16

Explanation:

The subatomic particles in any atom are made up of protons, neutrons and electrons in it.

Protons are the positively charged particles.

Neutrons do not carry any charges.

Together with protons, they occupy the nucleus.

Electrons are negatively charged particles.

  In an atom of B - 11;

  11 is the mass number

mass number = number of protons + number of neutrons.

   Total subatomic particles = proton + neutrons + electrons

    TSP = mass number + electrons

In B, the atomic number = 5 = number of electrons

   TSP = 11 + 5 = 16

At 1173 K, Keq = 0.0108 for the following reaction: CaCO3(s) ⇄ CaO(s) + CO2(g) The reaction takes place in a 10.0 L vessel at 11
maxonik [38]

Answer:

The amount of calcium carbonate will increase.

Explanation:

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • K>Q , reaction will move forward by making more product.
  • K<Q , reaction will move backward by making more reactant.

CaCO_3(s)\rightleftharpoons CaO(s) + CO_2(g)

Equilibrium constant of the reaction = K_{eq}=0.0108

Concentration of CaO=\frac{15.0 g}{56 g/mol\times 10.0L}=0.027 M

Concentration of CO_2=\frac{4.25 g}{44 g/mol\times 10.0L}=0.0096 M

Concentration of CaCO_3=\frac{15.0 g}{100 g/mol\times 10.0L}=0.015 M

Q=\frac{[CaO][CO_2]}{[CaCO_3]}

=\frac{0.027 mol/L\times 0.0096 mol/L}{0.015 mol/L}=0.0174

K_{eq}

This means that equilibrium will move in backward direction by which amount of calcium carbonate will increase.

How many moles are in 428 L of chlorine gas
djyliett [7]

Answer:

19.3 moles

Explanation:

In order to calculate the number of moles of Chlorine gas from the volume, we have to calculate its mass from its known density using the formula:

Density (g/L) = mass (g) /volume (L)

Density of Chlorine gas= 3.2g/L

Volume = 428L

3.2 = mass/428

mass = 428 × 3.2

mass = 1369.6g

Using mole = mass ÷ molar mass

Molar mass of chlorine (Cl2) = 35.5 × 2

= 71g/mol

mole = 1369.6 ÷ 71

mole = 19.2901

mole = 19.3 moles
