Explain why calcium (Ca) has a greater atomic radius than magnesium (Mg).

Chemistry
1 answer:
g100num [7]2 years ago
8 0

Answer:

Magnesium nucleus will attract the electrons more toward it and therefore, shrinking the size of the atom. Magnesium atom is smaller than Calcium atom because Calcium has more electron ( 20e− ) which will occupy more energy levels ( n=4 for Calcium versus n=3 for Magnesium)

What is the Lewis dot structure for the formula ch3br?
Alenkasestr [34]

You may find the Lewis dot structure of the CH₃-Br in the attached picture.

Explanation:

In the Lewis dot structure we represent the unpaired electrons using dots.

Bromide have one electron shared with one electron from the carbon to form a covalent bond, while the remaining electrons remains unpaired. We represent the six unpaired electrons of the bromide with dots.

The coordination sphere of a complex consists of ________. The coordination sphere of a complex consists of ________. the ligand
sammy [17]

Answer:

The coordination sphere of a complex consists of <u><em>the central metal ion and the ligands bonded to it.</em></u>

Explanation:

The Coordination Compounds are sets of a central metal ion attached to a group of molecules or ions that surround it. They are also called metal complexes or simply complexes. Then they are compounds that have a central atom surrounded by a group of molecules or ions, the latter called ligands.

The central atom must have empty orbitals capable of accepting pairs of electrons, with the transition metals being the ones with the greatest tendency. Because of this, they can act as Lewis acids (electron pair acceptors). The ligands have unshared electron pairs, then acting as Lewis bases (electron pair donors).

When forming a complex, it is said that the ligands coordinate to the metal and the central metal and the ligands attached to it constitute the coordination sphere of the complex.

Finally, <u><em>the coordination sphere of a complex consists of the central metal ion and the ligands bonded to it.</em></u>

2. The Density of Water is 1.0000g/cm3. Based on this property of water,
Vanyuwa [196]

Answer:

if the object sank then that object has a greater density then water. if the object floated then its density is lower then water.

Explanation:

lets say object 1 has a density of 24/cm3. the density is greater then water (1.0000g/cm3) so it would sink. now lets say object 2 has a density of 0.79383g/cm3 since it's less then the density of water (1.0000g/cm3) it would float.

The calvin cycle and the krebs are referred to as cycles of chemical reactions because they
Schach [20]

Answer:

The options are

a. occur inside organelles. b. start over continually. c. are part of the carbon cycle. d. allow energy to flow in ecosystems.

The answer is b. Start over continually

Explanation:

The two cycles involves a continuous process as long as the reactants are present under suitable conditions. The cycle happens all the time due to it being necessary to produce important products all the time for the body system.

A good example involves the existing Carbon dioxide and water reacting together to get converted into substance that could provide energy (ATP and NADH) such as Glucose.
