Chemistry Homework Assistance
QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.
You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.
- If a dilute solution of hydrochloric acid is electrolysed, what gas will be produced at the anod Answer in words not symbols.
- The diagram shows an early attempt at grouping the elements. Do the elements in the seventh column all have similar properties? yes no
- Question 7 of 40 Look at the picture of the periodic table and then fill in the gap in this sentence: The central block of elements is known as the __ metals. Enter your answer
- True or false? The first three elements in group 1 of the periodic table are less dense than water. TRUE FALSE Group 1
- Method 2 - Displacement (d) The chemical equation for the displacement of copper using iron is: CuSO_(4)+Fearrow Cu+FeSO_(4) Calculate the minimum mass of iron needed to displace all of the copper from 50cm^3 of copper(II) sulfate solution. The concentration of the copper(II) sulfate solution is 80 g CuSO_(4) per dm^3 Relative atomic masses (A_(r)):O=16;S=32;Fe=56;Cu=63.5 Give your answer to 2 significant figures. Mass of iron=1.4g_(9)
