Why is atomic radi measured using the nuclues from 2 of the same atoms

Chemistry

irina1246 [14]3 years ago
3 0

Explanation:

Atomic radii is measured using the distance between nucleus of 2 atoms rather than the distance between the nucleus and outermost shell because:

- There is no clear/sharp boundary of the orbital. This is why it is called an electron cloud.

- Also, the exact location of the electron is not known. What is known is the probability of finding the electron there.

Due to this, it is not possible to measure the atomic radii precisely. That's why the distance between the nucleus of two atoms is used.

For the mineral torbernite, Cu(UO2)2(PO4)2⋅8H2O, determine the ratio, by number, of H atoms to O atoms
astra-53 [7]
H:O = 4:5; (UO₂)₂ = 4 O atoms; (PO₄)₂ = 8 O atoms: 8H₂O = 16 H atoms + 8 O atoms; Total = 16 H atoms + 20 O atoms; H:O = 16:20 = 4:5

alisha [4.7K]

The scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.

Scientific equipments have been defined as the instruments and glassware that has been used in the scientific study and experimentation.

<h3>Equipments for heating the water</h3>

The water has been heated to the temperature of 85 degrees Celsius. The temperature has to be monitored thus, a thermometer has been used.

The water has been measured to be 1 L, thus the graduated cylinder, and beaker has been used for the measurement and heating of water.

The heat has been provided to the beaker by placing it on a hot plate.

Thus, the scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.

A polar commercial antacid contains both Al(OH)3 and Mg(OH)2. Are these compounds Arrhenius bases, Brønsted-Lowry based, or both
seropon [69]

Answer:

Magnesium hydroxide, Mg(OH)2, is an Arrhenius base and therefore also a Brønsted-Lowry base.

However, water can also act as a base by accepting a proton from an acid to become its conjugate base, H3O+. where Al(OH)3 is acting as a Lewis Base.

Explanation:

Arrhenius acids and bases

An Arrhenius acid is any species that increases the concentration of H+start text, H, end text, start superscript, plus, end superscript in aqueous solution.

An Arrhenius base is any species that increases the concentration of OH−start text, O, H, end text, start superscript, minus, end superscript in aqueous solution.
