Answer:
occur if two of the ions form an insoluble ionic compound, which precipitates out of solution
Explanation:
When two ionic compounds are dissolved in water, a double replacement reaction takes place if two of the ions form an insoluble ionic compound, which precipitates out of solution. In double displacement reaction ions switch partners. And hence, produce an insoluble precipitate.
Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate
<h3>What is concentration?</h3>
A solution is made up of two components, solute and solvent. In chemistry, we define the concentration of solution as the amount of solute dissolved in the solution.
Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.
Hence, Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate.

Answer:
Average temperatures in July range from 85°F to 90°F during the day but cool off quickly after dark, dropping into the 50s and 60s (°F). Some regions of Wyoming are classified as desert, so there isn't much precipitation. Most of it falls as rain in the late spring and early summer, which is also a windy time of year.
Explanation:idk if this helps awnser ur question
Answer:
KI
Explanation:
From the question, we can see that a qualitative analysis of the compound shows that it has a lilac flame colour. The lilac flame colour corresponds to the potassium ion (K^+).
Again, the test of addition of HNO3(aq) and AgNO3(aq) to a solution is a test for halogens. If the result is a green precipitate, then the ion present is the iodide ion (I^-).
Hence, the compound must be KI.
