Answer:
your ans is battery emf v+1r
The equation is
W = C/F
W= 3.00 x 10^8 m/sec
——————————
6.165 x 10^14 Hz
W= 4.87 x 10^-7 m
Energy is
E=hF
E= (6.626 x 10^-34 Jxsec )(6.165 x 10^14 Hz)
E= 4.085 x 10^-19 J
Answer :
Compound : It is a mixture of elements which are chemically bonded together in a fixed proportions.
(a) Citric acid, 
In this compound, there are three types of elements present carbon, hydrogen and oxygen. There are 6 atoms of carbon element, 8 atoms of hydrogen element and 7 atoms of oxygen element.
(b) Glycine, 
In this compound, there are four types of elements present carbon, hydrogen, nitrogen and oxygen. There are 2 atoms of carbon element, 5 atoms of hydrogen element, 1 atom of nitrogen element and 2 atoms of oxygen element.
(c) Chloroform, 
In this compound, there are three types of elements present carbon, hydrogen and chlorine. There are 1 atom of carbon element, 1 atom of hydrogen element and 3 atoms of chlorine element.
(d) Sulfur hexafluoride, 
In this compound, there are two types of elements present sulfur and fluorine. There are 1 atom of sulfur element and 6 atoms of fluorine element.
<span>At constant temperature and moles, the answer can simply becomes P1V1 = P2V2. The original sample is 760 torr and 5.00 l, and was then compressed to 3.00 l. (760 torr)(5.00 l ) = (3.00 l)(X torr), X = 1270 torr. The new pressure exerted by helium on its container is 1270 torr.</span>
