The total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.

HOW TO CALCULATE NUMBER OF ATOMS:

  • The number of atoms in a substance can be calculated by multiplying the number of moles in that substance by Avogadro's number as follows:

  • no. of atoms = no. of moles × 6.02 × 10²³ mol-¹

  • The number of moles in 7.10g of Cl is calculated as follows:

no. of moles = mass ÷ molar mass

no. of moles = 7.10g ÷ 35.5g/mol

no. of moles = 0.2mol

no of atoms = 0.2mol × 6.02 × 10²³

no. of atoms = 1.204 × 10²³atoms.

  • Therefore, the total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.

When do some atoms in covalent bonds become slightly negative or slightly positive
s2008m [1.1K]

Answer:

A covalent bond is the force of attraction that holds together two atoms that share a pair of electrons. It forms between atoms of the same or different nonmetals. In polar covalent bonds, one atom attracts the shared electrons more strongly and becomes slightly negative. The other atom becomes slightly positive

Why in oxidation of alkylbenzene no matter if alkyl group is big how it removed?​
Nezavi [6.7K]

Answer:

, no matter what the length of the alkyl group in the arene substrate, the product is always a one-carbon carboxyl group. Thus, the benzylic carbon atom has been oxidized and the term benzylic oxidation is appropriate. The term side-chain oxidation is also commonly used.

In alkylbenzenes, the carbon atom which is attached to the aromatic ring is particularly reactive. Reactions taking place at this carbon atom are said to occur at the benzylic position.

Benzylic halides undergo the typical reactions of alkyl halides; thus, you can expect to see such compounds used frequently in multistep syntheses.

The density of honey is 1.42 g/mL. If you poured honey into a glass of water, would it sink to the bottom or float on top? Expla
m_a_m_a [10]

Answer:

The honey would sink to the bottom

Explanation:

A simple interpretation of Archimedes' principle is that, in water, the bodys with density lower than that of water will float on top of the water (That is, density <1g/mL). In the other way, a body with density higher than that of water will sink to the bottom.

As density of honey is higher than density of water:

<h3>The honey would sink to the bottom</h3>

or a particular reaction, Δ H ∘ = − 16.1 kJ and Δ S ∘ = − 21.8 J/K. Assuming these values change very little with temperature, a
Inessa [10]

Answer:

Reaction is non-spontaneous when T > 738.5K and spontaneous when T < 738.5K

Explanation:

A reaction is non-spontaneous when ΔG° > 0 and is spontaneous when ΔG° < 0

ΔG° is defined as:

ΔG° = ΔH° - TΔS°

ΔG° will be > 0 (non-spontaneous) when  ΔH° > TΔS° and vice versa. Thus:

-16100J > T × -21.8J/K

738.5K > T

That means the reaction is <em>non-spontaneous when T > 738.5K and spontaneous when T < 738.5K</em>

I hope it helps!
