The answer is 2.78 moles of Si
The correct answer is option D, that is, a storage battery is charged using an electric current.
The transformation of one form of energy into another, generally to transform the energy into more useful kind is known as energy conversion. The energy can neither be created nor be destroyed, it can only be transformed. The different forms of energy comprise light, heat, mechanical, electrical, sound, nuclear, and sound.
In the given question, the charging of a storage battery using electric current is an example of electrical energy being converted into chemical energy.
Answer:
Ratio is 1:1
Explanation:
I do not see any coefficients infront of the reactants and the products, therefore, we can automatically assume that every reactant and product is 1 mole. Don't get confused by the 4 off the O. It just means that 1 mole of sulfate has 1 zinc and 4 oxygens.
It is called rust and it forms when water soaks into the metal forming a chemical reaction.
Answer:
because iron is magnetic and sand is not
