The empirical formula is the lowest reduced ration of the atoms present. In this case, it is P2O5
Answer:
A liquid with a sharp contact angle (e.g., water on glass) will form a concave meniscus, and the liquid pressure under the meniscus will be smaller than the atmospheric pressure
Explanation:
The phenomenon of capillarity is produced by the action of the surface tension of the fluids and is observed when a small diameter tube is immersed within the fluid. If we pay attention to the result, we can see that, depending on the fluid, two different things can happen, that the liquid rises through the tube and that the level inside the tube is greater than that of the liquid or that the opposite happens.
The case in which the liquid rises above the tube occurs when the liquid "wets". This occurs when the adhesion forces with the walls exceed those of cohesion between the fluid molecules. In this case, the concave side is out of the fluid.
The case where the level of the liquid inside the tube is lower than the level of the liquid occurs when the liquid does not get wet. We remember that the liquid does not get wet when the cohesion forces are greater than those of adhesion. This phenomenon is called capillary depression and the concave angle is for the liquid side and is said to be convex.
The answer for above statement is:
p4(s)+10hclo(aq)+6h2o(l)→4h3po4(aq)+10hcl(aq) br2(l)+2k(s)→2kbr(s) ch3ch2oh(l)+3o2(g.
Explanation:
An reaction (redox) reaction may be a style of chemical process that involves a transfer of electrons between 2 species. An redox reaction any chemical process during which the oxidation state of a molecule, atom, or particle changes by gaining or losing an electron.
The properties of the elements can be determined from their electron configuration
