PLEASE HELP ME THIS ITS JUST ONE SOMPLE QUESTION THAT I CANT SEEM TO GET. A student is making a wet-mount preparation of onion epidermis cells for observation with a compound light microscope. The student cuts off a slice of onion, places it on a side, adds iodine, puts the slide on the stage, and rotates the nosepiece on the microscope to the highlife objective. using one or not complete sentence,

Question/what the assignment is looking for:

state one error in the procedures followed by the student.

what is the question here. i think you messed up.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

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.
