When cohesive force is stronger than the adhesive force: concave up meniscus, water forms droplets on surface
AB+XY->AY+XB
We know that the answer would be KCl because of the switching that takes place during a double displacement reaction. Just like Zn and MnO4 switched and combined, the remaining elements, K and Cl, will combine.
We know that the answer is simply KCl because both K and Cl have an ion of only +/-1, meaning when they cross, no suffixes are made, since their ions are only 1.
For example, if you combined Mg with Cl, you would get MgCl2, because Mg has an ion of +2.
I hope this helps!
I think it’s the first one. Electroplating means you put on a layer of metal on something.
Since abiotic is a non living factor B would be the answer because water is abiotic
