Answer:
single displacement reaction
Explanation:
it is because an atom(Pb) dispalces another atom(H) in H3PI4
Answer:
Swimmers health.
Explanation:
The pH is the measure of the concentration of the ions H⁺ (pH = -log[H⁺]), and it determines if the substance is acidic, basic or neutral. If pH = 7, it's neutral, if it's below 7 it's acidic, and if it's above 7, it's basic.
In pool water, chlorine is added to disinfect it, by killing microorganisms. The pH of the water affects the action of the chlorine, and for a better result in disinfection, it must be between 7.0 and 7.6, so the disinfection will happen and the swimmers' health will be protected.
Memorize that molarity = moles/liters and you can get these
Answer:
Uracil, Ribose
Explanation:
The Nitrogenous base found in RNA that is not found in DNA is called Uracil.
While the five-carbon sugar in RNA is called Ribose.
Answer: Chromium is less reactive as compared to Aluminium as it can not easily electrons as aluminium.
Explanation:
The arrangement of metals in a series according to the decreasing order of their reactivity is called reactivity series.
The metals that are placed above hydrogen are more reactive and those below hydrogen are less reactive.
A metal placed above another metal can displace lower metal from its salt solution. Thus a metal placed above in series is more reactive than metals placed below it.
As aluminium can easily lose electrons as compared to chromium , it is more reactive than Chromium.
