We know that density is a measure of mass per unit of volume:
Density = Mass / Volume
Therefore, we can calculate for the mass
Mass = Density * Volume
if the density of water is 1 g/cm^3:
Mass = Density * Volume
= (1 g/cm^3) * 94.60 cm^3
= 94.60 g
The reaction equation is:
2HF(aq) + Ba(OH)₂(aq) → BaF₂(s) + H₂O (aq)
Writing the ionic form of this equation:
2H⁺ + 2F⁻ + Ba⁺² + 2OH⁻ → BaF₂ + H⁺ + OH⁻
The solubility of barium fluoride is 0.16 grams per 100 ml of water, which means that it is an insoluble compound. Moreover, spectator ions are those that remain unchanged before and after a reaction, so they "spectate" the reaction. In this case, the ions unchanged before and after the reaction are H⁺ and OH⁻.
Rate of the reaction is represented as
Rate=k[A][B]
Rate represents change in product concentration with time that has a unit Ms- Whereas concentration of each reactant can be represented as M . so the expression will become:
Ms-1=k[M][M]
k=M-1 s-1.
Hey there!
Here is your answer:
<u><em>The proper answer to this question is "pressure, deposition, and compaction".</em></u>
Reason:
<u><em>Sedimentary are formed by pressure, deposition, compaction. Which should be in one of your answer choices.</em></u>
Also....
<u><em>This would help you strike out options you don't need, igneous rocks are formed by cooling of magma or lava, and metamorphic rocks are formed by heat and pressure under the Earths surface.</em></u>
If you need anymore help feel free to ask me!
Hope this helps!
