Explanation:
( A P E X )
Answer:
B. calcium has electrons in more energy levels than magnesium
Explanation:
atoms are made of three types of subatomic particles - electrons, protons and neutrons.
Neutrons and protons reside in the nucleus of the atom and electrons reside in energy shells
electronic configuration for both Ca and Mg are as follows
Mg - 2,8,2
Ca - 2,8,8,2
outermost energy shell of Mg with electrons is the third energy level
whereas outermost energy shell of Ca with electrons is the fourth energy shell
therefore Ca has a larger atomic radius than Mg as it has one more energy shell than Mg in which electrons reside
Answer:
a) 
b) 
c) 
Explanation:
Hello,
a) In this case, the given height in cm is:
And the radius in cm is:
Thus, the volume in cubic centimeters which is also equal in mL (1cm³=mL) is:
b) In this case, the given height in mm is:
And the radius in mm is:
Thus, the volume in cubic millimeters is:
c) Finally, since 1000 mL equal 1 L, the required density in g/L turns out:
Best regards.
The correct answer is option 2. A 0.8 M aqueous solution of NaCl has a higher boiling point and a lower freezing point than a 0.1 M aqueous solution of NaCl. This is explained by the colligative properties of solutions. For the two properties mentioned, the equation for the calculation of the depression and the elevation is expressed as: ΔT = -Km and <span>ΔT = Km, respectively. As we can see, concentration and the change in the property has a direct relationship.</span>
11- Form of energy that can be reflected or emitted from objects through electrical or magnetic waves.
12-Energy that is caused by moving electric charges.
13-Energy stored in the bonds of chemical compounds.
I only know those. Sorry hoped I helped a little! :)
