Hello there,
You should know the <span>solubility of AgNO3 in water at 20°C equals to 2220 g/L.
So we can say that in 1 L of water, 2220 g of AgNO3 can be dissolve.
Now you should know 1L = 1000g.
Which means 1000 g of water can dissolve 2220 g of AgNO3.
Therefore :
</span>250 g<span> --> x
1000 g --> 2220 g
So : </span>
.
In short, 555g of AgNO3 can be dissolved in 250g of water at 20°C.
Hope this helps !

Answer: The correct answer is X represents water and Z represents oxygen.
Explanation:
Cellular respiration is defined as the breaking of sugar into a form that a cell can use as energy. This breaking of glucose takes place in the presence of oxygen gas.
Equation for the cellular respiration is given by the chemical reaction:
Here, = Glucose
For the given chemical equation in the question,
Z represents oxygen gas
X represents either carbon dioxide or water
Y represents either carbon dioxide or water
Hence, the correct answer is X represents water and Z represents oxygen.
