<h2>Answer:</h2>

Yes, As the gravity/distance increases between two objects, the gravitational pull between them weakens/strengthens.

<h2>Explanation:</h2>

There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.

The electron configuration of an element is 1s22s22p¹. How many valence electrons does the element have

Cloud [144]

Answer:

$\huge\boxed{\sf 3 \ electrons}$

Explanation:

<h3>Electronic configuration:</h3>

$1s^22s^22p^1$

The outermost/valence shell is the second one, seeing from the electronic configuration.

<h3>Valence electrons:</h3>

= 2 + 1 = 3 (electrons are raised to the power in the electronic configuration)

Since, the valence shell here is 2, the electrons of second shell will be counted as valence 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.

Identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word ‘chemi

svetoff [14.1K]

Answer 1) $Cl_{2}$ + $H_{2}$ ----> 2 HCl
This is a pure chemical reaction that is taking place.

In this reaction the two chemical species which are Chlorine and Hydrogen undergo addition reaction and form two moles of hydrochloric acid. No new species is formed except the combination of reactants which gives the product.

Answer 2) H + H ----> He + n
This is a nuclear reaction.

As the reactant species is undergoing a reaction which is resulting in formation of new species completely different than the elements in reactants.

Also there is a neutron which is generated after the reaction this is clear indication of nuclear fusion reaction. Hence, it can be called as nuclear reaction.

What is the purpose of adding base in the aldol condensation reaction? choose the best answer.

Paladinen [302]

Base is used in aldol condensation reaction

because it is an organic reaction to form enolate ion, the OH bond present in base help to remove Acidic hydrogen of enolate ion.
