KengaRu [80]

Given what we know, we can confirm that in a voltaic cell, the anode loses electrons and is oxidized, meanwhile, the cathode is reduced by gaining electrons.

<h3 /><h3>What is a voltaic cell?</h3>
  • It is described as an electrochemical cell.
  • These cells use chemical reactions to produce electrical energy.
  • During this reaction, an anode loses electrons, thus oxidizing.
  • Meanwhile, the cathode gains electrons and is reduced.

Therefore, given the nature of the voltaic cell, we can confirm that during its reaction, the anode is oxidized by losing electrons while the cathode becomes reduced by gaining them.

During an experiment, 321.1 grams of strontium phosphite are measured into a beaker. How many moles of strontium phosphite are i
Allushta [10]

321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.

<u>Explanation:</u>

It is known that 1 mole of any substance is equal to the molar mass of that substance. So for the case of strontium phosphite, the molar mass is found to be 420.8 g/mol.

This means 1 mole of Strontium phosphite will contain 420.8 g of strontium phosphite.

Then 1 g of strontium phosphite will have \frac{1}{420.8} moles of strontium phosphite.

So, 321.1 g of strontium phosphite will contain \frac{321.1}{420.8}=0.76 moles

Thus, 321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
