Answer:
Most similar - Lithium
Least similar - Phosphorus
Explanation:
Rubidium is an element in group 1A of the periodic table. It is a metal and forms an ionic compound with chlorine. The formula of the compound is RbCl.
If we look at the options, Lithium is also a group 1A element and forms an ionic compound with chlorine having the formula LiCl which is very much similar to RbCl chemically.
Phosphorus is a nonmetal. Its compounds with chlorine, PCl3 and PCl5 are covalent and does not resemble RbCl in any way.
Answer:
A
Explanation:
The solubility of a substance is directly proportional to the temperature. It means that solubility will increase with the increases in temperature. At higher temperature, the kinetic energy increased that allow the solvent molecules to break the solute particles more effectively.
Substance A has a higher solubility because the weight of substance A measured at the end of the experiment is less than the weight of substance B.
Hence, the correct answer is A.
Answer:
Cancel out CO because it appears as a reactant in one intermediate reaction and a product in the other intermediate reaction.
Explanation:
The CO appears twice hence in he intermediate reaction it only forms path of the enabling reagents and it further reacts to form the final product. Accounting for the CO in the intermediate reaction that undergoes further reaction will impact on the stoichiometry of the reaction.
Conduction-
putting an icepack on injury
grabbing a warm coffee mug
burning yourself by touching boiling water
the handle of a pot being to hot to touch
Convection-
heat from a fire to warm hands
warm water rising to the surface of of the ocean etc.
warm air rising off pavement
an oven that cooks by cycling warm air through the bottom and out the top
Radiation-
cooking popcorn using microwave
heat from the sun hitting a solar panel
( i havent done science in a while cuz im homeschooled but i think most of these are correct)
good luck on what your working on !!
Try d cuz if im not mistaken if you burnt white phosphorus all the gas is going to take most the air
