Hcl furnace is running at a flow rate of 500nm3/hr of hydrogen and 400nm3/hr chlorine, all the vapors of hcl are scrubbed in a fumes absorber ,calculate dm water flow rate in m3/hr so as to produce 31%hcl solution as product

hcl vapors are absorbed by dm water spray in fumes absorber and gave final product as hcl solution.

i think its 5049.

i hope this !

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
