Chemistry developed from alchemy after the 1700s. It was the Alchemist <span>observations and accidental discoveries that brought around modern chemistry.</span>
Answer:
universal mass unit
<h2 />
The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
Sodium belongs to Group 1A. It means that sodium has 1 valence electron. It needs to complete its octet electron or have the same configuration of a noble gas to become a stable ion. It would likely to release 1 electron to complete its octet than accept 7 more. Therefore, its ion form would be Na+.
<h3>What's Electronic configuration?</h3>
- The arrangement of an snippet's or patch's( or other physical structure's) electrons in their infinitesimal or molecular orbitals is known as the electron configuration in infinitesimal drugs and amount chemistry.
- For case, the neon grain's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, singly, are present in each of the 1s, 2s, and 2psubshells.
- According to electronic configurations, each electron moves collectively within an orbital while being girdled by an average field produced by all other orbitals.
- Slater determinants or configuration state functions are used to mathematically describe configurations.
<h3>What part does electronic configuration play?</h3>
- The chemical responses that an snippet can engage in as well as the types of motes that tittles can combine into to produce more complex composites depend on the electrical configuration of the snippet.

Porque es Clara y no contiene quimicos
The percentage error that would be introduced in a 35.0 mL sample of liquid is 2.86%
<h3>Data obatined from the question</h3>
From the question given, the following data were obtained:
- Absolute error = 1 mL
- True measurement = 35 mL
- Perecentage error =?
<h3>How to determine the percentage error</h3>
The percentage error that would be introduced can be obtained as illustrated below:
Percentage error = (Absolute error / True measurement) × 100
Percentage error = (1 / 35) × 100
Percentage error = 2.86%
Thus, percentage error that would be introduced is 2.86%
