Answer:
The charge of ions must be balance
Explanation:
Ionic compound: It is that compound which consist of positive and negative ions and ions held together by electrostatic force.Electric force is that force which act between two charges.
The compound is neutral because negative ions is equal to positive ions in the ionic compound.
The charge of ions must be balance.It is necessary condition for writing a formula for an ionic compound.
Hence,the charge of ions must be balance is that condition which must be met when writing a formula for an ionic compound.
Answer:
Saturn It is most well-known for its rings.
Neptune It has the strongest winds in the solar system.
Uranus its orbit was used to predict the existence of another planet.
Jupiter It has a giant storm three times the width of Earth.
Explanation:
<u>Properties of different planets</u>
Saturn is the second largest planet in the solar system and it’s most well-known for its bright and beautiful rings that circle its equator. These rings are composed of numerous ice and rock particles
Neptune has the strongest winds in the solar system and the winds are known for whipping the clouds at a speed of approximately 2000 Km/h
Astronomers used the orbit of Uranus to predict the existence of Neptune in 1846.
Jupiter has an iconic Great Red Spot just off the planet’s center which is approximately 1.3 times the Earth’s diameter and its winds move at a speed approximately 425 mph.
Unfortunately, to obtain the numerical value of the slope of the line using the given formula, 2 points must be given. Because of the lack of the given points however, let us just go through why the formula is like that. The given formula stated is: slope, m = (y2 - y1) / (x2 - x1). That is merely a two-point representation of the slope's definition, which is "rise over run".

It turns out that the star in question belongs to the K5V star class. Thus, the surface temperature of this must be between 5200 K and 3700 K. It has a surface temperature of 6200 K to 5200 K and is a G2V class star, commonly known as Bernard's star. In other words, the star in question has a colder surface than HIP 87937. This is further explained below.
<h3>What is surface temperature?</h3>
Generally, The temperature at a surface is referred to as the surface temperature. In particular, it may refer to the surface air temperature, which is the temperature of the air that is relatively close to the earth's surface.
In conclusion, The star in question is of the K5V type. Therefore, the temperature of the surface of this must be somewhere between 5200 and 3700 kelvin. The star with the designation HIP 87937, often known as Bernard's star, is of the G2V type. Stars of this type have a surface temperature that falls anywhere between 6200 and 5200 degrees Celsius. Therefore, it should come as no surprise that the surface temperature of the given star is lower than that of HIP 87937.
