The pink brown solid formed from the reaction of zinc with copper sulfate is copper metal. During the reaction, zinc replaces copper in the copper sulfate solution, leading to the formation of solid copper.
Some good GCSE Child Development revision websites include BBC Bitesize, Revision World, and Tutor2u. These websites offer resources such as revision guides, quizzes, and past exam papers to help you prepare for your exams.
The simple answer is that the solid particles of the sugar crystals touch and bump into the water molecules and the water molecules melt the crystals easy as and im only 11! and im already at y11 GCSE level in Chemistry!
The number of orbitals is easy. Find out the number of electrons (atomic number) and then separate it into the relevant shells. GCSE: you are required only to know the electron configuration e.g. 2.8.8.... A-Level: sort it into sub-levels 1s, 2s, 2p, 3s, 3p, 4s, 3d.... Ok, so if you are taking the element Mg into consideration GCSE: 2.8.2 A-Level: 3 row down (so 3rd sub-shell) and the s-block of the periodic table 1s2, 2s2, 2p6, 3s2 Finito!
It depends what it is in Forensics that you want to do.(This information is for English Forensic companies.To become a Forensic Examiner (aka. Assistant Forensic Scientist [£12,900 - £17,000]), most companies require you to have at least:* 4 GCSE's including Maths and a Science (preferably Biology or Chemistry...depending on which area of Forensics you want to go into.) * At least 1 A-Level in a Scientific subject (again, preferably Biology or Chemistry.) * Laboratory experience is desirable but not always necessary.To become a full Forensic Scientist (£19,000 - £30,000 [Potential promotion to Lead Scientist approx £50,000])most companies require at least:* All of the above. * A good honours degree (at least 2:2) in a Scientific (including Forensic Science) or Mathmatic subject. * Laboratory experience is highly desirable (it will be very difficult to get a secure job with no experience).Personal qualities that are desirable include:* Have excellent scientific abilities. * Be a good communicator, both verbally and in writing * Be able to explain complex scientific information in an understandable way.* Be skilled in using statistics to interpret evidence * Be logical, methodical and attentive to detail * Be practical * Be able to produce detailed, accurate reports * Be able to work independently and as part of a team.* Have an enquiring mind * Be self-confident* Be committed to updating knowledge and learning new techniques.Hope that helps.
It completely depends on the difficulty level of the paper, to secure a c, I would say you want about 40% or 50% of the paper but it varies.
