1Match the colours to the element
- Ared
- Bblue-green
- Corange-red
- Dlilac
- Eyellow
- Forange
- Gbrown
- Hgreen
- Iblue
- Jpink
2Dilute sodium hydroxide solution (NaOH) is used to test for some metal ions and can also be used to identify ammonium ions. Write the colour of the precipitate formed next to each ion.
aluminium [blank_start]white[blank_end]
calcium [blank_start]white[blank_end]
copper [blank_start]blue[blank_end]
iron(II) [blank_start]green[blank_end]
iron(III) [blank_start]brown[blank_end]- Awhite
- Bwhite
- Cblue
- Dgreen
- Ebrown
3Holding a piece of damp, red litmus paper over ammonia gas will turn the litmus paper blue.
- ATrue
- BFalse
4Match the chemical test to to the ions
- Aadd acid, then barium chloride
- Badd nitric acid, then silver nitrate
- Cadd silver nitrate
- Dadd barium chloride
- Eadd dilute acid
5New technology, developed over the last few decades, have considerably advanced analytical chemistry. These new instrumental methods have three main advantages, they are:
- Afaster
- Bmore accurate
- Cmore sensitive
- Dcheaper
- Eless noisy
- Fbetter for the environment
6The calibration curve shows that a flame photometer reading of 5 units, would mean a sample has a concentration of 0.025 g/dm3.
What would a reading of 9 units mean? [blank_start]0.045[blank_end] g/dm3
- A0.045
7Alkenes have the general formula of CnH2n+2
- ATrue
- BFalse
8Because alkenes contain at least one double bond between carbon atoms, we describe them as [blank_start]unsaturated[blank_end] compounds.
- Aunsaturated
9The test for [blank_start]alkenes[blank_end] makes use of the [blank_start]addition[blank_end] reaction, and involves adding bromine water to a sample of hydrocarbon. If an [blank_start]alkane[blank_end] is present the solution stays [blank_start]orange-brown[blank_end], but an [blank_start]alkene[blank_end] will turn the solution colourless. This is because the bromine is added across the carbon-carbon [blank_start]double[blank_end] bond.
- Aalkenes
- Balkanes
- Caddition
- Dcondensation
- Ealkane
- Forange-brown
- Gcolourless
- Halkene
- Idouble
- Jsingle
10Name the polymer formed from the monomer propene.
[blank_start]poly(propene)[blank_end]- Apoly(propene)
11Which of the following is not a reason we would want to use a polymer such as poly(propene) to make plastics for rope?
- Aflexible
- Bstrong
- Cshatter-resistant
- Dslippery
12DNA is a [blank_start]polymer[blank_end] made from four different monomers called [blank_start]nucleotides[blank_end]. Most DNA molecules are made from two polymer chains. These polymer chains join together in the shape of a [blank_start]double helix[blank_end]. Each nucleotide is made of a sugar molecule, a base (A, C, T or [blank_start]G[blank_end]), and a phosphate group.
- Anucleotides
- Bdouble helix
- CG
- Dpolymer
13Most ethanol is made from plants, making it a renewable resource. The process is called fermentation, and requires: (check all that apply)
- Awater
- Byeast enzymes
- Can absence of oxygen
- Dtemperatures between 25 - 35 °C
- Eethanol
- Fcarbon dioxide
14Fermentation will produce a dilute solution of ethanol, and needs to be purified to remove water and other liquids, as well as insoluble substances, to produce pure ethanol.
- ATrue
- BFalse
15Carboxylic acids have the functional group of [blank_start]-COOH[blank_end] ([blank_start]carboxyl[blank_end]), and gives rise to the ending of carbox[blank_start]ylic acid[blank_end]. It is responsible for the general reactions that [blank_start]all[blank_end] carboxylic acids can do.
- A-COOH
- B-OH
- Ccarboxyl
- Dhydroxyl
- Eylic acid
- Fol
- Gall
- Hsome
16Which of the following is a reaction that alcohols can do?
- Areact with metals to form a salt and hydrogen
- Breact with bases to form a salt and water
- Creact with carbonates to form a salt, water and carbon dioxide
- Dwill react with the alkali metals to produce hydrogen and a metal hydroxide
17People are concerned the small size of [blank_start]nanoparticles[blank_end] makes it possible to breathe them in, or to pass into [blank_start]cells[blank_end] - once inside the [blank_start]body[blank_end], they might catalyse reactions that are harmful producing [blank_start]toxic[blank_end] substances. Modern [blank_start]nanoparticulate[blank_end] materials have not been used for long, so it is [blank_start]difficult[blank_end] for scientists to determine their risks.
- Ananoparticles
- Bcomposites
- Ccells
- Dour lungs
- Ebody
- Fbrain
- Gtoxic
- Hsafe
- Inanoparticulate
- Jdifficult
- Keasy
18Most composite materials have two components:
the [blank_start]reinforcement[blank_end], the substance that makes up the bulk of a composite material
the [blank_start]matrix[blank_end], which binds the reinforcement together- Areinforcement
- Bmatrix
19Nanoparticles are about 1-100 nanometres (nm) in size, that contain only a few hundred atoms.
- ATrue
- BFalse
