Which is NOT true of ionic bonding?
A:
Occurs between metals and non metals
B:
Involves the losing and gaining of electrons
C:
Positive and negative ions are formed?
D:
Involves the sharing of electrons
Answer:
D is wrong
Explanation:
it doesn't involves any kind of sharing of electrons
The statement that is NOT true of ionic bonding is:
D: Involves the sharing of electrons.What is Ionic bondingIonic bonding does not involve the sharing of electrons between atoms. Instead, it involves the transfer of electrons from one atom to another.
In an ionic bond, one atom, typically a metal, donates electrons to another atom, typically a nonmetal, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions). The opposite charges of the ions then attract each other, creating the ionic bond.
Option A is true, as ionic bonding typically occurs between metals and nonmetals.
Option B is true, as ionic bonding involves the losing of electrons by one atom and the gaining of electrons by another atom.
Option C is true, as positive and negative ions are formed as a result of the electron transfer in ionic bonding.
Therefore, the statement that is NOT true of ionic bonding is option D, which states that it involves the sharing of electrons.

How do most diamonds get their color?
Answer:Most naturally-coloured diamonds are created when trace elements interact with the carbon atoms during the diamond's creation. The presence of chemical elements such as nitrogen, sulphur, and boron can colour diamonds in shades of yellow, green, and blue. ... Trace elements have never been found in pink diamonds.
in other words it depends on the heat of how it is made

Which substance do plants use to capture light energy from the sun? a) Carbon dioxide b) Chlorophyll c) Glucose d) Oxygen
Answer: chlorophyll
Explanation:
The substance that plants use to capture light energy from the sun is referred to as chlorophyll.
The chlorophyll is a colored pigment that is used by the plants for photosynthesis. The function of the chlorophyll is that it absorbs the energy from the sun which is then turned into a chemical energy.

Aluminum fluoride is the name of the following ionic compound. The recognised authority on chemical terminology and nomenclature is IUPAC.
IUPAC is the widely acknowledged authority on chemical terminology and nomenclature, and two IUPAC organisations play key roles in this activity: The Interdivisional Commission on Terminology, Nomenclature, as well as Symbols and Division VIII - Chemical Nomenclature or Structure Representation. Unambiguous, uniform, and reliable nomenclature as well as terminology for particular scientific fields are developed by IUPAC as one of its main activities. These recommendations are typically presented as glossaries of terms for particular chemical disciplines. Aluminum fluoride is the name of the following ionic compound.

Describe the pattern of the Lewis dot structures of the first 18 elements (include periods and groups/families)?
Answer:
The Lewis dot structures of elements in the same group are the same (except that the name of the element is shown in the structure) while for elements in the same period it increases by one from left to right.
Explanation:
Lewis dot structures are the structures which represent the valence electrons of an atom. The dots in the structure represent electrons in the valence shell of the atom.
Elements in the periodic table are arranged into groups and periods. The groups are the vertical columns whereas the periods are the horizontal rows. The first 18 elements of the periodic table are Hydrogen(H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon(Ne), Sodium (Na), Magnesium (Mg), Aluminum (Al), Silicon (Si), Phosphorous (P), Sulfur (S), Chlorine (Cl) and Argon (Ar). They are found within Groups IA to VIIIA, as well as from period 1 to 3 in the periodic table. elements in group IA have one valence electron; elements in group IIA has two, IIIA has three, IVA has four, VA has five, VIIA has six, VIIA has seven, while VIIIA has eight valence electrons.
Elements in the same group have the same number of valence electrons while the valence electrons of elements in the same period increase by one from left to right. Therefore, the Lewis dot structures of elements in the same group are the same (except that the name of the element is shown in the structure) while for elements in the same period it increases by one from left to right.
The Lewis dot structure of the first 18 elements is shown in the attachment below.

On a 310 K day, soda is being carbonated in a factory.
a. A 0.031 m
pressure device receives a measurement of 9900 N from the gases in
the soda bottle. What is the pressure of the gases in the soda bottle?
b. Since soda contains water, 47.1 mm Hg of the pressure in the bottle is from water
vapor. What is the pressure of the Co2 in the bottle?
c. Before the CO2 is added to the soda, it's stored in a 1849 L container at 50 atm
and 310 K.
i. How many moles of CO, can fit in the container?
ii. Unfortunately, an accident (blame Steve), dents the container, reducing its
volume to 1399 L. If the number of moles and temperature are still
constant, what is the new pressure?
iii. The factory repairs the container so it's back to its original conditions.
However, the container is weakened, so if the pressure reaches 75 atm it
will burst. If the number of moles and volume are constant, at what
temperature does this burst happen?

Answer:
4 moles...................
Pb(NO3)2
how do i solve this
You can see the periodic table one by one.
Pb(NO3)2 = PbN2O6
So there are
1Pb
2N
6O
and so you find the molecular mass from the periodic table and add all the numbers
Molacular mass of
Pb = 207
N = 14
O = 16
multiply it with the number of atoms
1Pb = 207 × 1 = 207
2N = 14 × 2 = 28
6O = 16 × 6 = 96
Molecular mass total = 207 + 28 + 96 = 331
So the molecular mass is 331.

What happens to the air as a stove heats it? This question is about thermal expansion and convection, not “it gets hot”.
20 points for answering
Answer:
When there is heat at the bottom of this air or water, the air or water molecules in contact with the heat start to move, and the molecules spread apart. The heated air or water becomes less dense. It rises up until it gets to air or water with the same density as it has, and when it gets there, it pushes the air or water that was there out of the way. At the same time, new air or water fills the space that was vacated when the heated molecules rose up. The air or water that gets pushed out of the way falls down. This sets up a circular motion. Air or water is heated at the bottom, travels to the top, cools, gets denser, falls, is heated again and the whole cycle starts again. Convection does not occur in space because there is no gravity. Ovens work by convection. The heating coils at the bottom of the oven heat the air which climbs to the top, cools slightly, and falls down again.

In a sample of double-stranded DNA, 12% of the nitrogenous bases are guanine (G). What percentage of the nitrogenous bases in the sample are cytosine
Answer:
12%
Explanation:
The percentage of Guanine and Cytosine in DNA are equal to each other, as one molecule of guanine bonds with one molecule of cytosine.
If 12% of the nitrogenous bases are guanine, then another 12% will be Cytosine.Conversely, the percentage of adenine and thymine in DNA are equal to each other.
