Your answer would be 0.00285 moles.
It well be 9025 because it will dissolve in 0.8 hcl soluiton
Answer:
Analytical Groups I and II
Explanation:
Precipitation reactions happen when anions and cations in aqueous solution mix together to form an insoluble ionic solid which is now referred to as a precipitate.
Whether or not a type of reaction like that takes place can be determined by utilizing the solubility principles for common ionic solids.
Answer:
<h2>12 atm</h2>
Explanation:
To find the initial pressure we use the formula for Boyle's law which is
Since we are finding the initial pressure
From the question we have
We have the final answer as
<h3>12 atm</h3>
Hope this helps you
Answer:
Mass of ring = 32 g
Volume of ring = 4 mL
Density of ring = 8 g/mL
Explanation:
From the question given above, the following data were obtained:
Mass of ring = 32 g
Volume of water = 64 mL
Volume of water + ring = 68 mL
Density of ring =?
Next, we shall determine the volume of the ring. This can be obtained as follow:
Volume of water = 64 mL
Volume of water + ring = 68 mL
Volume of ring =?
Volume of ring= (Volume of water + ring) – (Volume of water)
Volume of ring = 68 – 64
Volume of ring = 4 mL
Finally, we shall determine the density of the ring. This can be obtained as follow:
Mass of ring = 32 g
Volume of ring = 4 mL
Density of ring =?
Density = mass / volume
Density of ring = 32 / 4
Density of ring = 8 g/mL
