NH₄Cl → NH₄⁺ + Cl⁻
NH₄⁺ (the ammonium cation)
Answer:
Refrigerator
Explanation:
Think about it. Equilibrium is between 2 "places", and if you didn't open the fridge, there would be a buildup of cold air.
Because of that buildup, it would keep getting colder until it isn't possible to get cold anymore. That is equilibrium.
However, if you were to open the door for a very, very long time, you would lower the temp. inside the fridge, therefore causing for the room you are in to be slightly colder, and the fridge to decrease in cold. The fridge will still be slightly cold, but it won't be lukewarm if you leave it for 2 hours. (Unless it's broken)
That is equilibrium :)
Answer:
Ex1 = 4.3 moles
Explanation:
for Ex 1
** Number of mole = Mass (g) / Molecular weight ' Mw' (g/mole)
for a = NaCl , first you must be calculate Mw = look to periodic table
Atomic weight for Na is 22.9 = 23 g and for Cl is 35.45 = 35 g
so Mw for NaCl = 23+35 = 58 g/mole
so Number of Moles for NaCl 250 g is
Number of Moles = 250 / 58 = 4.3 moles
do same for others ...
good luck ..
Answer:
D.
Explanation:
Genetic Engineering is a huge part in manipulating a foods property. Chemical engineering mostly the science with numbers in foods.
Biology is literally the life of the food.
