Why it is important to have balanced charges when forming ionic compounds?
✿[tex]\textbf{Answer:-}[/tex]
As we know electrons can neither be created not destroyed,instead it can be transferred from one medium to another, therefore it is important to have balanced charges when forming ionic compounds. Net ionic equations must be balanced by both mass and charge. Also, the total number of electrons lost by the cationic species must be same with the total number of electrons gained by the anionic species.✿[tex]\textbf{More to know:-}[/tex]
Ionic Compounds-Ionic compounds are solids and hard due to the strong attracting force between the positive and negative ions. These compounds are generally brittle and break into pieces on application of pressure.Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero.What is the name of this alkene?

Facts about radiation in the human body
Answer:
How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
Because radiation kills rapidly dividing cells (which is why we use it to treat fast-growing cancer cells), radiation exposure most increases the risk of cancers of rapidly dividing cells — leading to leukemia, lymphoma, breast cancer, bladder cancer, colon cancer, liver cancer, lung cancer, esophageal cancer, ovarian

Which of the following statements is correct regarding the speed and velocity of an object? A. An object’s speed is determined by the distance the object traveled and how long it took the object to travel that distance. B. An object’s velocity is determined by the distance the object traveled, how long it took the object to travel that distance and what acceleration the object traveled. C. An object’s velocity is determined by the distance the object traveled and how long it took the object to travel that distance. D. An object’s speed is determined by the distance the object traveled, how long it took the object to travel that distance and what direction the object traveled.
Answer:
Explanation:
D
An object’s speed is determined by the distance the object traveled, how long it took the object to travel that distance, and what direction the object traveled. This statement is correct regarding the speed and velocity of an object.
What is velocity ?The directional speed of an item in motion, as measured by a specific unit of time and viewed from a certain point of reference, is what is referred to as velocity.
Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.
Constant acceleration and constant velocity are both forms of motion, as you have already read. Because acceleration is the rate at which velocity changes, constant velocity and constant acceleration go hand in hand.
Thus, option D is correct.

what is the name of an interaction that would form between two ions?
Answer:
Intermolecular forces: are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ).
The interaction that would form between the ions (opposite charged) is called the ion-ion interaction.
What is the ion-ion interaction?Ion-ion interactions are attraction forces between ions that are oppositely charged. They are also known as ionic bonds and are the forces that held together ionic compounds.
The oppositely charged ions floating around in a vacuum will be attracted toward each other, and the attraction will become stronger as they move closer. When they finally stay together and take a considerable amount of energy to separate them.
They produce an ion-pair, a new particle that has a positively and negatively charged surface. The clusters tend to develop because these ion pairs and free ions have strong connections and finally fall out of the gas state as a liquid or solid.
The attraction forces of ions with opposite charges are called ion-ion interactions. The ions with similar charges repel each other, whereas ions with opposite charges attract.

Explanation:
A student wants to calculate the heat gained of 100 grams of water in order to
calculate the specific heat of a metal in the following problem. The water is
heated from 25C to 50C when the metal is added. The specific heat of water is
4.18 J/gºC. Use Q=m xCxT*
The quantity of heat gained to raise the temperature from 25.0°C to 50.0°C is 10,450 Joules.
Given the following data:
Mass of water = 100 gramsInitial temperature = 25.0°CFinal temperature of water = 50.0°CSpecific heat capacity of water = 4.18 J/g°CTo find the quantity of heat gained:
Mathematically, heat capacity or quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the heat capacity or quantity of heat.m represents the mass of an object.c represents the specific heat capacity.∅ represents the change in temperature.Substituting the values into the formula, we have:
[tex]Q = 100(4.18)(50 - 25)\\\\Q = 418(25)[/tex]
Quantity of heat = 10,450 Joules.

NEED HELP ASAP! Write a statement explaining your claim about whether or not the equation is correctly balanced.
Then, provide evidence that supports your claim about whether or not the equation is correctly
balanced. Next, connect your evidence to your claim about the equation.
Answer:
I think that it it correctly balanced that is my opinion and, because the way it is set up, that the answer will tell you weather or not it is correctly balanced or not.
Evaluating the number of atoms of each element on the product and reactant side, we can conclude that the student's equation isn't balanced.
Given the chemical reaction :
[tex] Al_{4}C_{3} + 6H_{2}O ---> 3CH_{4} + 4Al(OH)_{3} [/tex]
For a balanced equation, the number of atoms of each element in the product side must be equal to that on the reactant side.
Number of hydrogen :
Reactant side = (6 × 2) = 12
Product side = (6 × 2) + (6 × 2) = 12 + 24 = 24
Product side ≠ reactant side ; Hence, the equation isn't balanced
The balanced equation for the reaction goes thus :
[tex] Al_{4}C_{3} + 12H_{2}O ---> 3CH_{4} + 4Al(OH)_{3} [/tex]
Reactant side :
Al = 4
H = (12 × 2) = 24
O = 12
C = 3
Product side :
H = (6 × 2) + (6 × 2) = 12 + 24 = 24
Al = 4
O = 4 × 3 = 12
C = 3
Therefore, the student's equation isn't balanced, the balanced version of the equation has been given .

Im doing a science project and need examples and non-examples of an Atom. some examples of an atom is neon, hydrogen, argon, etc so I got that part. But what are some non-examples of an atom and why?
Answer:
Anything not on the periodic table is an element non example! ... So, for a substance to be an element, all of its atoms must have the same number of protons. Examples of elements include hydrogen, lithium, nickel, and radium.
Explanation:
Non-examples of an atom refer to entities that are not considered atoms.
Molecules consist of two or more atoms chemically bonded together. They are not considered individual atoms because they contain multiple atoms connected by chemical bonds.
Ions are electrically charged particles formed when atoms gain or lose electrons. They can be positively charged (cations) or negatively charged (anions).
Subatomic particles are the constituents of atoms. They include protons, neutrons, and electrons.
Compounds are substances composed of two or more different elements chemically combined.
