Ionic crystals are made from ions that are bonded together by ionic bonds. An example is salt crystals that are made of sodium and chloride ions.
Explanation:
An ionic bond is formed when one atom donates electrons to another atom so they both attain stable electron configuration. The two atoms are then bound by their acquired charges. For example sodium atom2.8.1) donates its valence electrons to chlorine atom (2.8.7). They both achieve stable electron configuration of 2.8 and 2.8,8 respectively. Because sodium ion will now have a positive charge (because it has more protons than electrons) and chloride ion will have a negative charge because it has more electrons than protons, the two are bonded together electrostatically forming ionic bonds.

Answer:
REFRACTION IS THE BENDING OF A WAVE AS IT PASSES AT AN ANGLE FROM ONE MEDIUM TO ANOTHER. WHEN A WAVE MOVES FROM ONE MEDIUM TO ANOTHER, THE WAVE'S SPEED CHANGES. WHEN A WAVE ENTERS A NEW MEDIUM AT AN ANGLE, THE PART OF THE WAVE THAT ENTERS FIRST BEGINS TRAVELING AT A DIFFERENT SPEED FROM THE REST OF THE WAVE.
Explanation:
Answer:
Keq = [CO][Cl₂]/[COCl₂].
Explanation:
For the balanced reaction:
COCl₂(g) ⇄ CO(g) + Cl₂(g).
The equilibrium constant can be expressed as concentration equilibrium constant (Kc) or pressure equilibrium constant (Kp).
The equilibrium constant is the ratio of the product of products concentrations to the product of the reactants concentrations.
Keq = [CO][Cl₂]/[COCl].
Answer:Boron
Explanation:
it is element 5 represented by the letter B
Across:
10. The circulatory system transfers nutrients, gases, liquids, and heat around the body.
11. The circulatory system transports heat, which helps regulate temperature.
13. The place where oxygen enters the blood and carbon dioxide leaves the blood. Lungs.
15. A gas that is transported in arteries from the lungs to the rest of the body via the heart. Oxygen.
Down:
2. The heart, blood, and vessels. Circulatory System.
4. Blood in arteries is bright red because it is rich in oxygen.
6. A waste gas that is transported in veins from the body to the lungs via the heart. Carbon di Oxide.
<u>Explanation:</u>
The circulatory system includes blood vessels, blood, and heart. This system provides the body tissues with oxygen and some nutrients. It also carries hormones and eliminates needless waste products.
This transportation takes place between the cells via blood throughout the body. The channel that blood passes through is a blood vessel that is pumped by an organ called heart. The heart directs the blood passing all over the body.
The lungs are a duo of air-filled, spongy organs positioned on both sides of a human's chest. Its main function is to take in air present in the atmosphere and transfer oxygen to the bloodstream. From where it gets circulated throughout the body.
