Science and Chemistry GCSEs are designed as two-year courses, assessed by written examinations at the end of the course. Scottish National courses have similar content. As part of the National Curriculum, the Department for Education publishes Science programmes of study showing the content that must be covered.
The examination boards base their specifications on this content, with some differences in approach and with varying additional content. All Rights Reserved.Skip to main content GCSE.

Organic Chemistry Paper 3.The concentration of a solution can be measured in g dm -3 or in mol dm It is more useful to know the concentration of a reactant in mol dm -3 as the amount of reactant in a given volume can be calculated. The concentration of a solution can be calculated using:. The units for concentration can also be shown as mol dm 3 or M for 'molar'but these mean the same as mol dm 3. Calculate the concentration of the sodium hydroxide solution formed. Volumes used in concentration calculations must be in dm 3not in cm 3.
This means:. For example, cm 3 is 0. It is often easiest to convert from cm 3 to dm 3 before continuing with a concentration calculation. Calculate the concentration of the acid in mol dm The relative formula massM rof the solute is used to convert between mol dm -3 and g dm -3 :.
Calculate the concentration of 0. Calculating concentrations The concentration of a solution can be measured in g dm -3 or in mol dm Concentration using moles The concentration of a solution can be calculated using: the amount of dissolved solute in moles mol the volume of solution or solvent in cubic decimetres dm 3 curriculum-key-fact.The symbol key for beryllium as represented on the Periodic Table.

Since atoms are neutralthen it is also the same as the number of electrons. The mass number is the number of protons plus neutrons. The number of neutrons can thus be calculated by subtracting the atomic number from the mass number. Beryllium for example has an atomic mass of 4, therefore it has 4 protons and 4 electrons.
Relative Atomic mass The symbol for the relative atomic mass is A r and it is sometimes written as R. It is calculated from the mass number and relative abundances of all the isotopes of a particular element. Since isotopes have the same atomic number but a different mass number, they are all atoms of the same element but have different atomic masses. The relative atomic mass is an average of these masses, hence it is not always a whole number.
The following equation is used to calculate the relative atomic mass from the given isotopes present:. The top line of the equation can be extended to include the number of different isotopes of a particular element present. Need help? Covalent Bonding Fundamentals of Covalent Bonding 5.

BBB customer reviews allow customers to post positive, negative or neutral reviews about marketplace experiences with businesses, brands and charities. Just like our complaints, reviews are vetted by BBB team members and sent to the business before they are published online.
Consumers, upon request of BBB and businesses, must be able to provide substantiation of the marketplace interactions. For more than 100 years, BBB has been a trusted resource in our marketplace.GCSE Science Revision Chemistry \
The additional information and current feedback in customer reviews is something consumers have told us is important to them when they chose to work with trustworthy businesses. Businesses like the idea too. Ultimately, BBB customer reviews help both consumers and businesses make wise purchasing decisions.
Customer Reviews are the subjective opinion of the individual who posted the review and not of Better Business Bureau. BBB cannot guarantee the accuracy of any customer review and is not responsible for the content of any customer review. Why BBB Customer Reviews are Different: True to form - BBB processes customer reviews in an ethical, fair, unbiased manner and we do it consistently Reviews each and every customer review before posting them Provides an opportunity to challenge the identity of the reviewer before the review is posted- not allowing anyone to post fake or ill-intended reviews BBB does not post any anonymous reviews Sends the submission to the business - allowing the business to provide additional feedback to help address the reviewers issues Protects the identity of the submissions by not posting personally identifiable information Validates the email address of all reviewers In some instances works with both consumer and business to help work through the issues Uses the data to help investigate businesses The Difference Between a Complaint and a BBB Customer Review:.
