What are the names of the elements with the following symbols? (a) Ne (b) Li (c) He Elements of the Periodic Table: Most of the elements of the periodic table were named arbitrarily (e.g. Indium is named after the Latin word indicium for violet). As such, we of...
What would happen if NaOH was added to CuSO4?Question:What would happen if NaOH was added to CuSO4? Displacement reactions:In displacement reactions, more reactive elements displace less reactive elements from compounds as their binding is favourable. The reactivity trends are found in the reactivity...
The formula for copper(II) sulfate is CuSO4. When five water molecules are physically attached to copper(II) sulfate, it is a blue crystal. Anhydrous (no attached water molecules) copper(II) sulfate is a white crystal. Answer and Explanation: ...
To find the weight of CuSO4.5H2O needed to prepare a 0.5 litre solution of 0.01M Cu(II) ions, we can follow these steps: Step 1: Calculate the number of moles of Cu(II) ions required.The formula to calculate the number of moles is:\(\text{Moles} = \text{Molarity} \times \text...
What is the molar mass of Barium? Atomic Mass and Molar Mass The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of ...
Copper sulfate, also known as cupric sulfate or blue vitriol, is a chemical compound with the formula CuSO4. It is a salt that is highly soluble in water and has a blue color due to the presence of copper ions. Copper sulfate is commonly used as a fungicide, herbicide, and pesticide in...

In a battery or other source of direct current the anode is the negative terminal, butin a passive load it is the positive terminal. For example, in an electron tube electrons from the cathode travel across the tube toward the anode, and in an electroplating cell negative ions are deposited...
