After a radioactive atom decays, it is the same element that it
was before with no measurable change in mass. the decay that is present is
gamma decay because gamma decay has photons which has no mass unlike alpha and
beta decay.
Answer:
Improved water supply and sanitation and improved water resources management boost countries' economic growth and contributes greatly to poverty eradication. ... National economies are more resilient to rainfall variability, and economic growth is boosted when water storage capacity is improved
Explanation:
Okey so 1st find the moles of F2 which is :
n = 15/22.4 = 0.667mol
Then according to stoichiometric values, F2 and NaCl, they are to a ratio of 1 : 2
So take the twice value of the calculated moles.
Use the moles to find the mass using the equation :
m = n×M
Where m is the mass
n is moles
M is molar mass (of NaCl)
Therefore m = 1.334×57.5
(given the molar mass of Na 22gmol^-1 and CL 35.5gmol^-1)
m = 76.705g
