Answer:

Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

Based on the molecular structures of chloromethane and methane shown, a student makes the claim that a pure sample of chlorometh

goblinko [34]

Answer:

Yes, chloromethane has stronger intermolecular forces than a pure sample of methane has.

Explanation:

In both methane and chloromethane, there are weak dispersion forces. However, in methane, the dispersion forces are the only intermolecular forces present. Also, the lower molar mass of methane means that it has a lower degree of dispersion forces.

For chloromethane, there is in addition to dispersion forces, dipole-dipole interaction arising from the polar C-Cl bond in the molecule. Also the molar mass of chloromethane is greater than that of methane implying a greater magnitude of dispersion forces in operation.

Therefore, chloromethane has stronger intermolecular forces than a pure sample of methane has.

Explain why diamonds are useful for electrodes in batteries

umka21 [38]

Answer:

Diamonds have a broader potential window of 3 to 5 volts.

Explanation:

The minimum voltage required for electrolysis is called potential window. Electrodes such as titanium electrodes and those made of noble metals have a potential window of about 2 volts. Diamond has a potential window of 3 to 5 volts that makes it preferentially start a redox reaction of a substance that is difficult to electrolyze. This facilitates electrolysis of substance that were difficult to decompose in normal electrochemical systems.

1.40 m3 is how many mL

Zarrin [17]

$\LARGE{ \boxed{ \rm{ \pink{Solution:}}}}$

We know, 1 m³ of space can hold 1000 l of the substance.

⇛ 1 m³ = 1000 l----(1)

And, 1 l is 1000 times more than 1 ml

⇛ 1 l = 1000 ml------(2)

So, From (1) and (2),

⇛ 1 m³ = 1000 × 1000 ml

⇛ 1m³ = 1000000 ml

We had to find,

⇛ 1.40 m³ = 1.40 × 1000000 ml

⇛ 1.40 m³ = 140/100 × 1000000 ml

⇛ 1.40 m³ = 1400000 ml

⇛ 1.40 m³ = 14,00,000 ml / 14 × 10⁵ ml / 1.4 × 10⁶ ml

☃️ So, 1.40 m³ = 14 × 10⁵ ml / 1.4 × 10⁶ ml.

Compare the mass number and atomic number for isotopes of an element. Explain your answer

Papessa [141]

Answer:

The atomic number is the number of protons in the nucleus and also the number of orbiting electrons. The mass number is the number of protons and neutrons in the nucleus.

The mass number minus the atomic number is the number of neutrons in the nucleus.

An isotope will have a different atomic mass.
