Answer:
onic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
Explanation:
In the give question, ionic bonds are formed between metals and nonmetals.
An ionic bond is a type of chemical bond that involves the transfer of electrons from one atom to another.
Metals tend to lose electrons easily, while nonmetals tend to gain electrons easily. So, ionic bonds are typically formed between metals and nonmetals.
For example: Table salt (NaCl)
It is formed when sodium (Na), a metal, loses an electron to chlorine (Cl), a nonmetal, which gains that electron. The resulting ions,[tex]\rm Na^+\ and \ Cl^-[/tex], are then attracted to each other, forming an ionic bond.
Therefore, metals and nonmetals combine together to form ionic bonds.

Consider the above reaction. If some CO2 were removed from the container, what would the reaction do in an attempt to replace the CO2?
Answer:
See explanation
Explanation:
The reaction to be considered is shown below;
H2CO3<------->CO2 + H2O
We know that when a constraint such as a sudden change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the system has to adjust itself by shifting in a particular direction in order to cancel the constraint.
Now, if we remove CO2, the equilibrium position must shift to the right by the decomposition of more H2CO3 to establish equilibrium again.
what is preferential discharge of ions
Answer:
During the process of electrolysis, ions that are formed will get discharged to reform neutral atoms at the state of electrons, whereas the preferential meaning which in case one or more kind of cations and anions in the electrolyte, the one with the higher concentration or at a lower position activity will get discharged first.

Equations can be balanced by using the half-reaction method. Which step should be completed first when using this method?
Answer:
Separate the reaction into half equations
Explanation:
When we want to balance redox equations, we must take cognizance of the fact that a specie was oxidized and another specie was reduced.
Hence we must identify the specie that was oxidized and the one that was reduced and then break up the whole redox reaction into oxidation and reduction half equations.

Explanation:
Both covalent-network solids and ionic solids can have melting points well in excess of room temperature, and both can be poor conductors of electricity in their pure form. However, in other ways their properties are quite different. a. Which type of solid is more likely to dissolve in water
Answer:
IonicEvidence: It can be proved by a simple experiment, sand doesn't dissolve in water but NaCl (table salt) does. (excluding cases like BaSO4 and sugar and amino acids)Cause: The electrostatic bonds among ions in a lattice only hold them together like two magnets with unlike poles facing each other. The water molecules can split them through the similar process with several molecules ganging up on them, the H+ parts of the molecules attracts the anion and O2- part; the cations. If this electrostatic attraction is big enough, the bonds between the solid's ions break (into separate ions). And so the solid dissolves. This is usually the case with most.
Why not covalent structures?: Sure, covalent solids have a low m.p and b.p for low intermolecular forces, the covalent bonds here are strong and cannot easily be 'pulled apart' by water molecules. They usually have stronger intermolecular forces than that of water.
But... if their intermolecular forces are weaker or similar, sure they can dissolve easily. Like any often-used alcohol (glacial).

why does a freely suspended iron rod does not point at N-S directions always
Answer:
This is because their is a repulsive force between the magnetic north and the geographical north since the rod experiences the Earth's magnetic field.
The iron rod deflects at an angle (angle of dip) from the horizontal.

The volume of a sample gas is 650.ML at 0.00C. What volume will the sample occupy at 75C?
Answer: 828.57mL
Explanation:
First and foremost, we need to convert the degree in Celcius to Kelvin, this will be C + 273 = K
Temperature 1 = 0 + 273 = 273K.
Temperature 2 = 75 + 273 = 348K.
We then plug the values gotten into.the formula which will give:
650/273 = x/348
X = (650 × 348) / 273
X = 828.57mL
The volume that the sample will occupy at 75C would be 828.57mL.
What volume (in liters) does 3.91
moles of nitrogen gas at 5.35 atm

Explain the purpose and function of a gene.
Function
Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.
Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.
Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.
Purpose
The purpose of genes is to store information.
Each gene contains the information required to build specific proteins needed in an organism.

How much water would you need to add to 500 mL of a 2.4 M KCl solution to make a 1.0 M solution?
Answer:
Use dilution equation:
M1V1 = M2V2
1.0*V1 = 2.4*500
V1 = 1200mL
You already have 500mL KCl solution . You must add: 1200mL - 500mL = 700mL water.
