is CdCi2 covalent or ionic
Answer:
binary and 11
Explanation:
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding. In case of calcium chloride, the calcium gives up an electron to each chlorine atom, becoming Ca2+ ions and chlorine become Cl– ions.

What is the practical application of melting point in the study of matter?
Answer:
Melting points are often used to characterize organic and inorganic crystalline compounds and to ascertain their purity. Pure substances melt at a sharp, highly-defined temperature (very small temperature range of 0.5 – 1 °C) whereas impure, contaminated substances generally exhibit a large melting interval.

While the Bohr model fails to show the true shape of the electron orbitals with in an atom, it is still used because it ?
Answer:
Is used to predict the spectra of hydrogen and hydrogen like species
Explanation:
The Bohr's model of the atom was propounded by Neis Bohr. In his theory, an atom is composed of quantized energy levels in which electrons may be found.
The transition of an electron between energy levels leads to the absorption or emission of energy in the form of a photon of visible light. The energy absorbed or emitted depends on the energy difference between the two energy levels.
The model is successful at predicting the electronic spectra of one electron species but totally fails when the specie has more than one electron. Also, the model fails to show the true shape of the electron orbitals within an atom.
Example #1: 0.450 mole of Fe contains how many atoms?
Answer:
Number of Fe atoms = 2.709 × 10^23 atoms.
Explanation:
Given the following data;
Number of Fe moles = 0.450 mole
We know that Avogadro constant is equal to 6.02 * 10^23 mol¯¹
Number of Fe atoms = number of Fe moles * Avogadro constant
Substituting into the equation, we have;
Number of Fe atoms = 0.450 × 6.02 * 10^23
Number of Fe atoms = 2.71 × 10^23 atoms.
Note: Fe is the symbol for the chemical element Iron.

plzzzzzz help mee
also friction is not the answer
Answer:
Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.

4. Calculate the number of carbon (C) atoms present in the 25 mL of sugar.
Show all your workings
*
Answer: [tex]8.38\times 10^{23}atoms[/tex] of carbon
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
mass of sugar= [tex]density\times volume=1.59g/ml\times 25ml=39.75g[/tex]
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{39.75g}{342.3g/mol}=0.116moles[/tex]
1 mole of sugar [tex]C_{12}H_{22}O_{11})[/tex] contains = [tex]12\times 6.023\times 10^{23}=72.28\times 10^{23}atoms[/tex] of carbon
0.116 mole of sugar [tex]C_{12}H_{22}O_{11})[/tex] contains = [tex]\frac{72.28\times 10^{23}}{1}\times 0.116=8.38\times 10^{23}atoms[/tex] of carbon

What is the relationship between molecular motion and energy?
Answer:
Because the particles are in motion, they will have kinetic energy. The particles will not all have the same energy, and the energy of the particles is constantly changing as they undergo changes in speed. Thus, for a given sample of matter, we can only talk about the average kinetic energy of the particles.
Explanation:
I hope this helps and pls mark me brainliest :)
We do know that if we "give" energy to a given object, the temperature of the object increases.
So there is a direct relationship between temperature and energy.
From this idea, we can conclude that:
"As we increase the energy, we also will see an increase in molecular motion."
We also do know that, as the temperature of an object increases, also does the kinetic energy of the particles that conform to the object (as the kinetic energy increases, the particles move more, this is why as we increase the temperature we usually see an increase in the volume of the object).
This increase in kinetic energy is related to the molecular motion (the movement of the electrons and nucleus o a molecule) as the kinetic energy of these parts increase, these move more.
So the relationship between molecular motion and energy is:
As we increase the energy, we also will see an increase in molecular motion.

What is the volume occupied by 40 grams of argon gas (Ar) at standard conditions?
Answer:volume occupied by 40 grams of argon gas (Ar) at standard conditions = 22.443L
Explanation:
Using the ideal gas law that
PV =nRT
Where p =pressure,
V = volume,
n = number of moles
R = gas constant, and
T= temperature in Kelvin.
Since Argon is at STP( Standard conditions), This means that temperature is 273.15 K and pressure is 1 atm
Also the gas constant= 0.08206 L atm/K mol . we are using this value because its units match the units of our values to aid easy calculation
So,
Number of moles = Mass/ Molar mass
=40g/39.948 g/mol
Number of moles of Argon=1.0013moles.
Now Bringing
pV= nRT
V= nRT/p
=(1.0013mol x 0.08206 L atm/K mol x 273.15 K ) /1atm
Volume =22.443L

mass
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
mol Calcium phosphate :
n = N : No
n = 4.1 x 10²⁵ : 6.02 x 10²³
n = 68.11
mass Calcium phosphate Ca3(PO4)2 :
= mol x MW

Explanation:
C-14 has a half life of 5730 years, an artifact gives 4 counts per minute on a detector, living matter gives a count of 32. What is the estimated age of the artifact?
Answer:
17188 years
Explanation:
Given that;
0.693/t1/2 = 2.303/t log (Ao/A)
Where;
t1/2 = half life of carbon -14
t = time taken
Ao = activity of a living sample
A activity of the artifact
0.693/5730 = 2.303/t log (32/4)
1.21 * 10^-4 = 2.303/t * 0.9031
1.21 * 10^-4 = 2.0798/t
t = 2.0798/1.21 * 10^-4
t = 17188 years
