Explanation:
A. Hydrogen bonding is present in CS2 but not in CO2.
B. CS2 has greater dipole moment than CO2 and thus the dipole-dipole forces in CS2 are stronger.
C. CS2 partly dissociates to form ions and CO2 does not. Therefore, ion-dipole interactions are present in CS2 but not in CO2.
D. The dispersion forces are greater in CS2 than in CO2.

Are cations nonmetals
and anions are metals?
Answer:
First, each element that forms cations is a metal, except for one (hydrogen), while each element that forms anions is a nonmetal. This is actually one of the chemical properties of metals and nonmetals: metals tend to form cations, while nonmetals tend to form anions. Are positive ions metals or nonmetals?

what do an atom ion and isotope of an element have in common?
An atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.
WHAT IS AN ION AND ISOTOPE?An ion is a charged atom while an isotope is the atoms of an element with the same atomic number but different atomic mass.
For example; Mg2+ is the ionic form of Magnesium while C-12 and C-14 are isotopes of carbon.
Here the ion of an atom will have a different charge but the same mass.
Also The isotope of an atom will have a different mass.
The number of protons V/S the more general atom, an ion has a different number of electrons, and an isotope, a different number of neutrons.
Hence atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.

what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?
Answer:
9.13 x 10^-8 m
Explanation:
The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
What is wavelength?
Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.
Wavelength is calculated as wave speed and frequency.
Wavelength = speed/frequency
SI unit of wavelength is meter.
A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.
Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCI?
A. 3.5 mol/L
B. 150 mol/L
C. 3.3 mol/L
D. 3.5 x 10-3 mol/L
Explanation:
To determine the molarity, we have to find the number of moles in the volume given, and then extrapolate to find the number of moles that would be in 1 L.
Determine the moles in the given volume
moles of LiCl = mass ÷ molar mass
= 139.9 g ÷ 42.39 g/mol
= 3.30 mol
Find the moles in 1 L
Since 930 mL of LiCl = 3.30 mol
then 1000 mL of LiCl = (3.30 mol × 1000 mL/L) ÷ 930 mL
= 3.55 mol/L
How would you change liquid water into ice? Be sure to explain what is happening to the energy (the heat)
Answer:
By putting the liquid water in the fridge
Explanation:
When it is solid the heat will melt to liquid water and if you put it inside a boiling kettle if it boil finished it will bring out gas,if you open it the cover of the kettle you see water if you put it in the fridge and it will be solid again.

what is change in science??
Answer:
A transition from one accepted theory to another or from one employed method to another.
Explanation:
What do these two changes have in common?
boiling an egg
bleaching hair
Select all that apply.
Answer:
destruction of protein bonds
Explanation:
bleach dyes the hair by opening the hair cuticle and dissolving the color (melanin). The longer you leave it on, the more the protein bonds (keratin) are destroyed.
The heat denatures the protein in the egg by disrupting some of its weak bonds that held the molecule into shape

Give the correct order of apparatus (Crucible, Filter funnel, Test tube, Dropper, Spatula) to show the correct arrangement that can be used to prepare and investigate the nature of pH of a sample of onion solution.
Answer:
Is it Crucible,Test tube,Dropper,Filter funnel, Spatula
Explanation:
The laboratory apparatus is used to experiment with the chemicals and to hold them. To prepare and investigate the pH of the onion sample apparatus required are the crucible, test tube, dropper, filter funnel, and spatula.
What is pH?pH is the measurement of the hydrogen or the hydroxide ion concentration in the solution to determine the alkaline or acidic nature of the substance.
The pH of the onion solution can be determined by experimenting with the help of the laboratory apparatus and reagents. A crucible is a container that can withstand high temperatures.
A test tube is a glassware used to hold the substance or chemical in it. Similarly, a dropper is used to draw liquids. The filter funnel separates the filtrate or the solution. A spatula can be used to remove or add the substance.
Therefore, the correct order of the apparatus is the crucible, test tube, dropper, filter funnel, and spatula.
