Dependent could be the amount of water, the time that you are using in the u tube. Independent could be the amount of hydrogen and oxygen gass.
Remember, dependent variable is something that you control or measurement. Like for example. You have 2 different tubes one with 5ml of water and the other one with 10ml.
Independent something you cannot control. Like the amount of light can a plant receive or how much long it will take water to boil depending on the how high the fire is

Alkali metals<span> include </span>lithium<span>, sodium, potassium, rubidium, cesium and francium. These </span>metals<span> have large atomic radii and generally lose electrons during reactions. They have relatively soft textures, which makes them easy to mold, shape and dissect for </span><span>various uses</span>
A thing that is composed of tow or more seperate elements
The answer is <span>a. Rubidium
A cation is an ion that has a positive charge. The charge positive because it loses electrons. The radius of an atom is influenced by the electron because it is found at the outer layer of the atom. Since cation has less electron and anion get more electron, the radius of cation will be smaller than anion.
Rubidium is the biggest cation because it is located in the lowest row, thus having most electron count.</span>
