Catalytic converters are fitted in the exhaust systems of many cars.
Which gas:
● causes acid rain if it is released into the air
● is removed from car exhaust fumes by a catalytic converter?
carbon dioxide
carbon monoxide
hydrocarbon vapour
nitrogen dioxide
Which statement is correct?
Ammonia reacts with alkalis to form the ammonium ion.
Ammonium chloride contains ionic, covalent and co-ordinate bonds
The ammonium ion reacts with acids to produce ammonia.
The bond angle in the ammonium ion is approximately 107°.
At 550 °C nitrogen dioxide reacts with unburnt hydrocarbon fragments such as CH3 in the catalytic converter of a motor vehicle.
4CH3 + 7NO2 → 3.5N2 + 4CO2 + 6H2O
Which row gives the energy change for this reaction and a possible reason for it?
A
B
C
D
Ammonium sulfate, (NH4)2SO4, and ammonium nitrate, NH4NO3, are used as fertilisers.
These salts have different percentages by mass of nitrogen. They have the same effect as each other on the pH of wet neutral soil.
Which row is correct?
A
B
C
D
Which processes involve the conversion of sulphur dioxide into sulphur trioxide?
the combustion of sulphur contaminated carbonaceous fuels
the Contact process for manufacturing sulphuric acid
the catalytic oxidation of sulphur dioxide by oxides of nitrogen
Ammonia and chlorine react as shown.
8NH3 + 3Cl2 → N2 + 6NH4Cl
Which statements are correct?
Each nitrogen atom is oxidised
Each chlorine atom is reduced.
Ammonia behaves as a base.
Which gas is present in the exhaust fumes of a car engine in a much greater amount than any other gas?
carbon dioxide
carbon monoxide
nitrogen
water vapour
Sulfur dioxide and sulfites are used in food preservation.
Why are they used for this purpose?
They are reducing agents which slow down the oxidation of food.
They inhibit the growth of aerobic bacteria.
They react with NO2(g) converting it to NO(g).
In a car engine, non-metallic element X forms a pollutant oxide Y.
Further oxidation of Y to Z occurs in the atmosphere. In this further oxidation, 1 mol of Y reacts with ½ mol of gaseous oxygen.
What can X be?
carbon
nitrogen
sulfur
Ammonia exists as simple covalent molecules, NH3. Ammonia can react with suitable reagents to form products containing ammonium ions, NH4+. Ammonia can also react with suitable reagents to form products containing amide ions, NH2–.
Which of these nitrogen-containing species are present in an aqueous solution of ammonia?
ammonia molecules, ammonium ions and amide ions
ammonia molecules and ammonium ions only
ammonia molecules only
ammonium ions only
Which statement does not describe an effect of acid rain on the environment?
Acid rain causes erosion of stone buildings.
Acid rain causes ozone depletion.
Acid rain increases the corrosion of some metals.
Acid rain increases the leaching away of essential nutrients and minerals from soils.
Which statements explain why nitrogen gas is unreactive?
Nitrogen atoms are highly electronegative.
Nitrogen molecules are non-polar.
The triple bond between nitrogen atoms is very strong.
______________ ______________ is produced when fuels containing sulfur are burned in the presence of oxygen.
