Answer: 2) 0.21 mole H2O
3) 0.50 mole K2O
4) 123 g Ca( NO3)2
Explanation: solution attached.
For number 2 to find the number of moles of H2O just divide the given in molecules with the Avogadro's number.
For 3 convert grams of K2O to moles by using 1 mole of K2O is equal to the molar mass of K2O
For number 4 moles to grams. Same process with number 3
Answer:
<h3>The answer is 1.99 g/mL</h3>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 16.93 g
volume = final volume of water - initial volume of water
volume = 19.7 - 11.2 = 8.5 mL
We have
We have the final answer as
<h3>1.99 g/mL</h3>Hope this helps you
Answer:
The reactant that is reduced is
Explanation:
The complete equation is as below:
<em>Recall that oxidation involves the gain of electrons while reduction involves the loss of electrons.</em>
In the above reaction, loses electrons to coenzyme Q and becomes reduced to FAD, hence the oxidizing agent. Coenzyme Q gains electrons and becomes oxidized to
, hence the reducing agent.
<u>In order words, </u><u> is reduced while coenzyme Q is oxidized.</u>
