<h2>Answer : 1 is gamma, 2 is alpha and 3 is beta radiations.</h2><h3>Explanation :</h3>
In the given information all the radiations were stopped by the lead block, if we assume that first radiations were gamma radiation, as they were not stopped by the cloth whereas all other radiations were stopped.
In second case, aluminum foil and wood were able to block alpha and beta radiations. Whereas, paper was used to stop the alpha particles but not the gamma and beta rays. And then a thick concrete stopped all the radiations.
This clarifies that the first radiation are gamma rays, second is alpha rays and third is beta rays.
Answer:
Neon(Ne)
Explanation:
Neon will not react because it is a noble gas and had 8 electrons.
Answer:
Four different reagent where used 1) BH3 & 2) H2O2/NaOH to produce butanol, followed by 3)PBr3 to produce Bromobutane and finally 4) NaOBu to produce the dibutylether
Explanation:
Please find attached the step by step reaction
It is true because protons are positively charged and electrons are negatively charged. if there is the same number of protons and electrons, both charges cancel out.
