Answer:
The answer is D
Explanation:
Ionic compounds have high melting and boiling points.They can dissolve in water.And they donot form crystal structurs by dissolving.And they donot conduct electricity.
Table salt (an ionic compound) forms crystal structures, similar to other ionic compounds, due to the strong electrostatic forces holding its ions in a well-organized lattice. So the correct option is C.
The property of table salt, which is also a property of other ionic compounds, is that it forms crystal structures. Table salt, like all ionic solids, exhibits a crystalline structure because its ions are held together by strong electrostatic forces of attraction in a rigid and well-organized lattice. In contrast, ionic compounds typically have high melting points, dissolve in water, and can conduct electricity when dissolved or molten because ions are free to move, allowing for the flow of electric charge.

Answer:
Gaining electrons
Explanation:
Anions are negatively charged ions.
When an atom gains some electrons then anions are formed.
As electrons are negatively charged so anions are also negatively charged ions.
Anions are attracted by the cathode which is positively charged electrode.
An anion is formed by the gain of one or more electrons to the atom.
The total pressure exerted by a person when he stands on both the feet is 10000000 Pascals
Explanation:
Given data
Weight of the person= 500 N
Area of the foot= 0.5 m ²/ 100 ×100
To find the pressure exerted we have the formula,
Pressure exerted= force/area
Pressure exerted= 500 ×100×100/0.5
Pressure exerted=10000000 Pascals
The total pressure exerted by a person when he stands on both the feet is 10000000 Pascals
Speed of Dayshawn travelling towards his home is 12 m/s
Speed of her mom towards his school is 5 m/s
They both starts at same time so whenever they will meet on their path the sum of the distance covered by Dayshawn and distance covered by his mom must be equal to the total distance of school and home
Now let say they both meet after "t" time when they starts motion
so we can write the total distance between school and home as
here d = 6492 m
= speed of dayshawn
= speed of his mom
now by solving the above equation
so they will meet after 381.9 s from start which will be 3.36 minutes from there start
Also at this time the distance covered by her mom will be
so they will meet at distance 1909.4 m from their home
