Chemistry- Acids, Bases, And Buffers Written Exam 2024. Define Acid - correct answer A proton donor. Define Base - correct answer A proton acceptor. Why is H+ a Proton - correct answer Because hydrogen is just one proton and one electron. Take away the electron and you're left with H+. Define Alkali - correct answer A type of base which dissolves in water to form OH- ions (a soluble base). What is a Monobasic Acid and Give an Example of One - correct answer A monobasic acid e.g. ...

Equilibrium (harbor process), alloys, LCAs, water Questions and Answers 2023 Why do we need fertilisers -plants need nitrogen to grow + make proteins When the crop is harvested, most parts don't rot back into the soil -> less nutrients for next plant -nitrogen is insoluble in water and plants need to absorb a soluble form of nitrogen -nitrogen from the air -> nitrogen compounds mean they can be absorbed What is equillibrium? the rate of the forward reaction is equal to the...

An example of white-collar crime includes: Money laundering activities The organisation WHISPER works for the decriminalisation of prostitution and can be categorised as: Radicalist Feminists From a criminological perspective, Siegel (2004) defines a public order crime as a: Crime which involves acts that interfere with the operations of society and the ability of people to function efficiently The theoretical explanation of conservation crime employs a combination of existing theorie...
