5 0

The equation that is a decomposition reaction is

PbCO3(s) ---> PbO(s) + CO2(g)

That is option D.

<h3>Properties of a decomposition reaction</h3>

A chemical reaction is defined as the combination of substances called reactants to form a product. The various types of chemical reaction include:

  • synthesis reaction

  • combustion reaction

  • decomposition reaction

  • single or double replacement reaction

Decomposition reaction is that type of chemical reaction in which the reactant breaks down to form two or more products.

Therefore the heating of lead (II) carbonate is a decomposition reaction.

You are given 24.3 grams of Mg and combine it with 32.1 grams of Sulfur, what is the mass of MgS? *
koban [17]

Answer:

ExplanatioFirst let us compute for the molar mass of Mg(OH)2.

molar mass = 24.3 + 2 (16) + 2(1.0)

molar mass = 58.3 g/mol

 

So the mass is then:

mass = 3.2 mol * (58.3 g/mol)

mass = 186.56 gramsn:

As we increase the temperature of a liquid, its properties change. Which of the following would NOT be an expected change in the
taurus [48]

Answer: c. increase in surface tension

Explanation:

a) Viscosity : is defined as the resistance to the flow of a fluid. More are the inter molecular forces between the particles of a liquid, the more the viscosity of the liquid and thus it will flow slowly.

Viscosity decreases with increase in temperature as the forces among particles decrease due to increase in kinetic energy and thus they offer less resistance to flow.

c) Surface tension : is the downward force acting on the surface of liquid due to presence of inter molecular forces or cohesive forces between the particles of liquid.

Surface tension decreases with increase in temperature as the forces among particles decrease due to increase in kinetic energy.

d) Vapor pressure: Vapor pressure of a liquid  is defined as the pressure exerted by the vapors  in equilibrium with the solution at a particular temperature.

Vapor pressure increases with increase in temperature as the forces among particles decrease ad more particles can escape as vapors.

e) Evaporation is the the process in which liquid changes into gaseous state below its boiling point.

Evaporation increases with increase in temperature as the forces among particles decrease ad more particles can escape as vapors.
