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.
5o2 is a Compound not an element
Answer:
B; 4 L
Explanation:
From the Boyle’s law of gases, the volume occupied by a given mass of gas is inversely proportional to the pressure exerted by the gas
Mathematically, we have this as;
PV = K
Given;
P1 = 2 atm
V1 = 12 l
P2 = 6 atm
V2 = ?
We have that;
P1V1 = P2V2
2 * 12 = 6 * V2
V2 = (2 * 12)/6
V2 = 24/6
V2 = 4 L
Hello!
K⁺ and F⁻ are the more likely to form an ionic bond.
Ionic bonds are the result of the electrostatic attraction between positive and negative ions (charged atoms). Of the listed substances, the ones that are charged are K⁺ and F⁻, so they are the ones that will form ionic bonds. Some ionic substances made from K⁺ include KCl (used in fertilizers) and some ionic substances made from F⁻ include NaF (used in dental therapy).
Have a nice day!
