Systematic or Random Error? -This type of error affects overall accuracy but does not necessarily affect precision. This type of
love history [14]

Answer:

<em>This type of error affects overall accuracy but does not necessarily affect precision.</em> - Systematic error

<em>This type of error affects precision but does not necessarily affect overall accuracy.</em> - Random error

<em>This type of error occurs if you use a buret that was calibrated incorrectly when it was made.</em> - Systematic error

<em>You can minimize this type of error by taking repeated measurements.</em> - Random error

Explanation:

<em>Systematic errors are errors that are attributable to instrument being used during measurement or consistent incorrect measurement during a research</em>. They are consistently and repeatedly committed during measurements and therefore affect the overall accuracy of measurements. A person committing systematic error can have precise repeated measurement but will be far from being accurate.

R<em>andom errors on the other hand has no pattern and are usually unavoidable because they cannot be predicted.</em> When sufficient replicate measurements are made, such errors are reduced to the barest minimum and usually do not affect the overall accuracy of measurements.

When sodium bonds with chlorine, what is the chlorine electron configuration like?A. any other halogenB. neonC. argonD. radon
Vika [28.1K]

Answer:

C

Explanation:

For sodium to bond with chlorine, it is through electrovalent bonding.

It means , one electron is transferred from the sodium to the chlorine.

Normally, chlorine has 17 electrons, by adding one , we get 18 electrons.

This is the number of electrons for Argon

Which compound would you expect to have greater surface tension, acetone [(ch3)2co] or water (h2o) ?
kenny6666 [7]

Surface tension increases by increasing the intermolecular forces.

<h3>What is intermolecular forces?</h3>

The electromagnetic forces of attraction or repulsion that act between atoms and other types of nearby particles, such as atoms or ions, are examples of intermolecular forces (IMFs), also known as secondary forces.

Between molecules, intermolecular forces are at work. In contrast, molecules themselves exert intramolecular pressures. In comparison to intramolecular forces, intermolecular forces are weaker. Intermolecular forces include things like the London dispersion force, dipole-dipole interaction, ion-dipole interaction, and van der Waals forces.

Intermolecular forces come in five flavors: ion-induced dipole forces, dipole-induced dipole forces, induced dipole forces, and dipole-dipole forces. Ions and polar (dipole) molecules are held together by ion-dipole forces.
