A. CaCl2 and H2O
HCl +Ca(OH)2. CaCl2 +H2O
The ratio of the diffusion rate of Cl2 and O2 is 1.5
calculation
rate of diffusion Cl2/ rate of diffusion O2 =√ molar mass of Cl2/ molar mass of O2
molar mass of Cl2 = 35.5 x2 = 71 g/mol
molar mass O2 = 16 x2 =32g/mol
that is rate of diffusion Cl2/ rate of diffusion of O2 =√ 71/ 32= 1.5
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
Answer: Law of Conservation of Mass.
Explanation:
Law of Conservation of Mass states that during a chemical reaction mass neither created nor be destroyed or total mass of the reactants is equal to the total mass of the products in balanced chemical equation.
Total mass on the reactant side :
(Mass of one methane molecule + mass of two oxygen molecules)
=
Total mass on the product side :
(Mass of one carbon-dioxide molecule + mass of two molecules of water):
=
Total mass on the reactant side = Total mass on the product side = 80 u
The catalytic converter of a secondary air injection system converts the hydrocarbons and carbon monoxide to carbon dioxide (CO2) and water (H2O). It is a fundamental part of a vehicle.
<h3>Catalytic converter and air injection systems</h3>
A catalytic converter refers to the device observed in a car and/or vehicle, which is used to remove different contaminant gases.
In general, the catalytic converter is placed close to the car engine and reduces the release of hydrocarbons.
In general, the air injection system is connected to the catalytic converter in order to provide useful oxygen required for oxidation reactions.
