Ten thousand kg per hour of a liquor with 10% solids is fed at 294 k to the 1" effect of a double-effect unit. liquor with 50% solids is to be widthrawn from the second effect, which is at a pressure of 0.13 bar. the liquor will be assumed to have a specific heat of 4.18 kj/kg-k and to have no bpr. saturated steam at 205 kn/m2 is fed to the heating element of the first effect. if both units are to have equal areas, estimate the steam consumption and the areas of each effect. assume heat transfer coefficients of 3.1, and 2.0 kw/m2-k for the first and second effects, respectively

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

i think that the answer is c

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.
