Dichlorine monoxide, Cl2O is sometimes used as a powerful chlorinating agent in research. It can be produced by passing chlorine
Amiraneli [1.4K]

Answer:

% yield =  82.5%

Explanation:

HgO + 2Cl₂ →  HgCl₂ +  Cl₂O

Our reactants are:

  • HgO and Cl₂

Our products are:

  • HgCl₂ +  Cl₂O

We do not have information about moles of reactants, but we do know the theoretical yield and the grams of product, in this case Cl₂O, we have produced.

Percent yield = (Yield produced / Theoretical yield) . 100

Theoretical yield is the mass of product which is produced by sufficent reactant. We replace data:

% yield = (0.71 g/0.86g) . 100 = 82.5%

While conducting a lab experiment, Ali calculated that 1.20 E6 Joules of heat were needed to melt 18.5 kilograms of an unknown s
nordsb [41]

Answer:

Latent heat of fusion of the substance is 6.49\times 10^{4}J/kg

Explanation:

Latent heat of fusion denotes amount of energy (heat) per unit mass required to melt a solid material at constant temperature and pressure i.e. at it's melting point

Here amount of heat required = 1.20\times 10^{6}J

Mass of unknown substance being melted = 18.5 kg

So, latent heat of fusion of the substance = (required heat energy to melt)/(mass of the unknown substance) = \frac{1.20\times 10^{6}}{18.5}J/kg=6.49\times 10^{4}J/kg

So, latent heat of fusion of the substance is 6.49\times 10^{4}J/kg

Argon (Ar): [Ne]3s23p6 core electrons valence electrons
frosja888 [35]

Answer:

1. The core electrons are 10

2. The valence electrons are 8

Explaination:

Core electrons are electrons located in  the inner shells of and atom.

Valence electrons are electrons located on the outermost shell of an atom

From the question given above, we obtained:

Ar (18) => [Ne] 3s²3p⁶

Recall

Ne (10) => 1s² 2s²2p⁶

Therefore,

Ar (18) => [1s² 2s²2p⁶] 3s²3p⁶

From the above illustration,

Inner shell (core shell) => 1s² 2s²2p⁶

Outermost shell (valence shell) => 3s²3p⁶

1. Determination of the core electrons

Inner shell (core shell) => 1s² 2s²2p⁶

Core electrons = 2 + 2 + 6

Core electrons = 10

2. Determination of the valence electrons

Outermost shell (valence shell) => 3s²3p⁶

Valence electron = 2 + 6

Valence electron = 8
