Answer:
Explanation:
When copper metal is dipped into an aqueous solution of 
, copper nitrate (
) is formed. This is type of displacement reaction because copper metal displaces silver from its salt. As only one ion is being displaced, therefore, it is a single displacement reaction.
Copper displaces silver as it is more reactive than silver. This can be confirmed by position of copper and silver in reactivity series. Elements above in the reactive series displaces elements present below from their salts.
The molecular equation is as follows:
Now, write the ionic equation as follows:
Cancel the common terms,
Rough, tan, grainy, and scratchy are some
Answer: P2 = 0.858 atm
Explanation:
Use the combined gas law: P1V1/T1 = P2V2/T2,
where the subscripts are the initial (1) and final (2) states. Temperature must be in Kelvin. We want P2, so rearrange the equation to solve for P2:
P2 = P1(V1/V2)(T2/T1)
Note how I've arranged the volume and temperature values: as ratios. Now it is easy to cancel units and see what is going to happen to the pressure if we lower the temperature. Since the pressure change is a function of (T2/T1), and we are lowering the temperature (T2), we'd expect this to decrease the pressure.
No information is given on volume, so we'll assume a convenient value of 1 liter. Now enter the data:
P2 = (0.917atm)*(1)*(322K/344K)
P2 = 0.858 atm
<span>Conductance gives a more accurate method to determine the salt concentration of a solution.Conductivity would be used with conductors such as metals that include copper and silver.Conductivity is a measure of water's capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds</span>
Sulfuric acid is capable of hurting the skin, eyes, paper, metals, and even stone in some cases.
