What is the atomic mass of an electron? What type of element is calcium? What is nobelium's atomic mass? How many atoms are in 125 g of calcium? How many atoms are there in 177 g of calcium? How many atoms are in 143 g of calcium?
What element is oxidized?Redox Reaction:In a redox reaction, the proof that a reaction occurs is when there is a change in the number of electrons in the reactants. It is a combination of a reduction reaction which is the reaction involving the gaining of electrons and an oxidation reaction...
Phosphate (PO4) is usually found as calcium phosphate in rock deposits known as apatite and it is a natural source of phosphorus, an element that is essential to life on earth. There is no substitute for phosphorus in human, animal, or plant nutrition and hence in food production. In addi...
To understand what happens when heavy water (D2O) reacts with phosphorus pentoxide (P4O10), we can break down the process step by step.Step 1: Identify the Reactants - The reactants in this reaction are heavy water, which is ch
Predict the charge of the ion formed by each element. a) O b) K c) Al d) Rb What is the formula of the ion that has 16 protons and 18 electrons? What is the charge on the Fe ions in Fe3(PO4)2? Use your knowledge of the periodic table to predict Which ions will form from...
What is the molar mass of CaF2? What is the molar mass, in grams, of a mole of an element equal to? What is the mass of one mole of H2? What is the molar mass of CaCO3? What is the molar mass of CuCl2? What is the molar mass of calcium hydroxide? What is the molar mass ...
One of these benefits is an increased whitening effect. While HAp doesn’t change the “polishing” activity of toothpaste, it adds a whitening element not otherwise seen by standard toothpaste. HAp literally “fills in” the enamel of your teeth with healthy tooth structure, altering the appeara...
The structural hypothesis which is proposed is related to the formation of amorphous whewellite, a new polymorph recently synthesised. Thus, in such cases, special attention should be paid to the stone morphology (and not FTIR spectrum), which is a major element for clinical diagnosis as already...
