So how did y'all find it

These are the answers I remember, and btw I just looked through my revision guide at topics so i could remember questions, that's why i remember so many Image

- Mendeleev also considered their properties
- Acid dissolved forming H+ ions- 34.2 and 0.62 for last questions
- 50.4 for volume of gas- 941 for mass of oxygen
- Alpha particle experiment- some deflected back which means that there's mass in the centre and plum pudding said electrons are in centre but that's wrong as they contain virtually no mass
- Steam train question - water is produced, when heated steam is produced
- for bond energy around -1224 but can't remember exact value
- exothermic because it is a minus value, more energy used in making bonds than breaking them so energy transferred to surroundings
- half equation 2O2- > O2 + 4e-
- At2, gas ( but its solid)
- calcium hydroxide + hydrochloric acid > calcium chloride + water
- badminton racket, nano was the best - for standard from s.f question i got something like 4.0344 x 10 to the power of -4- why do nanotubes conduct electricity
- 3 covalent bonds, delocalised electrons
- why does NH4 have low boiling point - simple molecular structure, weak intermolecular forces, so requires little energy to overcome
- why are dot and cross diagrams bad- don't show relative sizes
- aluminium gains electrons (multiple choice questions)
- how does sodium react with chlorine - violent reaction, temperature change, a lot fizzingLeave your answers Image
