation:
when avogadro's number = 6.02 * 10^23
and when 1 mole of the sample will give → 6.02*10^23 atoms
So, ??? mole of the sample will give→ 1.52 x 10^24 atoms
∴ number of moles = (1.52 X 10^24) * 1 mole / (6.02X10^23)
= 2.5 moles
5.18mL i hope this helps i hope this does to!
Answer:
- Both accurate and precise.
Explanation:
The experimental data is characterized as the data that is generated through a specific test or measurement with the purpose of analysis or evaluation. As per the question, the minuteness of the given data(29.27, 29.32, and 29. 27)most aptly describes that the experimental data collected by the student possesses 'accuracy and precision' apt and specific. It would yield the most worthy and reliable conclusion.
Answer is: color.
Chemical reaction of dissociation of sodium chloride in water:
NaCl(aq) → Na⁺(aq) + Cl⁻(aq).
Small quantities of water are colorless, solution of sodium chloride is also colorless.
Adding sodium chloride to water change water melting and boiling points.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
